description: The discovery and synthetic applications of novel organoselenium compounds and their reactions proceeded rapidly during the past fifty years and such processes are now carried out routinely in many laboratories. At the same time, the growing demand for new enantioselective processes provided new challenges. The convergence of selenium chemistry and asymmetric synthesis led to key developments in the 1970s, although the majority of early work was based on stoichiometric processes. More recently, greater emphasis has been placed on greener catalytic variations, along with the discovery of novel reactions and a deeper understanding of their mechanisms. The present review covers the literature in this field from 2010 to early 2023 and encompasses asymmetric reactions mediated by chiral selenium‐based reagents, auxiliaries and, especially, catalysts. Protocols based on achiral selenium compounds in conjunction with other species of chiral catalysts, as well as reactions that are controlled by chiral substrates, are also included.
The Datafication of Open Banking: A critical interrogation into the data privacy issues and cybersecurity risk implications of cross-border data flows under Canada’s proposed Open Banking Framework

description: Banks have always served as the chief custodians of financial data and in this role, they regulate the activities between customers, technology, and merchants. The worldwide consumer demands have added pressure to financial institutions to adopt more streamlined methods when it comes to accessing financial data. This comes at a time when the financial services industry sits on the verge of pending reforms through digitisation and crossborder transactions. Open banking is one such change which is predicted to shake up the traditional banking model and is expected to bring a plethora of benefits to both customers and the financial industry. Open banking provides access to consumer banking, transactions, and other financial information to third party providers (TPPs) via application programming interfaces (APIs). Open banking has the possibility of expanding to include user consent-based movement of information for investments, insurance, telecommunications, utilities and more. This ability to share financial data through APIs could promote faster, easier, and more secure payments, particularly crossborder transactions. There are three major challenges with open banking that this research covers. The first is that open banking introduces a consumer data portability feature at a time when there is no existing right under the current law. The second is that open banking is a consent-based system that will require a higher standard of consent from a privacy law perspective especially in relation to crossborder transactions. The third is that open banking exacerbates existing cybersecurity risks while creating new ones which may require additional protections through either the financial or privacy law regimes. It is useful to explore that each country imposes separate regulatory limits on what personal data can be transferred or stored in their markets and whether there can ultimately be interoperability of these structures for crossborder transactions. Open banking raises concern that it may become a dangerous route for criminals to trick naïve consumers into disclosing secret information, allowing illegal access to their personal data. As such, there is no room for error in rolling out open banking as a model, as its failure could result in harsh economic impacts across the financial sector.

description: Citizen preferences play a key role in a democracy, and there is a substantial body of work that tries to understand the role that public preferences play in the policy process. Despite the important role public opinion plays, there are only limited efforts to document public opinion about education, psychology, and health. The Public Mind project seeks to address this gap by providing reliable, valid public opinion data to inform public debate. The Project includes a series of public opinion surveys on a variety of issues related to governance, policies, and practice that have the potential to affect human development. This research brief examines Americans' views of stakeholders in education: parents, teachers, teacher unions, academic researchers, business leaders, and think tanks. Whereas in the past only elected officials were considered legitimate policy actors, today there are more groups of people competing to shape education policy. But we know very little about which stakeholders are seen as credible by the public, and why.

description: We extend the dipole formalism for massless and massive partons to random polarisations of the external partons. The dipole formalism was originally formulated for spin-summed matrix elements and later extended to individual helicity eigenstates. For efficiency reasons one wants to replace the spin sum by a smooth integration over additional variables. This requires the extension of the dipole formalism to random polarisations. In this paper we derive the modified subtraction terms. We only modify the real subtraction terms, the integrated subtraction terms do not require any modifications.

description: Science suggests that killing coyotes increases human-coyote conflict and decreases ecosystem health. Yet approximately half a million coyotes are killed every year in the United States, and numbers in Canada are inconclusive but likely commensurate. Despite coyotes living in North America for millennia, little information is available on what influences a person's willingness to coexist with the species. People’s emotions are valuable to consider when exploring human-coyote relationships since emotions guide an individual’s reactions, beliefs, and perceptions toward wildlife. To date, research examining emotions in human-coyote relationships has primarily used quantitative methods and focused on fear. The existing research has highlighted the value of considering emotions to understand human-coyote relationships better. Still, there is a need for qualitative contributions to acknowledge why people have certain emotions and how their emotions impact their tolerance for coyotes – if at all. Using 46 in-situ interviews with residents of the Foothills Parkland Natural Region of Alberta, Canada, collected as part of the Foothill Coyote Initiative, I conducted a mixed-methods analysis that explores people’s emotions toward coyotes, what drives these emotions, and how these emotions relate to individuals’ willingness to adopt or support lethal and nonlethal methods used on coyotes. Through narrative responses and emoticon data, I conclude that different contexts influence emotions toward coyotes and that the more positively interviewees felt about coyotes overall and the more negatively they felt when a coyote needed to be killed, the less likely they were to prefer lethal methods as a form of coyote management. The findings from this research offer a foundation for future studies and opportunities to create targeted educational materials that encourage the adoption and support of management methods that reduce human-coyote conflict without compromising ecosystem health.

description: Motivated by the recent argument that in the TeV-scale gravity trans-Planckian domains of spacetime as effective naked singularities would be generated by high-energy particle (and black-hole) collisions, we investigate the quantum particle creation by naked-singularity formation in general dimensions. Background spacetime is simply modeled by the self-similar Vaidya solution, describing the spherical collapse of a null dust fluid. In a generic case the emission power is found to be proportional to the quadratic inverse of the remaining time to a Cauchy horizon, as known in four dimensions. On the other hand, the power is proportional to the quartic inverse for a critical case in which the Cauchy horizon is `degenerate'. According to these results, we argue that the backreaction of the particle creation to gravity will be important in particle collisions, in contrast to the gravitational collapse of massive stellar objects, since the bulk of energy is carried away by the quantum radiation even if a quantum gravitational effect cutoff the radiation just before the appearance of naked singularity.

description: We have previously reported that Ildr2 knockdown via adenovirally-delivered shRNA causes hepatic steatosis in mice. In the present study we investigated hepatic biochemical and anatomic phenotypes of Cre-mediated Ildr2 knock-out mice. Liver-specific Ildr2 knock-out mice were generated in C57BL/6J mice segregating for a floxed (exon 1) allele of Ildr2, using congenital and acute (10-13-week-old male mice) Cre expression. In addition, Ildr2 shRNA was administered to Ildr2 knock-out mice to test the effects of Ildr2 shRNA, per se, in the absence of Ildr2 expression. RNA sequencing was performed on livers of these knockdown and knockout mice. Congenital and acute liver-specific and hepatocyte-specific knockout mice did not develop hepatic steatosis. However, administration of Ildr2 shRNA to Ildr2 knock-out mice did cause hepatic steatosis, indicating that the Ildr2 shRNA had apparent “off-target” effects on gene(s) other than Ildr2. RNA sequencing and BLAST sequence alignment revealed Dgka as a candidate gene mediating these “off-target” effects. Ildr2 shRNA is 63% homologous to the Dgka gene, and Dgka expression decreased only in mice displaying hepatic steatosis. Dgka encodes diacylglycerol kinase (DGK) alpha, one of a family of DGKs which convert diacylglycerides to phosphatidic acid for second messenger signaling. Dgka knockdown mice would be expected to accumulate diacylglyceride, contributing to the observed hepatic steatosis. We conclude that ILDR2 plays a negligible role in hepatic steatosis. Rather, hepatic steatosis observed previously in Ildr2 knockdown mice was likely due to shRNA targeting of Dgka and/or other “off-target” genes. We propose that the gene candidates identified in this follow-up study may lead to identification of novel regulators of hepatic lipid metabolism.

description: A number of candidate theories beyond the standard model (SM) predict new scalar bosons below the TeV region. Among these, the radion, which is predicted in the Randall-Sundrum model, and the dilaton, which is predicted in spontaneous scale symmetry breaking, have very similar couplings to those of the SM Higgs boson, and it is very difficult to differentiate these three spin-0 particles in the expected signals of the Higgs boson at the LHC and Tevatron. We demonstrate that the observation of the ratio sigma(gamma gamma)/sigma(WW) gives a simple and decisive way, independently of the values of model parameters: the VEVs of the radion and dilaton fields.

description: In Canada, the shift in global human rights law reform, is felt when there is a need to support Indigenous self-governance through policy and regulations. Moreover, much of the law reform that attempts to positively affect Indigenous autonomy is not well understood by the general public, researchers, or service providers. Within the area of Indigenous water management few studies examine how the status of First Nation's decision-making authority and readiness limit their infrastructure and resource management capacity. Through collaboration with Indigenous Elders, this study contributes to understanding the concept of sustainable water management using an Indigenous centred lens. The research methods were framed using a concept developed by Treaty Four Elders and academics who coined the Four Healing Protective Factors (Four PFs). The Four PFs were used to guide the literature review and method development in a trauma-informed, strength-based, community-specific, and spiritually grounded way. Using the Four PFs, a semi-structured grounded theory data collection method showed a causal relationship between existing water management and the need for holistic solutions to water challenges. The conceptual framework supports self-governance through a perspective shift during research scoping, methods, and products to build using Indigenous culture. A method was needed to validate Indigenous and non-Indigenous conflict, improve infrastructure and resource management, while ruling out misconceptions about where Indigenous water culture stems from. Ultimately, the framework ensures the integration of the Nation’s history and uplifts Indigenous culture to ensure the community is not decentralized and pulled away from their preferred methods of operating.

description: The post-sunset equatorial ionosphere is a scientifically intriguing region with implications for space weather and challenges for GNSS/GPS technologies. In this thesis, we carry out three separate research projects involving ultra-low-frequency waves and plasma density fluctuations using data from the Swarm satellite mission to enhance our understanding of this ionospheric region. In the first study, we explore interhemispheric magnetic field-line resonances (FLRs) during quiet times after sunset. We identified 26 FLRs, including one at the lowest reported magnetic latitude (2 degrees). Notably, in four instances, these waves were seen in both hemispheres during a Swarm pass, demonstrating that the waves extend along the entire field line. The fundamental frequency of these FLRs decreased as the field line length increased, in accordance with the theory. The second study centers on electromagnetic fluctuations within plasma bubbles. We observed strong coherency between electric and magnetic fields, reaching up to 5 Hz, with a phase shift of nearly 90◦. This observation along with changes in the Poynting vector sign within plasma bubbles are consistent with standing waves. The field-aligned length of plasma bubbles estimated using the fundamental frequency and Alfv´en wave speed is 100-200 km, and is consistent with the estimated based on the satellites’ dwell time within bubbles, pointing to an unexpected degree of structure along B-field lines. The final study utilizes nearly ten years of Swarm mission plasma data in the post-sunset equatorial ionosphere. The integrated power of plasma density for each 1-minute interval of plasma density measurements in the equatorial ionosphere is calculated. A similar analysis was conducted for loss of navigational capability (LNC) events. The probability distribution functions of these signals exhibited a power-law behavior, implying potential self-organized criticality in plasma density fluctuations during the post-sunset equatorial period. Integrated power for almost all LNC events is concentrated in the high-intensity portion of a heavy-tail probability distribution function, indicating that systems adhering to a normal or close-to-normal distribution would not generate fluctuations sufficiently intense to cause LNC.

description: Cholinergic dysfunction is strongly implicated in dystonia pathophysiology. Previously (Pappas et al., 2015;4:e08352), we reported that Dlx5/6-Cre mediated forebrain deletion of the DYT1 dystonia protein torsinA (Dlx-CKO) causes abnormal twisting and selective degeneration of dorsal striatal cholinergic interneurons (ChI) (Pappas et al., 2015). A central question raised by that work is whether the ChI loss is cell autonomous or requires torsinA loss from neurons synaptically connected to ChIs. Here, we addressed this question by using ChAT-Cre mice to conditionally delete torsinA from cholinergic neurons (‘ChAT-CKO’). ChAT-CKO mice phenocopy the Dlx-CKO phenotype of selective dorsal striatal ChI loss and identify an essential requirement for torsinA in brainstem and spinal cholinergic neurons. ChAT-CKO mice are tremulous, weak, and exhibit trunk twisting and postural abnormalities. These findings are the first to demonstrate a cell autonomous requirement for torsinA in specific populations of cholinergic neurons, strengthening the connection between torsinA, cholinergic dysfunction and dystonia pathophysiology.

description: When a Body Sprouts is a novel of speculative fiction and body horror. Set in the fictional city of Eden Prairie, the novel follows the protagonist, Telli—a transracial adoptee, who lives with a fictional autoimmune disease known as phylloderma: a condition which causes plants to grow outside of her body, generating various symptoms from hallucinogenic behaviours to the tightening of connective tissues. Used to a life of chronic-pain and living paycheck to paycheck, Telli works as a waitress at The Rhino. But when an encounter with her estranged adoptive mother and a Suit causes her symptoms to accelerate, Telli struggles to find meaning in her life as the structural powers that be continue to exploit her labour. Unable to control the constant sprouting of vegetal life and her dreams of faceless workers, Telli copes through cutting, collecting and preserving the very things which harm her. Delving into race, gender, class and environmental complexities, When a Body Sprouts focuses on the painful ripple effect of colonialism on racialized bodies and the more-than-human, while showcasing the capacity for renewal and patching together a fragmented life into something akin to a whole.

description: In the last two years, the endeavor of realizing FAIR Digital Objects (FDOs) took a huge leap on the international as well as on the national level in Germany and in particular within HMC. By finding consensus on a common Helmholtz Kernel Information Profile defining basic kernel metadata attributes each FDO must provide to serve as top-level commonality across all research fields, the way was paved to bring FDOs into practice. The initial focus was on technical aspects on how to create and manage FDOs, which resulted in documents, infrastructure components, and tools addressing these aspects. Early adoptions were carried out in different contexts, e.g., in NFDI-MatWerk to create a set of reference datasets for different participant projects, in collaboration with the Helmholtz incubator platform on AI to represent a complex dataset of annotated images, and in different HMC Hubs and projects. It quickly became apparent that a growing number of FDOs also has an impact on their design and handling. A better understanding of common practices of creating FDOs in different domains also increased their complexity, which brought up a strong demand on additional tooling to fill existing gaps with regard to the creation, management, retrieval, and representation of FDOs. On this poster we present our results on addressing the creation, retrieval, and representation of FDOs. For the creation of FDOs the FDO Creator was implemented to ease the manual creation of small to mid-size FDO graphs. Realized on top of the Typed PID Maker, the FDO Creator simplifies the creation of validated FDOs and their linking to each other. Once created, the retrieval of FDOs becomes relevant for scientific users. With this in mind, the FDO Search (8) is taking the first steps to implement a user-friendly search for FDOs. Based on PID Records indexed by the Typed PID Maker in an Elastic instance, full text as well as faceted search are offered to the user. Single results can then be visualized either in FAIR-DOscope or by one of the new reusable Web Components for visualizing FDOs as graphs or rendered as text components, offering multiple ways for further interaction. The strong focus on the reusability aspect of the created Web Components will ease the integration of FDOs into existing software, as well as increase their acceptance by making them tangible for scientific users. Allowing FDOs to be visualized in basically every Research Software Environment will improve their visibility and will foster a natural interaction as part of a researcher’s daily business, hiding technical details of a FDO’s implementation. This research has been supported by the Helmholtz Metadata Collaboration (HMC) Platform, theGerman National Research Data Infrastructure (NFDI) and the German Research Foundation (DFG).

description: The spectrum of electron-phonon complexes in a monolayer graphene is investigated in the presence of a perpendicular quantizing magnetic field. Despite the small electron-phonon coupling, usual perturbation theory is inapplicable for calculation of the scattering amplitude near the threshold of the optical phonon emission. Our findings beyond perturbation theory show that the true spectrum near the phonon emission threshold is completely governed by new branches, corresponding to bound states of an electron and an optical phonon with a binding energy of the order of $αω_{0}$ where $α$ is the electron-phonon coupling and $ω_{0}$ the phonon energy.

description: In the supervised learning setting termed Multiple-Instance Learning (MIL), the examples are bags of instances, and the bag label is a function of the labels of its instances. Typically, this function is the Boolean OR. The learner observes a sample of bags and the bag labels, but not the instance labels that determine the bag labels. The learner is then required to emit a classification rule for bags based on the sample. MIL has numerous applications, and many heuristic algorithms have been used successfully on this problem, each adapted to specific settings or applications. In this work we provide a unified theoretical analysis for MIL, which holds for any underlying hypothesis class, regardless of a specific application or problem domain. We show that the sample complexity of MIL is only poly-logarithmically dependent on the size of the bag, for any underlying hypothesis class. In addition, we introduce a new PAC-learning algorithm for MIL, which uses a regular supervised learning algorithm as an oracle. We prove that efficient PAC-learning for MIL can be generated from any efficient non-MIL supervised learning algorithm that handles one-sided error. The computational complexity of the resulting algorithm is only polynomially dependent on the bag size.

In most societies, the management of menstruation is handled covertly, something girls are often instructed about at menarche. The management of other vaginal bleeding is often similarly discreet, although behaviours are not well documented. In many societies, cultural taboos frequently hinder open discussion around vaginal bleeding, restricting information and early access to healthcare. Additionally, the limited availability of clean, accessible water and sanitation facilities in many low and middle-income countries augments the challenges girls and women face in conducting daily activities while managing vaginal bleeding, including participating in school or work, going to the market or fetching water. This paper aims to highlight the key vaginal bleeding experiences throughout a woman’s life course and the intersection of these bleeding experiences with their access to adequate water and sanitation facilities, information and education sources, and supplies. The aim is to address the silence around girls and women’s vaginal bleeding and their related social, physical and clinical management needs across the life course; and highlight critical gaps that require attention in research, practice and policy around this neglected topic of health and gender equality.

description: In this thesis, I investigate near-surface seismic properties and several geophysical methods mainly including surface wave dispersion inversion (SWDI) and full waveform inversion (FWI) for CO2 monitoring, focusing on the capabilities of Distributed Acoustic Sensing (DAS) technology. The study is underpinned by data collected from Newell County Facility, Alberta, Canada, employing seismic data acquired from both surface-deployed and vertical seismic profi le (VSP) DAS fiber. DAS data, characterized by broadband and dense spatial sampling, facilitate the extraction of high-resolution near-surface velocity pro les due to their enhanced signal-to-noise ratio and resolution in low-frequency components and multimode dispersion curves. The first segment of the study introduced several types of dispersion curves, explores trans-dimensional (TD) inversion, employing multimode dispersion curves and reversible-jump Markov Chain Monte Carlo (MCMC) sampling to generate probabilistic posterior density (PPD) estimates of model parameters. This approach yields inversion results that align well with known lithological data. This research showcases the potential of horizontal DAS data in high-resolution, near-surface investigations. Additionally, I developed a multi-step multiscale surface wave FWI. Utilizing DAS recorded surface waves, high-resolution S-wave velocity (Vs) and attenuation (quality factor Qs) models of the near-surface are obtained through FWI, offering improved lateral resolution and depth penetration compared to conventional surface-wave analysis. The inclusion of low-frequency components in DAS data effectively mitigates the cycle skipping challenge commonly associated with FWI, leading to high-resolution VS models that capture lateral variations effectively. I also addressed the challenge of noise in seismic data, particularly its impact on acoustic and elastic FWI models. By incorporating the data covariance matrix into the mis t function, this approach mitigates the effects of noise, improving the accuracy of the FWI models. Building on these methods, I applied anisotropic FWI with variable density to DAS recorded walk-away VSP data for characterizing subsurface velocity, anisotropy, and density structures. This technique, essential for time-lapse studies of CO2 injection and storage, proved effective in providing more accurate P-wave velocity, density models, and anisotropy parameters compared to isotropic FWI. In conclusion, this thesis demonstrates the potential of using DAS technology and advanced geophysical methods for near-surface investigation and CO2 monitoring. The integration of DAS data with trans-dimensional and varied FWI approaches, alongside noise mitigation strategies, offers a signi cant step forward in accurate and e cient subsurface characterization, crucial for environmental monitoring and carbon capture and storage initiatives.

description: We study the ground-state (gs) properties of the frustrated spin-1/2 $J_{1}$--$J_{2}$--$J_{3}$ Heisenberg model on a honeycomb lattice with ferromagnetic (FM) nearest-neighbor ($J_{1}=-1$) exchange and frustrating antiferromagnetic (AFM) next-nearest-neighbor ($J_{2}>0$) and next-next-nearest-neighbor ($J_{3}>0$) exchanges, for the case $J_{3}=J_{2}$. We use the coupled cluster method in high orders of approximation, complemented by the exact diagonalization of a lattice with 32 sites, and calculate the gs energy, magnetic order parameter, and spin-spin correlation functions. We find a quantum phase transition between regions characterized by FM order and a form of AFM ("striped") collinear order at $J^{c}_{2} \approx 0.1095 \pm 0.0005$. We compare results for the FM case (with $J_{1}=-1$) to previous results for the corresponding AFM case (with $J_{1}=+1$). While the magnetic order parameters behave similarly for the FM and the AFM models for large values of the frustration parameter $J_{2}$, there are considerable differences between them for $J_{2}/|J_{1}| \lesssim 0.6$. For example, the quasiclassical collinear magnetic long-range order for the AFM model (with $J_{1}=+1$) breaks down at $J^{c_{2}}_{2} \approx 0.60$, whereas the "equivalent" point for the FM model (with $J_{1}=-1$) occurs at $J^{c}_{2} \approx 0.11$. Unlike in the AFM model (with $J_{1}=+1$), where a plaquette valence-bond crystal phase intrudes between the two corresponding quasiclassical AFM phases (with Néel and striped order) for $J^{c_{1}}_{2} < J_{2} < J^{c_{2}}_{2}$, with $J^{c_{1}}_{2} \approx 0.47$, we find no clear indications in the FM model for an intermediate magnetically disordered phase between the phases exhibiting FM and striped order. Instead, the evidence points strongly to a direct first-order transition between the two ordered phases of the FM model.

description: Supertropical matrix theory was investigated in [6], whose terminology we follow.

description: Images taken in the band centered at 30.4 nm are routinely used to map the radiance of the He II Ly alpha line on the solar disk. That line is one of the strongest, if not the strongest, line in the EUV observed in the solar spectrum, and one of the few lines in that wavelength range providing information on the upper chromosphere or lower transition region. However, when observing the off-limb corona the contribution from the nearby Si XI 30.3 nm line can become significant. In this work we aim at estimating the relative contribution of those two lines in the solar corona around the minimum of solar activity. We combine measurements from CDS taken in August 2008 with temperature and density profiles from semiempirical models of the corona to compute the radiances of the two lines, and of other representative coronal lines (e.g., Mg X 62.5 nm, Si XII 52.1 nm). Considering both diagnosed quantities from line ratios (temperatures and densities) and line radiances in absolute units, we obtain a good overall match between observations and models. We find that the Si XI line dominates the He II line from just above the limb up to ~2 R_Sun in streamers, while its contribution to narrowband imaging in the 30.4 nm band is expected to become smaller, even negligible in the corona beyond ~2 - 3 R_Sun, the precise value being strongly dependent on the coronal temperature profile.

Effect of nanoclay fillers on wood adhesives and particle board properties

description: The objective of this research is to investigate the effect of nanoclay additions to particleboard resins on the properties of particleboard made with those resins. Two nanoclays, Cloisite30B, a modified nanoclay and Nanofil16, an unmodified clay, were blended with the two resins used to produce particleboard: Urea Formaldehyde (UF) and Melamine Formaldehyde (MF). Coupling agent was added to nanoclays to facilitate clay dispersion into the resin. X-ray diffraction tests showed that mechanical mixing was sufficient to exfoliate Closite30B into both resin types and enable the intercalation of Nanofil116/resin mixtures. Addition of nanoclays and coupling agents had small to severe adverse effects on resin curing: Cloisite30B slightly delayed the curing process of both UF and MF resin and reduced the reaction heat of curing, and the addition of coupling agent together with Closite30B further compounded this effect. Nanofil116 significantly delayed the curing reaction of both resins and decreased the heat of reaction. The coupling agent had a significant further detrimental effect on the resin cure. In order to test whether nanoclays had a positive or negative effect on the adhesive strength of UF and MF resins, the shear strength of clay-modified resin were tested and compared with that of unadulterated resin. Regardless of whether coupling agent was used, the clay-modified UF resin had lower bonding strength than pure UF resin. In contrast, three kind of clay-modified MF resin had higher bonding strength then pure MF resin. Based on these findings those MF resins which have higher shear strength were blended with furnish to fabricate particle board using different clay loading rates. Most clay treatments had no significant effect on particleboard physical or mechanical properties. The only significant improvement was for internal bond strength which increased when using either 2% Closite30B or Nanofil116 with or without coupling agent. Higher clay loading rates tended to decrease board strength properties. In conclusion, the modified Closite30B nanoclay and the unmodified Nanofil116 nanoclay had only a minor effect on improving UF and MF resin strength and the particle board properties.
