description: 1.    Geodiversity offers novel insights into biodiversity patterns and their underlying mechanisms, thereby contributing to the development of conservation strategies amid widespread environmental changes and human disturbances. However, the relationship between geodiversity and biodiversity remains largely unexplored, particularly in freshwater ecosystems. Here, we investigated the extent to which geodiversity accounts for fish diversity across dimensions (taxonomic, functional, and phylogenetic) and levels (alpha and beta) of biodiversity in the Lancang-Mekong River.2.    We first compiled three freshwater fish datasets (i.e., occurrence records, functional traits, and phylogenetic relations) and seven geofeature group datasets (i.e., discharge, waterbody, topography, terrestrial cover, landform, soil, and rock) of the catchment. Multidimensional fish diversity and geodiversity were then calculated at alpha and beta levels, respectively. Next, we assessed the influence of geodiversity on multidimensional fish diversity at corresponding levels using generalized linear mixed models (GLMMs) and structural equation models (SEMs).3.    Multidimensional fish diversity showed congruentcontrast patterns across diversity levels, with alpha diversity showing positive upriver-downriver gradients, but beta diversity showing negative gradients along the river continuum. The spatial congruence in geodiversity was weak across geofeatures and diversity levels. Geodiversity substantially accounted for the variance in fish diversity and had consistent effect directions across biodiversity dimensions at correspondingat both alpha and beta levels, with conditional R2 in GLMMs ranging from 0.892 to 0.996. The increase in alpha fish diversity was primarily driven by the growing heterogeneityvariability of discharge and waterbody, while the increase in beta fish diversity was mainly influenced by the rising dissimilarity of discharge and soil. SEMs revealed that the indirect effects of geodiversity on fish diversity were widespread but generally weak.4.    Synthesis and applications. Our findings emphasize the profound influence of geodiversity on multidimensional fish diversity in large rivers, revealing its central role in shaping biodiversity through enhancing environmental heterogeneity and resource availability. To sustain fish diversity, it is crucial to maintain the heterogeneityvariability of discharge and waterbody and preserve holistic linkages among geodiversity components. Integrating geodiversity into conservation programs provides a robust framework for ensuring freshwater ecosystem resilience and functionality and guiding management and restoration globally, particularly in the face of rapid environmental changes.

description: Humans effortlessly establish a gist-like memory of their environment whenever they enter a new place, a memory that can guide action even in the absence of vision. Neurons in the lateral intraparietal area (LIP) of the monkey exhibit a form of this environmental memory. These neurons respond when a monkey makes a saccade that brings the spatial location of a stimulus that appeared on a number of prior trials, but not on the present trial, into their receptive fields (RFs). The stimulus need never have appeared in the neuron’s RF. This memory response is usually weaker, with a longer latency than the neuron’s visual response. We suggest that these results demonstrate that LIP has access to a supraretinal memory of space, which is activated when the spatial location of the vanished stimulus can be described by a retinotopic vector from the center of gaze to the remembered spatial location.

description: Photonic molecules - particular systems composed of coupled optical resonators - emulate the behavior of complex physical systems exhibiting discrete energy levels. In this work, we present a novel photonic molecule composed of two strongly coupled, mid-infrared ring quantum cascade lasers. We explore both experimentally and numerically the key features of the photonic molecule such as the energy level splitting of bonding and antibonding supermodes. Due to the large size of the resonators, the energy splitting results in bands containing tens of modes. Each of these modes is furthermore doubly degenerate with respect to the direction of propagation, namely clockwise and counterclockwise. We explore several methods to carefully break these symmetries of the system in a controlled manner by introducing spatial and temporal asymmetries in the pumping scheme of the ring lasers. By employing these techniques, we achieve a high degree of precision in the dynamic control of the photonic molecule. Owing to their inherent suitability for on-chip integration, this new class of devices may enable applications as varied as novel mid-infrared sensors or a rich playground for studying non-Hermitian photonics and quantum optics with quantum cascade lasers.

description: The safe application of reinforcement learning (RL) requires generalization from limited training data to unseen scenarios. Yet, fulfilling tasks under changing circumstances is a key challenge in RL. Current state-of-the-art approaches for generalization apply data augmentation techniques to increase the diversity of training data. Even though this prevents overfitting to the training environment(s), it hinders policy optimization. Crafting a suitable observation, only containing crucial information, has been shown to be a challenging task itself. To improve data efficiency and generalization capabilities, we propose Compact Reshaped Observation Processing (CROP) to reduce the state information used for policy optimization. By providing only relevant information, overfitting to a specific training layout is precluded and generalization to unseen environments is improved. We formulate three CROPs that can be applied to fully observable observation- and action-spaces and provide methodical foundation. We empirically show the improvements of CROP in a distributionally shifted safety gridworld. We furthermore provide benchmark comparisons to full observability and data-augmentation in two different-sized procedurally generated mazes.

description: We present a carefully selected sub-sample of Swift Long Gamma-ray Bursts (GRBs), that is complete in redshift. The sample is constructed by considering only bursts with favorable observing conditions for ground-based follow-up searches, that are bright in the 15-150 keV Swift/BAT band, i.e. with 1-s peak photon fluxes in excess to 2.6 ph s^-1 cm^-2. The sample is composed by 58 bursts, 52 of them with redshift for a completeness level of 90%, while another two have a redshift constraint, reaching a completeness level of 95%. For only three bursts we have no constraint on the redshift. The high level of redshift completeness allows us for the first time to constrain the GRB luminosity function and its evolution with cosmic times in a unbiased way. We find that strong evolution in luminosity (d_l=2.3\pm 0.6) or in density (d_d=1.7\pm 0.5) is required in order to account for the observations. The derived redshift distribution in the two scenarios are consistent with each other, in spite of their different intrinsic redshift distribution. This calls for other indicators to distinguish among different evolution models. Complete samples are at the base of any population studies. In future works we will use this unique sample of Swift bright GRBs to study the properties of the population of long GRBs.

description: We constrain models of the galaxy distribution in the cosmic web using data from the Galaxy and Mass Assembly (GAMA) survey. We model the redshift-space behaviour of the 2-point correlation function (2pcf) and the recently proposed Voronoi volume function (VVF) -- which includes information beyond 2-point statistics. We extend the standard halo model using extra satellite degrees of freedom and two assembly bias parameters, $α_{\rm cen}$ and $α_{\rm sat}$, which respectively correlate the occupation numbers of central and satellite galaxies with their host halo's tidal environment. We measure $α_{\rm sat}=1.44^{+0.25}_{-0.43}$ and $α_{\rm cen}=-0.79^{+0.29}_{-0.11}$ using a combination of 2pcf and VVF measurements, representing a detection of assembly bias at the 3.3$σ$ (2.4$σ$) significance level for satellite (central) galaxies. This result remains robust to possible anisotropies in the halo-centric distribution of satellites as well as technicalities of estimating the data covariance. We show that the growth rate ($fσ_8$) deduced using models with assembly bias is about 7\% (i.e. $1.5σ$) lower than if assembly bias is ignored. When projected onto the $Ω_m$-$σ_8$ plane, the model constraints without assembly bias overlap with Planck expectations, while allowing assembly bias introduces significant tension with Planck, preferring either a lower $Ω_m$ or a lower $σ_8$. Finally, we find that the all-galaxy weak lensing signal is unaffected by assembly bias, but the central and satellite sub-populations individually show significantly different signals in the presence of assembly bias. Our results illustrate the importance of accurately modelling galaxy formation for cosmological inference from future surveys.

description: The simultaneous imaging and manipulating of neural activity could enable the functional dissection of neural circuits. Here we have combined two-photon optogenetics with simultaneous volumetric two-photon calcium imaging to measure and manipulate neural activity in mouse neocortex in vivo in three-dimensions (3D) with cellular resolution. Using a hybrid holographic approach, we simultaneously photostimulate more than 80 neurons over 150 μm in depth in layer 2/3 of the mouse visual cortex, while simultaneously imaging the activity of the surrounding neurons. We validate the usefulness of the method by photoactivating in 3D selected groups of interneurons, suppressing the response of nearby pyramidal neurons to visual stimuli in awake animals. Our all-optical approach could be used as a general platform to read and write neuronal activity.

description: Deoxynivalenol (DON) is a mycotoxin commonly found in cereals and animal feeds, which also is a carcinogen easily soluble in water. So it has drawn considerable interest in food safety. In this study, a specific aptamer named DON-A16 was developed from an immobilized ssDNA library by affinity chromatography column-based the SELEX. The complementary chain competition method for DON detection was established, and its limit of detection (LOD) was 488 ng/mL. Graphene oxide-based fluorescence quenching was developed using DON-A16 with fluorescein (FAM) label; its LOD was 200 ng/mL, and the detection time was 3 h. The recovery rate of fluorescence quenching was also detected in different samples (oat, wheat flour, corn), which showed the commercial DON ELISA kit led to an increase in repeatability, satisfactory recovery and consistency. The three-dimensional structure and the main binding site of of DON-A16 was ultimately obtained by molecular docking simulation.
Interactive effects of dispersal rate and disturbance synchrony on microarthropod diversity at multiple spatial scales : rescue effects do not increase regional richness
Creators: name: Meldrum, Gennifer Eileen
Publisher: name: University of British Columbia
Year: 2012

description: Immigration from surrounding areas is known to benefit community recovery following disturbance. However, whether such rescue effects can increase regional diversity in landscapes subject to patchy disturbance has rarely been investigated experimentally. This study manipulated landscape connectivity and disturbance synchrony in moss patches, and examined the consequences for the embedded microarthropod communities. We assembled metacommunities with two patches connected by 0, 1, or 2 corridors. Patches were left undisturbed or were disturbed asynchronously or synchronously by Tullgren funnel extraction. We found evidence of rescue effects at the local-scale for microarthropods overall, especially for the oribatids and collembolans. However these rescue effects did not result in greater regional diversity for several reasons. First, rescue effects only occurred after one of the disturbances so they did not increase average local-scale diversity and any increase in local-scale diversity was offset by increasing compositional similarity across the landscape. Competitive and trophic interactions may have diminished the expected benefit of connectivity for diversity. Finally, disturbance and isolation did not always decrease local diversity as expected, suggesting a strong role for context-dependent dispersal behaviour and in situ recovery processes. Our results indicate that rescue effects mediated by habitat corridors can improve recovery of local community diversity following disturbance, but they may not be effective at maximizing regional diversity. Predator diversity may be more likely to benefit from rescue effects than prey diversity at the regional scale.

description: On the basis of detailed first-principles calculations and semi-classical Boltzmann transport, the anisotropic thermoelectric transport properties of Bi$_2$Te$_3$ and Sb$_2$Te$_3$ under strain were investigated. It was found that due to compensation effects of the strain dependent thermopower and electrical conductivity, the related powerfactor will decrease under applied in-plane strain for Bi$_2$Te$_3, while being stable for Sb$_2$Te$_3$. A clear preference for thermoelectric transport under hole-doping, as well as for the in-plane transport direction was found for both tellurides. In contrast to the electrical conductivity anisotropy, the anisotropy of the thermopower was almost robust under applied strain. The assumption of an anisotropic relaxation time for Bi$_2$Te$_3$ suggests, that already in the single crystalline system strong anisotropic scattering effects should play a role.

description: In amyotrophic lateral sclerosis (ALS) and animal models of ALS, including SOD1-G93A mice, disassembly of the neuromuscular synapse precedes motor neuron loss and is sufficient to cause a decline in motor function that culminates in lethal respiratory paralysis. We treated SOD1-G93A mice with an agonist antibody to MuSK, a receptor tyrosine kinase essential for maintaining neuromuscular synapses, to determine whether increasing muscle retrograde signaling would slow nerve terminal detachment from muscle. The agonist antibody, delivered after disease onset, slowed muscle denervation, promoting motor neuron survival, improving motor system output, and extending the lifespan of SOD1-G93A mice. These findings suggest a novel therapeutic strategy for ALS, using an antibody format with clinical precedence, which targets a pathway essential for maintaining attachment of nerve terminals to muscle.

description: The 2023 M7.8 Kahramanmaraş/Pazarcik earthquake was larger and more destructive than what had been expected. Here we analyzed near-field seismic records and developed a dynamic rupture model that reconciles different currently conflicting inversion results and reveals spatially non-uniform propagation speeds in this earthquake, with predominantly supershear speeds observed along the Narli fault and at the southwest (SW) end of the East Anatolian Fault (EAF). The model highlights the critical role of geometric complexity and heterogeneous frictional conditions in facilitating continued propagation and influencing rupture speed. We also constrained the conditions that allowed for the rupture to jump from the Narli fault to EAF and to generate the delayed backpropagating rupture towards the SW. Our findings have important implications for understanding earthquake hazard and guiding future response efforts and demonstrates the value of physics-based dynamic modeling fused with near-field data in enhancing our understanding of earthquake mechanisms and improving risk assessment.
The Unified Effect of Data Encoding, Ansatz Expressibility and Entanglement on the Trainability of HQNNs

description: In this paper, we propose a framework to study the combined effect of several factors that contribute to the barren plateau problem in quantum neural networks (QNNs), which is a critical challenge in quantum machine learning (QML). These factors include data encoding, qubit entanglement, and ansatz expressibility. To investigate this joint effect in a real-world context, we focus on hybrid quantum neural networks (HQNNs) for multi-class classification. Our proposed framework aims to analyze the impact of these factors on the training landscape of HQNNs. Our findings show that the barren plateau problem in HQNNs is dependent on the expressibility of the underlying ansatz and the type of data encoding. Furthermore, we observe that entanglement also plays a role in the barren plateau problem. By evaluating the performance of HQNNs with various evaluation metrics for classification tasks, we provide recommendations for different constraint scenarios, highlighting the significance of our framework for the practical success of QNNs.

description: The axisymmetric collapse of a cylindrical air cavity in water follows a universal power law with logarithmic corrections. Nonetheless, it has been suggested that the introduction of a small azimuthal disturbance induces a long term memory effect, reflecting in oscillations which are no longer universal but remember the initial condition. In this work, we create non-axisymmetric air cavities by driving a metal disc through an initially-quiescent water surface and observe their subsequent gravity-induced collapse. The cavities are characterized by azimuthal harmonic disturbances with a single mode number $m$ and amplitude $a_m$. For small initial distortion amplitude (1 or 2% of the mean disc radius), the cavity walls oscillate linearly during collapse, with nearly constant amplitude and increasing frequency. As the amplitude is increased, higher harmonics are triggered in the oscillations and we observe more complex pinch-off modes. For small amplitude disturbances we compare our experimental results with the model for the amplitude of the oscillations by Schmidt et al. (2009) and the model for the collapse of an axisymmetric impact-created cavity previously proposed by Bergmann et al. (2009b). By combining these two models we can reconstruct the three-dimensional shape of the cavity at any time before pinch-off.

description: Adsorption to a surface, reversible-binding, and trapping are all prevalent scenarios where particles exhibit "stickiness". Escape and first-passage times are known to be drastically affected, but detailed understanding of this phenomenon remains illusive. To tackle this problem, we develop an analytical approach to the escape of a diffusing particle from a domain of arbitrary shape, size, and surface reactivity. This is used to elucidate the effect of stickiness on the escape time from a slab domain: revealing how adsorption and desorption rates affect the mean and variance, and providing a novel approach to infer these rates from measurements. Moreover, as any smooth boundary is locally flat, slab results are leveraged to devise a numerically efficient scheme for simulating sticky boundaries in arbitrary domains. Generalizing our analysis to higher dimensions reveals that the mean escape time abides a general structure that is independent of the dimensionality of the problem. This letter thus offers a new starting point for analytical and numerical studies of stickiness and its role in escape, first-passage, and diffusion-controlled reactions.

description: Practical schemes for measurement-device-independent quantum key distribution using phase and path or time encoding are presented. In addition to immunity to existing loopholes in detection systems, our setup employs simple encoding and decoding modules without relying on polarization maintenance or optical switches. Moreover, by employing a modified sifting technique to handle the dead-time limitations in single-photon detectors, our scheme can be run with only two single-photon detectors. With a phase-postselection technique, a decoy-state variant of our scheme is also proposed, whose key generation rate scales linearly with the channel transmittance.

description: Domestic or intimate partner violence among African immigrant populations in Western communities, particularly Canada, remains an overlooked public health issue. African immigrant women face compounded challenges, including social isolation, language barriers, unemployment, financial dependence, and legal obstacles, increasing their vulnerability to abuse. With the rise in scholarship exploring the incidence and prevalence of domestic violence, the specific experiences of African immigrant women remain underexplored. This qualitative study investigates West African immigrant women's perceptions and experiences of domestic violence in Alberta, Canada, focusing on definitions, coping strategies, and the influence of patriarchy, culture, and immigration on their responses to violence. Using a Radical feminist, intersectional and Gender Relations Theory in the African Context, the study examines the ways in which power and resources are distributed between men and women in society, while also acknowledging how the power imbalances compounded by culture, patriarchal ideologies, structure, racial, and immigration factors, shape these women's vulnerability to partner violence. Thematic analysis of semi-structured interviews with six participants reveals that domestic violence is often defined as extreme, life-threatening incidents, with most non-physical violence under-recognized. Culturally influenced coping strategies and preferences for informal support services were common. The study underscores the need for culturally responsive interventions and policies to better support African immigrant women in abusive situations. This research aims to inform practitioners, policymakers, and agencies working with West African immigrant women, highlighting the importance of understanding these women’s unique experiences. The goal is to foster the development of culturally responsive programs and services that address the complexities of domestic violence among this population.

description: Mongolian oak (Quercus mongolica) is an important timber species in northeast China, but overdeveloped lateral branches during the seedling stage often result in poor plant architecture and reduce the growth potential. Strigolactones (SLs) were proposed to play an important role in plant architecture by inhibiting the growth of lateral branches; however, there is no knowledge on the strigolactone effects in Mongolian oak. In this study, 0.3, 3, 10, and 30 mg/L of GR24 (analogue of SLs) and 1 mg/L Thidiazuron (TDZ) were applied to Mongolian oak seedlings by the lanolin method. All GR24 treatments significantly reduced the number and biomass of lateral branches; in addition, the length increment of lateral branches was decreased by 3, 10 and 30 mg/L GR24. In addition, the auxin content in lateral branches was significantly increased by the 10 mg/L GR24 treatment, which might be one of the main reasons for the inhibition of lateral branch growth. Increased sucrose content in apex, combined with a decrease of sucrose content in lateral branches, further demonstrated the important role of GR24 in inhibiting lateral branch growth.

description: Quantum biology is an exciting and broad field that tries to explain biological phenomena that cannot be treated via classical approaches. One interesting area of this blooming field is magnetoreception, the ability of biological systems to sense and use the Earth’s magnetic field for navigation and other functions. It is important to have a deep understanding of the mechanisms behind magnetoreception both for its fundamental interest and because of potential technological applications such as bio-inspired magnetosensors. Several models have been developed to explain magnetoreception in biological systems, and the most prominent one among them is the radical-pair mechanism (RPM), which is based on the quantum dynamics of electron and nuclear spins in pairs of radical molecules. The premier candidate for magnetoreception based on the RPM involves the protein cryptochrome. In this process, blue light triggers an electron transfer between flavin adenine dinucleotide (FAD) and a tryptophan triad, leading to the formation of a radical pair. While cryptochrome has historically been the main candidate for RPM magnetoreception, recent experimental studies in vivo and in vitro suggest that FAD alone might also act as a biological magnetosensor. For further evaluation of these results, a detailed theoretical model for the observed magnetic field effects (MFEs) on FAD is needed. Previous models of FAD’s photochemistry under magnetic fields were based on semi-classical approaches. In this thesis, we develop a detailed quantum theoretical model that predicts the MFEs on the photochemistry of FAD for all magnetic field magnitudes. Our quantum theoretical model for the RPM in FAD incorporates Zeeman, hyperfine, and exchange interactions, with the exchange interaction depending on the distance between the radicals. We used existing molecular dynamics (MD) simulations to determine the dynamic distances between the radicals in FAD over time, which we then integrated into a quantum master equation to calculate the spin dynamics under different magnitudes of magnetic fields. This quantum-based model, in contrast to previous semi-classical approaches which were limited to only low and high magnetic fields, can predict the full magnetic field dependence of MFEs. Our theoretical results of the MFEs on FAD’s photochemistry presented in this thesis are in quantitative agreement with experimental results on the transient absorption of this molecule at physiological pH values in the absence and presence of an external magnetic field.
Quantum gates implementations in the separated ion-traps by fast laser pulses

description: An approach is proposed to implement the universal quantum gates between the ions confined individually in the separated traps. Instead of the typical adiabatic operations, performed for manipulating the ion-ion coupling, here the switchable couplings between ions are implemented non-adiabatically by using the fast laser pulses. Consequently, the desirable quantum gates between the ions could be implemented by using only a series of laser pulses. The proposal may be conveniently generalized to the quantum computation with the scalable ion-traps.

Neutrino Mass Model in the Context of $\boldsymbol{Δ(54) \otimes Z_2\otimes Z_3 \otimes Z_4}$ Flavor Symmetries with Inverse Seesaw Mechanism

description: Our analysis involves enhancing the $Δ(54)$ flavor symmetry model with Inverse Seesaw mechanism along with two SM Higgs through the incorporation of distinct flavons. Additionally, we introduce supplementary $Z_2\otimes Z_3 \otimes Z_4$ symmetries to eliminate any undesirable components within our investigation. The exact tri-bimaximal neutrino mixing pattern undergoes a deviation as a result of the incorporation of extra flavons, leading to the emergence of a non-zero reactor angle $θ_{13}$ that aligns with the latest experimental findings. It was found that for our model the atmospheric oscillation parameter occupies the lower octant for normal hierarchy case. We also examine the parameter space of the model for normal hierarchy to explore the Dirac CP ($δ_{CP}$), Jarlskog invariant parameter ($J$) and the Neutrinoless double-beta decay parameter ($m_{ββ}$) and found it in agreement with the neutrino latest data. Hence our model may be testable in the future neutrino experiments.

description: Introduction: Impaired empathy is one of the major dysfunctions commonly found in patients with schizophrenia, with alexithymia being one possible underlying factor. Schizotypy represents a set of psychotic-like manifestations, investigation of which may contribute to our understanding of psychosis while minimising the confounding effects of illness chronicity and medication exposure. Few studies have specifically examined the associations among alexithymia, empathy and schizotypy. Methods: We investigated the relationships among alexithymia, empathy and schizotypy in college students using network analysis. The Interpersonal Reactivity Index (IRI), Toronto Alexithymia Scale (TAS), and Chapman Psychosis-Proneness scales were captured, and network based on the subscales were estimated in 552 participants. Strength, closeness and betweenness of nodes were calculated to measure the centrality. Results: Network analyses revealed a pattern connecting alexithymia with empathy and schizotypy. Negative connections between empathy and physical/social anhedonia and positive edges linking alexithymia with empathy and social anhedonia were observed. Conclusions: Network constructed in the study demonstrated alexithymia’s role in empathic deficits. Our findings highlighted the connections between components of empathy, alexithymia and schizotypy.

description: Intravascular polarimetry with catheter-based polarization-sensitive optical coherence tomography (PS-OCT) complements the high-resolution structural tomograms of OCT with morphological contrast available through polarimetry. Its clinical translation has been complicated by the need for modification of conventional OCT hardware to enable polarimetric measurements. Here, we present a signal processing method to reconstruct polarization properties of tissue from measurements with a single input polarization state, bypassing the need for modulation or multiplexing of input states. Our method relies on a polarization symmetry intrinsic to round-trip measurements and uses the residual spectral variation of the polarization states incident on the tissue to avoid measurement ambiguities. We demonstrate depth-resolved birefringence and optic axis orientation maps reconstructed from in-vivo data of human coronary arteries. We validate our method through comparison with conventional dual-input state measurements and find a mean cumulative retardance error of 13.2deg without observable bias. The 95% limit of agreement between depth-resolved birefringence is 2.80 x 10^(-4), which is less than the agreement between two repeat pullbacks of conventional PS-OCT (3.14 x 10^(-4)), indicating that the two methods can be used interchangeably. The hardware simplification arising from using a single input state may be decisive in realizing the potential of polarimetric measurements for assessing coronary atherosclerosis in clinical practice.
