description: We consider spin dynamics for implementation in an atomistic framework and we address the feasibility of capturing processes in the femtosecond regime by inclusion of moment of inertia. In the spirit of an {\it s-d} -like interaction between the magnetization and electron spin, we derive a generalized equation of motion for the magnetization dynamics in the semi-classical limit, which is non-local in both space and time. Using this result we retain a generalized Landau-Lifshitz-Gilbert equation, also including the moment of inertia, and demonstrate how the exchange interaction, damping, and moment of inertia, all can be calculated from first principles.

Figure S1. Experimental setup for crouch walking. Participants walked on a split-belt treadmill with their silhouette projected onto an anteriorly placed screen. Their objective was to avoid collisions between their silhouette and a virtual ceiling, which was set to 93% of their standing height. Real-time motion-tracking and visual feedback was implemented in a custom program developed with the openFrameworks open-source C++ toolkit, using data from a motion sensing device (Xbox Kinect, Microsoft, WA, USA), situated behind the participant.

description: Metabolic cost minimization is thought to underscore the neural control of locomotion. Yet, avoiding high muscle activation, a cause of fatigue, often outperforms energy minimization in computational predictions of human gait. Discerning the relative importance of these criteria in human walking has proved elusive, in part, because they have not been empirically decoupled. Here, we explicitly decouple whole-body metabolic cost and ‘fatigue-like' muscle activation costs (estimated from electromyography) by pitting them against one another using two distinct gait tasks. When experiencing these competing costs, participants (n = 10) chose the task that avoided overburdening muscles (fatigue avoidance) at the expense of higher metabolic power (p < 0.05). Muscle volume-normalized activation more closely models energy use and was also minimized by the participants' decision (p < 0.05), demonstrating that muscle activation was, at best, an inaccurate signal for metabolic energy. Energy minimization was only observed when there was no adverse effect on muscle activation costs. By decoupling whole-body metabolic and muscle activation costs, we provide among the first empirical evidence of humans embracing non-energetic optimality in favour of a clearly defined neuromuscular objective. This finding indicates that local muscle fatigue and effort may well be key factors dictating human walking behaviour and its evolution.

description: Providing forecasts for ultra-long time series plays a vital role in various activities, such as investment decisions, industrial production arrangements, and farm management. This paper develops a novel distributed forecasting framework to tackle challenges associated with forecasting ultra-long time series by utilizing the industrystandard MapReduce framework. The proposed model combination approach facilitates distributed time series forecasting by combining the local estimators of ARIMA (AutoRegressive Integrated Moving Average) models delivered from worker nodes and minimizing a global loss function. In this way, instead of unrealistically assuming the data generating process (DGP) of an ultra-long time series stays invariant, we make assumptions only on the DGP of subseries spanning shorter time periods. We investigate the performance of the proposed distributed ARIMA models on an electricity demand dataset. Compared to ARIMA models, our approach results in significantly improved forecasting accuracy and computational efficiency both in point forecasts and prediction intervals, especially for longer forecast horizons. Moreover, we explore some potential factors that may affect the forecasting performance of our approach.

Acid rock drainage remediation with Bear River clinoptilolite in a slurry bubble column
Creators: name: Xu, Wanjing
Publisher: name: University of British Columbia
Year: 2013

description: Clinoptilolite, a natural zeolite, is capable of removing heavy metals from acid rock drainage (ARD). However, previous studies have predominantly been on artificial solutions, with no previous work on sorbent regeneration. This study investigated a novel process for capturing ARD and regenerating clinoptilolite based on a slurry bubble column (SBC) for enhanced mass transfer. Uptake tests were performed with natural ARD and various sorbent particle sizes from 300 to 1400 μm in average diameter, superficial gas velocity from 0.08 to 0.23 m/s, initial aqueous pH from 2 to 6, Zn concentrations from 15 to 215 ppm and sorbent/solution ratio from 25 to 400 g/kg to test zinc uptake. To obtain favorable regeneration, zinc in loaded clinoptilolite was displaced by NaCl as regenerant. Regenerant concentrations from 10 to 40 g/kg, regenerant/sorbent ratios from 100 to 400 g/kg, particle sizes from 300 to 1400 μm, and initial regenerant pH from 2 to 6 were tested to find suitable regeneration conditions. To test the long-term viability of clinoptilolite sorbent, repeated capture-regeneration cycles were tested. It was shown that NaCl regenerant could be reused to minimize waste volume. Three removal-only cycles after 10 full cycles continuously decreased the accumulated zinc in the clinoptilolite, allowing the uptake capacity to be almost fully recovered. When 10 full cycles were tested after three removal stages, results were similar to those for the first 10 cycles. Only one-quarter of the regenerant was required to achieve a similar total zinc uptake when reused NaCl solution was utilized. During the remediation, dealumination of clinoptilolite was observed, under certain circumstances. Increased Al in the aqueous phase led to co-precipitation of Zn-Al colloid, enhanced by abundant sulfate in solution. The unit zinc uptake of the Al colloid was much higher than that of the raw clinoptilolite. Adsorption isotherms were fitted to the Langmuir model, and the overall aqueous species and surface uptake were explored by the PHREEQC model. The cyclic capture/regeneration process is promising that further development work is warranted.

description: Using dynamical-mean-field theory for clusters, we study the two-dimensional Hubbard model in which electrons are coupled with the orthorhombic lattice distortions through the modulation in the hopping matrix. Instability towards spontaneous symmetry breaking from a tetragonal symmetric phase to an orthorhombic distorted phase is examined as a function of doping and interaction strength. A very strong instability is found in the underdoped pseudogap regime when the interaction strength is large enough to yield the Mott insulating phase at half filling. The symmetry breaking accompanies the recovery of quasiparticle weights along one of the two antinodal directions, leading to the characteristic Fermi arc reconnection. We discuss the implications of our results to the fourfold symmetry breaking reported in systems where the underlying crystal does not have any structural anisotropy.

description: Jet momentum balance measurements, such as those recently performed by the CMS collaboration, provide an opportunity to quantify the energy transferred from a parton shower to the underlying medium in heavy-ion collisions. Specifically, I argue that the Cooper-Frye freezeout distribution associated with the energy and momentum deposited by the parton shower is controlled to a significant extent by the distribution of the underlying bulk matter and independent of the details of how deposited energy is redistributed in the medium, which is largely determined by transport coefficients such as shear viscosity. Thus by matching the distribution of momentum associated with the secondary jet in such measurements to the thermal distribution of the underlying medium, one can obtain a model independent estimate on the amount of parton shower energy deposited.

description: Perturbation of FRW spacetime is carried out in NP formalism. The equation governing the scalar, vector and tensor modes take on a very simple and transparent form. All of them can be combined in one master equation for all helicities. The solutions for the closed, flat and open FRW are analytic continuation of the same functions, so only the solutions in the closed model are described. The scalar equation is the same as that of the conformally coupled massless Klein-Gordon field, the vectorial ones are the same as Maxwell equations, and the tensorial ones are for spin-2 fields. The corresponding eigen-functions are all determined, and in particular, the Green's function and the Lienard-Wiechert type potential also solved. These solutions reduce to the familiar form in flat space.

description: We investigated the effects of ovarian hormone depletion and chronic intermittent hypoxia (CIH) on blood pressure and ΔFosB staining in central autonomic regions. Our findings indicate that ovariectomy (OVX) and CIH have independent effects on blood pressure and produce region-specific changes in ΔFosB staining in the central autonomic regions associated with hypertension. This suggests that the effects of CIH and OVX on ΔFosB staining and hypertension are not additive.
Secure Compute-and-Forward in a Bidirectional Relay

description: We consider the basic bidirectional relaying problem, in which two users in a wireless network wish to exchange messages through an intermediate relay node. In the compute-and-forward strategy, the relay computes a function of the two messages using the naturally-occurring sum of symbols simultaneously transmitted by user nodes in a Gaussian multiple access (MAC) channel, and the computed function value is forwarded to the user nodes in an ensuing broadcast phase. In this paper, we study the problem under an additional security constraint, which requires that each user's message be kept secure from the relay. We consider two types of security constraints: perfect secrecy, in which the MAC channel output seen by the relay is independent of each user's message; and strong secrecy, which is a form of asymptotic independence. We propose a coding scheme based on nested lattices, the main feature of which is that given a pair of nested lattices that satisfy certain "goodness" properties, we can explicitly specify probability distributions for randomization at the encoders to achieve the desired security criteria. In particular, our coding scheme guarantees perfect or strong secrecy even in the absence of channel noise. The noise in the channel only affects reliability of computation at the relay, and for Gaussian noise, we derive achievable rates for reliable and secure computation. We also present an application of our methods to the multi-hop line network in which a source needs to transmit messages to a destination through a series of intermediate relays.

The dispersing action of polysaccharides in oil sand slurries
Creators: name: Arinaitwe, Esau
Publisher: name: University of British Columbia
Year: 2013

description: Six carboxymethyl celluloses (CMC) of different degrees of substitution, molecular weights, and molecular weight distributions (MWDs) were researched as dispersants of oil sand slurries. The molecular weights and MWDs were determined by analytical ultracentrifugation. Viscometric studies on dilute solutions indicated semi-flexible, random coiling behavior of the polymers assuming an extended conformation in distilled water and coiled conformation in a dilute sodium chloride solution. It was found that the ionic strength, rather than pH or temperature, had the strongest effect on the intrinsic viscosity and conformation of CMC. Calculations of the persistence length and expansion factors of the polymers showed that the lowest molecular weight CMC was most flexible among the tested samples. As rheological and sedimentation tests showed, addition of CMC stabilized oil sand slurries towards aggregation and settling. All the polymers dispersed oil sand slurries by adsorbing on the solid particles and preventing mineral–mineral interactions. The molecular weight of the polymers was a more important factor than the degree of substitution in dispersing the slurries. The role of CMC was also to enhance the liberation of bitumen from solids. This role was analyzed through contact angle measurements in which it was demonstrated that all the CMC samples accelerated bitumen displacement and detachment from the illite surface. The CMC sample of the lowest molecular weight was found to be most effective in promoting bitumen displacement from the illite surface, and this action was attributed to the small effective size and high flexibility of the chain, which allowed the polymer to very closely approach the three-phase point of contact between the mineral, water, and bitumen. Wettability studies also revealed that CMC interacted very weakly with bitumen and did not permanently change the natural hydrophobicity of bitumen. Since a good rheological dispersant should not render bitumen hydrophilic and prevent bitumen extraction, the weak wetting action of CMC at the bitumen-solution interface is actually highly desirable. Overall, this dissertation demonstrated that CMC could play a significant role in improving the processability of low-grade oil sand ores, particularly since the polymer was also shown to be effective at neutral pH and low temperature.

description: We present an effective medium theory that includes bending as well as stretching forces, and we use it to calculate mechanical response of a diluted filamentous triangular lattice. In this lattice, bonds are central-force springs, and there are bending forces between neighboring bonds on the same filament. We investigate the diluted lattice in which each bond is present with a probability $p$. We find a rigidity threshold $p_b$ which has the same value for all positive bending rigidity and a crossover characterizing bending-, stretching-, and bend-stretch coupled elastic regimes controlled by the central-force rigidity percolation point at $p_{\textrm{CF}} \simeq 2/3$ of the lattice when fiber bending rigidity vanishes.

We show that, when hydrodynamical interactions are included, the polymer presents directional motion which depends on the phase differences of the external force applied along the chain. Moreover, the velocity shows a maximum as a function of the frequency. We discuss the relevance of all these results in light of recent nanotechnology experiments.

Investigating the role of Indoleamine 2,3 dioxygenase in Huntington disease
Creators: name: Mazarei, Gelareh
Publisher: name: University of British Columbia
Year: 2013

description: The striatum is predominantly affected in Huntington disease (HD). To address this selective degeneration, we previously studied the gene expression profile in mouse brain and compared the striatum to other brain regions to identify novel striatal-enriched genes. One identified gene was Indoleamine 2,3 dioxygenase (Ido1), the first and the rate-limiting enzyme of the kynurenine pathway (KP), which was differentially expressed in the striatum of YAC128 mouse model of HD. KP leads to the production of both neuroprotective and neurotoxic metabolites, the imbalance of which has been implicated in several neurodegenerative disorders. This PhD thesis initially focuses on the age-dependent changes of the KP in YAC128 mice with a main focus on Ido1 expression and activity. I was able to demonstrate a chronic induction of Ido1 expression and activity in the striatum of YAC128 mice, which correlated with different substrate or product levels during the course of the disease. Using a liquid chromatography mass spectrometry method, I was also able to identify changes in the downstream metabolites, which seemed to follow a biphasic pattern where neurotoxic metabolites were reduced in presymptomatic mice and increased in symptomatic mice. We propose that the striatal-specfic induction of Ido1 and downstream KP alterations suggest involvement in HD pathogenesis, and should be taken into account in future therapeutic developments for HD. To follow up, this thesis project also assesses the sensitivity of brain to NMDA-mediated excitotoxicity in the absence of Ido1 expression under in vivo and ex vivo settings. I was able to demonstrate decreased sensitivity to NMDA receptor-mediated neurotoxicity in the brain of Ido1 constitutive null mice compared to that of WT. These data suggest that lack of Ido1 expression in vivo provides protection against NMDA-receptor-mediated excitotoxic stress, a well-described mechanism in HD pathogenesis.

description: Siadenoviruses have been detected in wild and captive birds worldwide. Only nine siadenoviruses have been fully sequenced; however, partial sequences for 30 others, many of these from wild Australian birds, are also described. Some siadenoviruses, e.g., the turkey siadenovirus A, can cause disease; however, most cause subclinical infections. An example of a siadenovirus causing predominately subclinical infections is psittacine siadenovirus 2, proposed name psittacine siadenovirus F (PsSiAdV-F), which is enzootic in the captive breeding population of the critically endangered orange-bellied parrot (OBP, Neophema chrysogaster). Here, we have fully characterised PsSiAdV-F from an OBP. The PsSiAdV-F genome is 25,392 bp in length and contained 25 putative genes. The genome architecture of PsSiAdV-F exhibited characteristics similar to members within the genus Siadenovirus; however, the novel PsSiAdV-F genome was highly divergent, showing highest and lowest sequence similarity to skua siadenovirus A (57.1%) and psittacine siadenovirus D (31.1%), respectively. Subsequent phylogenetic analyses of the novel PsSiAdV-F genome positioned the virus into a phylogenetically distinct sub-clade with all other siadenoviruses and did not show any obvious close evolutionary relationship. Importantly, the resulted tress continually demonstrated that novel PsSiAdV-F evolved prior to all known members except the frog siadenovirus A in the evolution and possibly the ancestor of the avian siadenoviruses. To date, PsSiAdV-F has not been detected in wild parrots, so further studies screening PsSiAdV-F in wild Australian parrots and generating whole genome sequences of siadenoviruses of Australian native passerine species is recommended to fill the siadenovirus evolutionary gaps.
title: DEPRECATED: EXPLORATION OF RELEVANCE EFFECTS IN REASONING
Creators: name: VENN, SIMON FRANCIS
Publisher: name: University of Plymouth
Year: 2003

description: The study examines possible underlying mechanisms that may be responsible for generally observed biased response patterns in two conditional reasoning tasks: the Wason selection task and the conditional inference evaluation task. It is proposed that memory processes that may account for priming phenomenon, may also account for the phenomena of matching bias and double-negation effects in reasoning. A new mental activation model is proposed, based on distributed theories of memory, which models relevance effects of the problem materials by way of a simple algorithm. The model is seen to parsimoniously predict previous general response patterns found using the two reasoning tasks and makes unusual predictions concerning the size of the concepts used in the reasoning problems. The findings show that matching bias can occur between materials that do not lexically match but correlate on a semantic basis, which clarifies a previously uncertain area in the literature. It is also shown that previously deemed 'irrelevant' or mismatching cards on the selection task can interfere with the perceived relevance of matching cards if they are semantically related. The findings also show a weak but significant effect of concept size on matching bias in the inference task, supporting the proposed mental activation model. Issues concerning the notion of relevance perceptions being measured by particular response choices are raised with respect to both the selection and inference tasks.

description: This paper studies the instrument identification power for the average treatment effect (ATE) in partially identified binary outcome models with an endogenous binary treatment. We propose a novel approach to measure the instrument identification power by their ability to reduce the width of the ATE bounds. We show that instrument strength, as determined by the extreme values of the conditional propensity score, and its interplays with the degree of endogeneity and the exogenous covariates all play a role in bounding the ATE. We decompose the ATE identification gains into a sequence of measurable components, and construct a standardized quantitative measure for the instrument identification power (IIP). The decomposition and the IIP evaluation are illustrated with finite-sample simulation studies and an empirical example of childbearing and women's labor supply. Our simulations show that the IIP is a useful tool for detecting irrelevant instruments.

description: The objective of this study was to evaluate the influence of a probiotic formula on the production of neuroactive compounds in different parts of the colon in batch culture and in vitro gut simulator experiments. Thirteen lactic acid bacterial strains, belonging to the species Levilactobacillus brevis, Lactiplantibacillus plantarum, Lacticaseibacillus paracasei, Ligilactobacillus salivarius, Streptococcus thermophilus, were characterised for their in vitro ability to produce neurotransmitters. L. brevis P30021 and L. plantarum P30025 were selected based on their capability to produce γ-aminobutyric acid (GABA) and acetylcholine in vitro. A probiotic formulation with potential psychobiotic activity was prepared and tested in a batch culture of human microbiota monitoring the formation of GABA and acetylcholine. Samples of the three colonic tracts were taken from the Simulator of the Human Intestinal Microbiota (SHIME®) evaluating the production of GABA and other neurotransmitters by LC-MS. Short chain fatty acids (SCFA) by GC and microbiota composition by 16S rRNA gene sequencing were also determined. Probiotic supplementation led to the formation of GABA and acetylcholine with a decrease in glutamate concentrations in the in vitro batch fermentation. Production of GABA after the treatment with probiotics was confirmed in the SHIME® short-term experiment. No differences in short-chain fatty acids were observed up to 72 h of fermentation. Different microbiota composition was found in the three different parts of the colon, with a higher abundance of Veillonellaceae in the ascending colon vessels. The probiotic-exposed microbiota showed higher levels of Bacteroides, a gut microbe associated with anti-inflammatory activities and a potential GABA producer. Results demonstrate the impact of the tested probiotic formula on gut microbiota structure and GABA production. In conclusion, the probiotic treatment changed the microbiota composition and increased neuroactive metabolites production, indicating promising potential as psychobiotics, even if further clinical evidence is needed to confirm the effectiveness of these probiotics in improving mental health.

Quantum phase slips in superconducting wires with weak inhomogeneities

description: Quantum phase slips are traditionally considered in diffusive superconducting wires which are assumed homogeneous. We present a definite estimate for the amplitude of phase slips that occur at a weak inhomogeneity in the wire where local resistivity is slightly increased. We model such a weak link as a general coherent conductor and show that the amplitude is dominated by topological part of the action. We argue that such weak links occur naturally in apparently homogeneous wires and adjust the estimate to that case. The fabrication of an artificial weak link would localize phase slips and facilitate a better control of the phase-slip amplitude.

Lattice diffeomorphism invariance

description: We propose a lattice counterpart of diffeomorphism symmetry in the continuum. A functional integral for quantum gravity is regularized on a discrete set of space-time points, with fermionic or bosonic lattice fields. When the space-time points are positioned as discrete points of a continuous manifold, the lattice action can be reformulated in terms of average fields within local cells and lattice derivatives. Lattice diffeomorphism invariance is realized if the action is independent of the positioning of the space-time points. Regular as well as rather irregular lattices are then described by the same action. Lattice diffeomorphism invariance implies that the continuum limit and the quantum effective action are invariant under general coordinate transformations - the basic ingredient for general relativity. In our approach the lattice diffeomorphism invariant actions are formulated without introducing a metric or other geometrical objects as fundamental degrees of freedom. The metric rather arises as the expectation value of a suitable collective field. As examples, we present lattice diffeomorphism invariant actions for a bosonic non-linear sigma-model and lattice spinor gravity.

Subjects: Ski Tourism, Management, Climate Changing, Tourism Business

description: The main problem for the tourism businesses which operate in ski resorts is that their revenue are strictly connected to the cumulative snowfall level. The uncertainty about the snowfall due the climate changing has made this type of business highly risky, for this reason few or no investments are made every year to improve the resorts, the slopes or the lifts; continuing in this way, the resort in few years will face to a loss in competitiveness, thus less tourists, less revenue and less business.The present work purposes to show a possible hedging strategy against the financial problems due to the scarcity of snow: the weather derivatives.Due to the fact that in Italy there are many ski resorts situated at an altitude from 1300m to 2000m, we focus our analysis on Andalo, in Italian Alps and we obtain the estimated prices of a put snow option by applying three different methods proposed in literature.We suggest, finally, the ideal prices for Paganella lift operator in Andalo, showing how the use of weather derivatives may be very helpful in the risk management for ski resort related to snow scarcity events.

description: HSP7C/ HSC70 was identified to be associated with ARL5B via gel-based Peptide Mass Fingerprinting (PMF). A GBP (GFP- binding protein) pull-down was performed using the lysate extracted from MDA-MB-231 cells expressing ARL5B-GFP. The pulled down proteins were separated by SDS-PAGE and silver stained to look for bands that were exclusively predominant in the eluate lane of ARL5B-GFP compared to the GFP control. These bands were then excised, digested with trypsin and subjected to mass spectrometry (MALDI-TOF) based analysis. MALDI generated peaklist were then used for identification of the proteins by PMF using the Mascot server.

description: The poster details the methodology and preliminary findings of an accuracy assessment for sea ice condition predictions. This assessment utilizes Synthetic Aperture Radar (SAR) imagery alongside sea ice drift data modeled by Barents 2.5 v2, and a warping algorithm developed by Anton Korosov and Anna Telegina, available at [https://github.com/nansencenter/sar_image_warping]. It presents an analysis of drift and distortion errors, supplementing these findings with case studies on the predictive behavior of sea ice in marginal ice zones and deformation zones, where more "ductile" types of sea ice are predominant.
Vacuum Structure and the Arrow of Time

description: We find ourselves in an extended era of entropy production. Unlike most other observations, the arrow of time is usually regarded as a constraint on initial conditions. I argue, however, that it primarily constrains the vacuum structure of the theory. I exhibit simple scalar field potentials in which low-entropy initial conditions are not necessary, or not sufficient, for an arrow of time to arise. I argue that the string theory landscape gives rise to an arrow of time independently of the initial entropy, assuming a plausible condition on the lifetime of its metastable vacua. The dynamical resolution of the arrow of time problem arises from the same structural properties of the string landscape that allow it to solve the cosmological constant problem without producing an empty universe, particularly its high dimensionality and the large difference in vacuum energy between neighboring vacua.

Authors: Luca Patrone & ChatGPT

Abstract:This paper explores the concept of Fractal Intelligence, proposing that intelligence, consciousness, and even physical laws exhibit self-organizing, recursive patterns. Drawing from chaos theory, neuroscience, artificial intelligence, and cosmology, we investigate how:

Neural and cognitive processes follow fractal dynamics, optimizing efficiency and adaptability.

Fractal architectures in AI can enhance learning, generalization, and computational efficiency.

The universe itself exhibits fractal geometry, from galactic clusters to quantum structures.

By integrating insights from complex systems and self-organization, we propose that intelligence is not a linear construct but a recursive, multi-scale process shaping both human cognition and artificial intelligence.
