description: The cytoplasmic FMR1-interacting protein 2 (CYFIP2) have diverse molecular functions in neurons, including the regulation of actin polymerization, mRNA translation, and mitochondrial morphology and function. Mutations in the CYFIP2 gene are associated with early-onset epilepsy and neurodevelopmental disorders, while decreases in its protein levels are linked to Alzheimer's disease (AD). Notably, previous research has revealed AD-like phenotypes, such as dendritic spine loss, in the hippocampal CA1 pyramidal neurons of 12-month-old Cyfip2 heterozygous mice but not of age-matched CA1 pyramidal neuron-specific Cyfip2 conditional knock-out (cKO) mice. This study aims to investigate whether dendritic spine loss in Cyfip2 cKO mice is merely delayed compared to Cyfip2 heterozygous mice, and to explore further neuronal phenotypes regulated by CYFIP2 in aged mice. We characterized dendrite and dendritic protrusion morphologies, along with excitatory/inhibitory synapse densities in CA1 pyramidal neurons of 17-month-old Cyfip2 cKO mice. Overall dendritic branching was normal, with a reduction in the length of basal, not apical, dendrites in CA1 pyramidal neurons of Cyfip2 cKO mice. Furthermore, while dendritic protrusion density remained normal, alterations were observed in the length of mushroom spines and the head volume of stubby spines in basal, not apical, dendrites of Cyfip2 cKO mice. Although excitatory synapse density remained unchanged, inhibitory synapse density increased in apical, not basal, dendrites of Cyfip2 cKO mice. Consequently, a cell-autonomous reduction of CYFIP2 appears insufficient to induce dendritic spine loss in CA1 pyramidal neurons of aged mice. However, CYFIP2 is required to maintain normal dendritic length, dendritic protrusion morphology, and inhibitory synapse density.

description: Photometry of the A0 V main-sequence star HD 106797 with AKARI and Gemini/T-ReCS is used to detect excess emission over the expected stellar photospheric emission between 10 and 20 micron, which is best attributed to hot circumstellar debris dust surrounding the star. The temperature of the debris dust is derived as Td ~ 190 K by assuming that the excess emission is approximated by a single temperature blackbody. The derived temperature suggests that the inner radius of the debris disk is ~ 14 AU. The fractional luminosity of the debris disk is 1000 times brighter than that of our own zodiacal cloud. The existence of such a large amount of hot dust around HD 106797 cannot be accounted for by a simple model of the steady state evolution of a debris disk due to collisions, and it is likely that transient events play a significant role. Our data also show a narrow spectral feature between 11 and 12 micron attributable to crystalline silicates, suggesting that dust heating has occurred during the formation and evolution of the debris disk of HD 106797.

description: In organizations are being carried out extensive work processes, activities which vary according to whether why they are made for, but also according to the direct results obtained. One can speak thus, on the one hand, about executive processes, in which human resource acts on and / or uses material, financial and information resources in order to achieve targets and, on the other hand, about managerial processes, in which, a part of human resources (managers: top managers, middle managers, etc..) act on the other party, represented by employees, in order to attract the organization in accomplishing its objectives. În the latest years, that has become the main preoccupation of several researchers: Cohen (1981), Barwise and Perry (1983), Klein et al. (1993) etc.. This research is wanted to highlight types of schemas, which are activated by managerial decision: cognitive or emotional schemas. The study is realized on 160 managers from the railway domain, developing activities at state and private institutions. The working methodology is represented by decisional cognitive targets, which the participants must analyze and solve, adopting a solving strategy and a questionnaire to identify the type of the cognitive schema. We have also underline the fact that there are individual targets, not group targets. The results put into evidence the cognitive schemas accessing, together with an existing saturation of emotional decisional schemas.

Insights into the jamming mechanisms in pressure screening
Creators: name: Villalba Chehab, Miguel E.
Publisher: name: University of British Columbia
Year: 2024

description: The phenomenon of particles jamming in constrictions is a common occurrence in everyday situations. It is also a critical problem in particle separation processes such as pressure screening. The majority of the screening literature has focused on strategies to improve the efficiency of the screening operation but, fundamentally, less is known about the jamming mechanisms. In this thesis, we present four studies which provide insights into the jamming mechanisms in pressure screening. In the first study, we elucidated how jams form locally under idealized conditions. Jams may occur by single-particle bridging or flocculation of the suspension. We demonstrated an intermittency for both bridging and flocculation events which follow a Poisson process. Bridging is primarily related to the number of fibres passing through the slot. Flocculation is related to the time interval whose mean decreases inversely with the square root of concentration. In the second study, we explore a hysteresis which has been observed between the jamming and cleaning cycles in the screen. We speculated that the hysteresis stems from the elastoviscoplastic rheology of the pulp network. Using a model fluid with those characteristics, two different flow states were achieved under the same applied pressure—a signature of hysteresis. Complete jamming of the aperture was shown to occur between suction and flow-reversal. In the third study, we analysed imaging data of jamming near the screen apertures. We demonstrated that variations in the distribution of area fluctuations, deviating from the Gaussian state, result from heightened intermittency—an indication of the onset of jamming. In the fourth study, we performed pilot-scale screening trials where the pressure differential was measured. We confirmed that changes in the fluctuations of pressure indicate the onset of jamming. The minimum rotor speed to maintain operation was found to be related to the ratio of fibre length to slot width. Based on our findings, we suggest fine-tuning of the frequency and duration of pressure pulses to align with the mechanical behaviour of the fibre network. Further studies should focus on understanding the role of changes in the global flow state which may aid in the hosting conditions for jams.

description: Spin properties of two interacting electrons in a quantum dot (QD) embedded in a nanowire with controlled aspect ratio and longitudinal magnetic fields are investigated by using a configuration interaction (CI) method and exact diagonalization (ED) techniques. The developed CI theory based on a three-dimensional (3D) parabolic model provides explicit formulations of the Coulomb matrix elements and allows for straightforward and efficient numerical implementation. Our studies reveal fruitful features of spin singlet-triplet transitions of two electrons confined in a nanowire quantum dot (NWQD), as a consequence of the competing effects of geometry-controlled kinetic energy quantization, the various Coulomb interactions, and spin Zeeman energies. The developed theory is further employed to study the spin phase diagram of two quantum-confined electrons in the regime of "cross over" dimensionality, from quasi-two-dimensional (disk-like) QDs to finite one-dimensional (rod-like) QDs.

description: Using the invariant theory of arc spaces, we find minimal strong generating sets for certain cosets of affine vertex algebras inside free field algebras that are related to classical Howe duality. These results have several applications. First, for any vertex algebra $\mathcal V$, we have a surjective homomorphism of differential algebras $\mathbb{C}[J_{\infty}(X_{\mathcal V})] \rightarrow \text{gr}^F(\mathcal V)$; equivalently, the singular support of $\mathcal V$ is a closed subscheme of the arc space of the associated scheme $X_{\mathcal V}$. We give many new examples of classically free vertex algebras (i.e., this map is an isomorphism), including $L_k(\mathfrak{sp}_{2n})$ for all positive integers $n$ and $k$. We also give new examples where the kernel of this map is nontrivial but is finitely generated as a differential ideal. Next, we prove a coset realization of the subregular ${\mathcal W}$-algebra of $\mathfrak{sl}_n$ at critical level that was previously conjectured by Creutzig, Gao, and the first author. Finally, we give some new level-rank dualities involving affine vertex superalgebras.

description: The intensity of globalisation can be measured through the indicators of export-import to Gross Domestic Product (GDP) ratio, inflow and outflow of foreign direct investment (FDI), investment portfolio and payment made for transfer of technology. The current scenario indicates that the industrial activities have undergone major changes caused by globalisation through progress in communication and information technology (ICT). Consumption of modern technology and rapid changes in the production process from being labour- intensive to capital- intensive has contributed to several issues in labour market. This situation has brought about changes in the composition of the competent labour and increase in demand for skilled labour. This article has the objective to analyse the impact of globalisation on demand for skilled labour, namely, professional and management; and technical and supervisory in the manufacturing sector in Malaysia. Analysis is based on panel data from the Industrial Manufacturing Survey data collected by the Department of Statistics, Malaysia of 1985-2008. Analysis is done on the entire manufacturing sector and six subsectors, namely, manufacturing of sieved petroleum products; manufacturing of valves and electronic tubes and other electronic components; production, processing and preserved meat, fish, fruits, vegetables, oil and fats, manufacturing office equipment, accounting tools and calculators; manufacturing basic chemicals; and manufacturing basic iron based and metal products. Findings of the study demonstrate that FDI has positive and significant impact on the demand for both categories of labour, nonetheless, the economic openness and the number of technological agreements have negative impact.

description: We investigate the consequences of the ambiguity of minimal coupling procedure for Einstein-Cartan gravity with Holst term and fermions. A new insight is provided into the nature and physical relevance of coupling procedures considered hitherto in the context of Ashtekar-Barbero-Immirzi formalism with fermions. The issue of physical effects of the Immirzi parameter in semi--classical theory is reinvestigated. We argue that the conclusive answer to the question of its measurability will not be possible until the more fundamental problem of nonuniqueness of gravity--induced fermion interaction in Einstein-Cartan theory is solved.

description: We develop a transfer operator-based method for the detection of coherent structures and their associated lifespans. Characterising the lifespan of coherent structures allows us to identify dynamically meaningful time windows, which may be associated with transient coherent structures in the localised phase space, as well as with time intervals within which these structures experience fundamental changes, such as merging or separation events. The localised transfer operator approach we pursue allows one to explore the fundamental properties of a dynamical system without full knowledge of the dynamics. The algorithms we develop prove useful not only in the simple case of a periodically driven double well potential model, but also in more complex cases generated using the rotating Boussinesq equations.

description: In this moment, the higher education entities, same as the other companies which are in market, carry on the activity in an extremely dynamic environment. Consequence of dimensions and rapidity of environment changes, the higher education institutions can not make abstraction by the reality which is present and they can not see each change as a distinct event, which can be studied individual for maximize the advantages and minimize the negatives effects which product him. Jim Knight said that: „the change is a present reality in the framework of this the educational institutions must to learn to operate or must to assume the failure risk”. These evolutions impose changes in the way in which the managers understand the institution relation with the market whose they address. Similarly, the requests of higher education reform imposed by the transition at Bologna process impose of universities and in the same times of faculties the remarkable adapt efforts. Therefore, the institutions which supply services must to concentrate by quality, equality between sexes and by the instruction improvement, the development and the valorisation of opportunities for women’s, the basis education to be free and obligatory by childhood. The early education by childhood provides the crucial base for their all education. The study it is based by primary quantitative research method by conclusive-descriptive nature based by the divided plans or transversal research how this is know in specialty literature. The dates collect method has been “face to face” investigation and the research instrument the questionnaire. The quantitative dates processed using SPSS.

description: This paper presents the design and development of a robotic system to give physical assistance to the elderly or people with neurological disorders such as Ataxia or Parkinson's. In particular, we propose using a mobile collaborative robot with an interaction-assistive whole-body interface to help people unable to maintain balance. The robotic system consists of an Omni-directional mobile base, a high-payload robotic arm, and an admittance-type interface acting as a support handle while measuring human-sourced interaction forces. The postural balance of the human body is estimated through the projection of the body Center of Mass (CoM) to the support polygon (SP) representing the quasi-static Center of Pressure (CoP). In response to the interaction forces and the tracking of the human posture, the robot can create assistive forces to restore balance in case of its loss. Otherwise, during normal stance or walking, it will follow the user with minimum/no opposing forces through the generation of coupled arm and base movements. As the balance-restoring strategy, we propose two strategies and evaluate them in a laboratory setting on healthy human participants. Quantitative and qualitative results of a 12-subjects experiment are then illustrated and discussed, comparing the performances of the two strategies and the overall system.

description: The weak temperature dependence of the resistance R(T) of monolayer graphene1-3 indicates an extraordinarily high intrinsic mobility of the charge carriers. Important complications are the presence of mobile scattering centres that strongly modify charge transport, and the presence of strong mesoscopic conductance fluctuations that, in graphene, persist to relatively high temperatures4,5. In this Letter, we investigate the surprisingly varied changes in resistance that we find in graphene flakes as temperature is lowered below 70 K. We propose that these changes in R(T) arise from the temperature dependence of the scattered electron wave interference that causes the resistance fluctuations. Using the field effect transistor configuration, we verify this explanation in detail from measurements of R(T) by tuning to different gate voltages corresponding to particular features of the resistance fluctuations. We propose simple expressions that model R(T) at both low and high charge carrier densities.
The Effect of Trust on International Joint Venture Performance in China

description: The role of trust in international joint venture (IJV) performance has attracted a great deal of attention and trust has been recognized as a crucial factor in achieving both financial and non-financial success of IJVs. This paper examines the role of trust from two perspectives: the inter-organizational level and the interpersonal level, as well as their combinations in influencing the performance of IJVs. The paper develops a model of trust in IJVs, which is used to analyze the determinant factors of trust and the influence of trust on IJV performance. The results confirm that trust improves the performance of IJVs and outstanding performance also enhances the level of trust within firms. Results also reveal that Chinese employees hold less trust toward their foreign co-workers and great communication skills have positive influence on trust building. Furthermore, young employees are more inclined to trust people from different nationalities compared to the elders. Satisfactory level of compensation is not directly related to trust building. The findings provide important implications for communication and relationship building between foreign investors and local partners. Keywords: trust, effect, performance, IJV, China

description: Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has chemotherapeutic potential as a regulator of an extrinsic apoptotic ligand, but its effect as a drug is limited by innate and acquired resistance. Recent findings suggest that an intermediate drug tolerance could mediate acquired resistance, which has made the main obstacle for limited utility of TRAIL as an anti-cancer therapeutics. We propose miRNA-dependent epigenetic modification drives the drug tolerant state in TRAIL-induced drug tolerant (TDT). Transcriptomic analysis revealed miR-29 target gene activation in TDT cells, showing oncogenic signature in lung cancer. Also, the restored TRAIL-sensitivity was associated with miR-29ac and 140-5p expressions, which is known as tumor suppressor by suppressing oncogenic protein RSK2 (p90 ribosomal S6 kinase), further confirmed in patient samples. Moreover, we extended this finding into 119 lung cancer cell lines from public data set, suggesting a significant correlation between TRAIL-sensitivity and RSK2 mRNA expression. Finally, we found that increased RSK2 mRNA is responsible for NF-κB activation, which we previously showed as a key determinant in both innate and acquired TRAIL-resistance. Our findings support further investigation of miR-29ac and -140-5p inhibition to maintain TRAIL-sensitivity and improve the durability of response to TRAIL in lung cancer.

description: Social protection is one of poverty alleviation programs that is conceptualized as a set of public actions to address poverty. The most popular program is cash transfer. In October 2005, Indonesia government made an unpopular policy that removed fuel subsidy. The subsidy was changed to be Unconditional Cash Transfer (UCT) and Conditional Cash Transfer (CCT). This study is preceded for three purposes; they are (i) describing condition of cash transfer program in selected Asian countries; (ii) analyzing factors that affect cash transfer program ineffectively in Central Java; and (iii) analyzing assessment of cash transfer program in Central Java, based on government’s perception. A summary of cash transfer schemes in selected Asian Countries showed that social protection scheme in Asian countries relied on cash transfer. Another concern was about the development of harmonized approach for the identification of poor households. The result of the study showed that reports of public dissatisfaction of cash transfer in some areas indicated that the program might experience problems.

We propose several extensions to the WS-Security standard, including name types, key and random number extensions. The extensions are used to implement existing protocols such as ISO9798, Kerberos or BAN-Lowe. The advantages of using these implementations rather than the existing, binary ones, are inherited from the advantages of using Web service technologies, such as extensibility and end-to-end security across multiple environments that do not support a connection-based communication.

description: The Ryu-Takayanagi formula directly connects quantum entanglement and geometry. Yet the assumption of static geometry lead to an exponentially small mutual information between far-separated disjoint regions, which does not hold in many systems such as free fermion conformal field theories. In this work, we proposed a microscopic model by superimposing entanglement features of an ensemble of random tensor networks of different bond dimensions, which can be mapped to a statistical gravity model consisting of a massive scalar field on a fluctuating background geometry. We propose a machine-learning algorithm that recovers the underlying geometry fluctuation from multi-region entanglement entropy data by modeling the bulk geometry distribution via a generative neural network. To demonstrate its effectiveness, we tested the model on a free fermion system and showed mutual information can be mediated effectively by geometric fluctuation. Remarkably, locality emerged from the learned distribution of bulk geometries, pointing to a local statistical gravity theory in the holographic bulk.

description: From a viewpoint of oblate-prolate symmetry and its breaking, we adopt the quadrupole collective Hamiltonian to study dynamics of triaxial deformation in shape coexistence phenomena. It accommodates the axially symmetric rotor model, the $γ$-unstable model, the rigid triaxial rotor model and an ideal situation for the oblate-prolate shape coexistence as particular cases. Numerical solutions of this model yield a number of interesting suggestions. (1) The relative energy of the excited 0+ state can be a signature of the potential shape along the $γ$ direction. (2) Specific E2 transition probabilities are sensitive to the breaking of the oblate-prolate symmetry. (3) Nuclear rotation may induce the localization of collective wave functions in the ($β, γ$) deformation space.

description: The ring finger protein 113A (RNF113A) serves as an E3 ubiquitin ligase and a subunit of the spliceosome. Mutations in the RNF113A gene are associated with X-linked trichothiodystrophy (TTD). However, the cellular roles of RNF113A remain largely unknown. In this study, we performed transcriptome profiling of RNF113A knockout (KO) HeLa cells using RNA sequencing and revealed the upregulation of NRF2 pathway-associated genes. Further analysis confirmed that the KO of RNF113A promotes nuclear localization of the NRF2 protein and elevates the mRNA levels of NRF2 target genes. RNF113A KO cells showed high levels of intracellular reactive oxygen species (ROS) and decreased resistance to cell death following H2O2 treatment. Additionally, RNF113A KO cells more sensitively formed stress granules (SGs) under arsenite-induced oxidative stress. Moreover, RNF113A KO cells exhibited a decrease in glutathione levels, which could be attributed to a reduction in GLUT1 expression levels, leading to decreased glucose uptake reactions and lower intracellular glucose levels. These alterations potentially caused a reduction in ROS scavenging activity. Taken together, our findings suggest that the loss of RNF113A promotes oxidative stress-mediated activation of the NRF2 pathway, providing novel insights into RNF113A-associated human diseases.

description: The pervasiveness of expectations in economic analysis has created significant discussion on the merits and demerits of the two main expectations formation hypotheses, adaptive and rational expectations. This paper gives concise outlines of the two hypotheses and reviews their respective critiques to assess their validity. We outline that the two hypotheses have essentially been regarded as antitheses of each other in economic discourse. In this discourse, exaggerated theoretical intents and criticisms are evident. Inconsistencies among the advocates of rational expectations are also evident, with many of these inconsistencies manifesting themselves in spirited attempts to defend the hypothesis. In the end rational expectations and adaptive expectations are both based on some historical data and learning from experience. While evidence on the usefulness of the models is mixed, it is concluded that both models are beneficial. The adaptive expectations hypothesis may be considered an ad hoc approach, more appropriate for short-term expedient analysis when data and information are scanty. Rational expectations, being based on broader and longer learning experience and data, may be considered appropriate for more comprehensive and longer-term planning. It remains that the rational expectations hypothesis is not per se a model of expectations formation, but a concept pointing to the need for more systematic modeling.

description: We show that mixing a colloidal gel with larger, non-Brownian grains generates novel flow-switched bistability. Using a combination of confocal microscopy and rheology, we find that prolonged moderate shear results in liquefaction by collapsing the gel into disjoint globules, whereas fast shear gives rise to a yield-stress gel with granular inclusions upon flow cessation. We map out the state diagram of this new `mechanorheological material' with varying granular content and demonstrate that its behavior is also found in separate mixture using different particles and solvents.
Temperature during early development alters morphological, physiological, and molecular phenotypes across temporal scales in Atlantic killifish

description: Anthropogenic climate change is causing rising average temperatures and increased thermal variability across aquatic environments. These impacts may be particularly concerning for early life-stages of fishes as their thermal windows are thought to be narrower than those of adults. However, relatively little is known about how these early-life stages will respond to predicted temperature changes with global warming. Therefore, I investigated the effects of different temperature regimes on early life-stages and how they respond to these environments both acutely and by utilizing developmental plasticity in two subspecies of Fundulus heteroclitus, a topminnow that inhabits intertidal saltmarshes along the Atlantic coast of North America. I generated thermal performance curves (TPC) for development in embryos of two F. heteroclitus subspecies reared at a series of constant temperatures and found evidence consistent with both local adaptation and countergradient variation between the subspecies. I also showed that F. heteroclitus reared at different temperatures had altered hypoxia tolerance and hif1α mRNA transcript abundance, but I observed no change in thermal tolerance. This finding demonstrates that developmental cross-tolerance can occur in F. heteroclitus. However, these differences did not persist at the age of 1 year, highlighting reversible plasticity. I then examined how fluctuating thermal regimes during development affected embryonic and larval phenotypes. I demonstrated development under fluctuating temperatures can alter performance in ways that cannot always be predicted based on performance generated at constant temperatures. Furthermore, I showed the fish reared under fluctuating temperatures had altered growth, thermal tolerance, and hypoxia tolerance, which were associated with long-lasting transcriptomic effects that persisted even in a common environment. However, high thermal variability during development had lasting negative consequences on phenotypes as the result of deleterious plasticity. Taken together, my research demonstrates that F. heteroclitus utilize developmental plasticity as a mechanism to cope with changing temperatures during early development. However, there are limitations to this plasticity which are highlighted in the reversible and deleterious plasticity I detected.

description: Analytic exact expressions for the quasinormal modes of scalar and electromagnetic perturbations around a special class of black holes are found in d\ge3 dimensions. It is shown that, the size of the black hole provides a bound for the angular momentum of the perturbation. Quasinormal modes appear when this bound is fulfilled, otherwise the excitations become purely damped.

description: The construction industry is one of the more important economic activities that contribute towards the economic growth of any nation. The construction industry in Libya faces serious challenges and difficulties due to fast developments and dependence on foreign experts. The current capacity of the Libyan construction industry in order to meet national housing supply needs. Recently, the country is witnessing a new construction boom that will bypass all other construction activity of the past decades. New houses, airports, ports, railways, and roads need to be built and upgraded. Hotels, office buildings and resorts are required to meet the needs of an expanding tourism industry. The main reason for conducting this study was to evaluate which critical success factors are most important in phases of construction projects. This study was in the Wadi Alhaya region in southern part of Libya. A quantitative approach was selected. As conclusion, this paper identifies ten critical success factors that are important and will impact positively on construction projects if they are focused on by all the stakeholders and it can be concluded that the critical success factors found to be most influential in this study could be utilized in future work which examines different situations and environments.

description: Traditionally, alloying and thermal treatment are considered as the main tools for design of new materials. Application of first-principles simulations can significantly accelerate the process of materials design, however, to account for both, multicomponent chemical disorder and finite temperature effects in theoretical simulations is a challenging task. In this work we have trained machine learning interatomic potential to effectively simulate finite temperature elastic properties of multicomponent β-Ti94-xNbxZr6 alloys. Our simulations predict the presence of the elinvar effect for the wide range of temperatures. Importantly, we predict that in a vicinity of dynamical and mechanical instability, the β-Ti94-xNbxZr6 alloys demonstrate strongly non-linear concentration-dependence of elastic moduli, which leads to low values of moduli comparable to that of human bone. Moreover, these alloys demonstrate a strong anisotropy of directional Young's modulus which can be helpful for microstructure tailoring and design of materials with desired elastic properties.

description: Rubric-based admissions are claimed to help make the graduate admissions process more equitable, possibly helping to address the historical and ongoing inequities in the U.S. physics graduate school admissions process that have often excluded applicants from minoritized races, ethnicities, genders, and backgrounds. Yet, no studies have examined whether rubric-based admissions methods represent a fundamental change of the admissions process or simply represent a new tool that achieves the same outcome. To address that, we developed supervised machine learning models of graduate admissions data collected from our department over a seven-year period. During the first four years, our department used a traditional admissions process and switched to a rubric-based process for the following three years, allowing us to compare which parts of the applications were used to drive admissions decisions. We find that faculty focused on applicants' physics GRE scores and grade point averages when making admissions decisions before the implementation of the rubric. While we were able to develop a sufficiently good model whose results we could trust for the data before the implementation of the rubric, we were unable to do so for the data collected after the implementation of the rubric, despite multiple modifications to the algorithms and data such as implementing Tomek Links. Our inability to model the second data set despite being able to model the first combined with model comparison analyses suggests that rubric-based admissions does change the underlying process. These results suggest that rubric-based holistic review is a method that could make the graduate admissions process in physics more equitable.
