description: In this work, we present two new methods for Variational Quantum Circuit (VQC) Process Tomography onto $n$ qubits systems: PT_VQC and U-VQSVD.
 Compared to the state of the art, PT_VQC halves in each run the required amount of qubits for process tomography and decreases the required state initializations from $4^{n}$ to just $2^{n}$, all while ensuring high-fidelity reconstruction of the targeted unitary channel $U$. It is worth noting that, for a fixed reconstruction accuracy, PT_VQC achieves faster convergence per iteration step compared to Quantum Deep Neural Network (QDNN) and tensor network schemes.
 The novel U-VQSVD algorithm utilizes variational singular value decomposition to extract eigenvectors (up to a global phase) and their associated eigenvalues from an unknown unitary representing a general channel. We assess the performance of U-VQSVD by executing an attack on a non-unitary channel Quantum Physical Unclonable Function (QPUF). U-VQSVD outperforms an uninformed impersonation attack (using randomly generated input states) by a factor of 2 to 5, depending on the qubit dimension.
 For the two presented methods, we propose a new approach to calculate the complexity of the displayed VQC, based on what we denote as optimal depth.

description: We introduce a quantum information analysis of vibrational wave functions to understand complex vibrational spectra of molecules with strong anharmonic couplings and vibrational resonances. For this purpose, we define one- and two-modal entropies to guide the identification of strongly coupled vibrational modes and to characterize correlations within modal basis sets. We evaluate these descriptors for multi-configurational vibrational wave functions which we calculate with the n-mode vibrational density matrix renormalization group algorithm. Based on the quantum information measures, we present a vibrational entanglement analysis of the vibrational ground and excited states of CO2, which display strong anharmonic effects due to the symmetry-induced and accidental (near-) degeneracies. We investigate the entanglement signature of the Fermi resonance and discuss the maximally entangled state arising from the two degenerate bending modes.

description: Nella fermentazione alcolica del mosto d'uva con Kl. apiculata, la cicloeximide (acticlione) inibiva parzialmente la formazione della glicerina e clell'acetoina. L'inibizione della formazione della glicerina era parzialmente contrastata dalla L-adrenalina, mentre la DL-etionina e il cortisolo contrastavano quella dell'acetoina. La cicloeximide causava anche un aumento del rendimento in alcole. L'etionina attivava tanto la formazione della glicerina quanto quella dell'acetoina. L'adrenalina non influiva sulla formazione della glicerina, ma inibiva fortemente quella dell'acetoina. In presenza di cortisolo avveniva il contrario. I risultati sono discussi in relazione alla possibilità di variare i rapporti fra i prodotti secondari della fermentazione con l'aiuto di sostanze endogene o esogene ai mosti. Einfluß von Cycloheximid, DL-Aethionin, L-Adrenalin und Cortisol auf die von Kloeckera apiculata verursachte Biosynthese des Glycerin und des Acetoin In der von Kloeckera apiculata verursachten alkoholischen Gärung des Traubenmostes hemmte Cycloheximid (Actidion) die Glyzerin- und Acetoinbildung teilweise. Die Hemmung der Glycerinbildung wurde zum Teil von L-Adrenalin aufgehoben, während DL-Aethionin und Cortisol der Hemmung der Acetoinbildung entgegenwirkten. Cycloheximid verursachte auch eine Zunahme der Alkoholbildung während der Gärung. Die Glyzerin- und Acetoinbildung wurde von DL-Aethionin aktiviert. L-Adrenalin übte keine Wirkung auf die Glyzerinbildung aus, hemmte jedoch die Acetoinbildung. In Anwesenheit von Cortisol erfolgte das Gegenteil. Die Ergebnisse wurden hinsichtlich der Möglichkeit erörtert, die Anteile der sekundären Gärungsprodukte mit Hilfe endogener oder exogener Stoffe zu verändern.

description: Analysis and modelling of genotype x environment x management interactions : application to the sunflower crop (PhD thesis, in French) In sunflower crop, the actual seed yield stagnation results from a singular compensation between genetic progress (+1.3% potential yield/year) and degradation of cultural environments and crop management.
Independently of this progress, Genotype by environment (GxE) interactions lead to highly variable cultivar performance regarding pedo-climatic and management crop conditions. The sudden surge of vegetable oils price in a crop context generally aiming towards extensification may result in original cultivar-environment-management choices. Such context requires to rapidly forecast the ability of each new variety to valorise cropping systems for various conditions.
The main goal of this study was to develop a crop model accounting for GxE interactions. Each genotype was represented by a set of measured parameters that are valid under a wide range of conditions. Two virtual studies were conducted to assess the model adequacy in identifying interesting crop management and to a further point, in assisting crop breeding.

description: Delayed neuropsychiatric sequelae (DNS) are critical complications following acute carbon monoxide (CO) poisoning that can substantially affect the patient’s life. Identifying high-risk patients for developing DNS may improve the quality of follow-up care. To date, the predictive DNS determinants are still controversial. Consequently, this study aimed to construct a practical nomogram for predicting DNS in acute CO-poisoned patients. This retrospective study was conducted on patients with acute CO poisoning admitted to the Tanta University Poison Control Center (TUPCC) from December 2018 to December 2022. Demographic, toxicological, and initial clinical characteristics data, as well as laboratory investigation results, were recorded for the included patients. After acute recovery, patients were followed up for six months and categorized into patients with and without DNS. Out of 174 enrolled patients, 38 (21.8%) developed DNS. The initial Glasgow Coma Scale (GCS), carboxyhemoglobin (COHb) level, CO exposure duration, oxygen saturation, PaCO2, and pulse rate were significantly associated with DNS development by univariate analysis. However, the constructed nomogram based on the multivariable regression analysis included three parameters: duration of CO exposure, COHb level, and GCS with adjusted odd ratios of 1.453 (95% CI: 1.116–1.892), 1.262 (95% CI: 1.126–1.415), and 0.619 (95% CI: 0.486–0.787), respectively. The internal validation of the nomogram exhibited excellent discrimination (area under the curve [AUC] = 0.962), good calibration, and satisfactory decision curve analysis for predicting the DNS probability. The proposed nomogram could be considered a simple, precise, and applicable tool to predict DNS development in acute CO-poisoned patients.

description: We compute the gravitational form factors $A_i$, $D_i$ and $\bar c_i$ of the scalar Yukawa theory using both the light-cone and covariant perturbation theory at the one-loop level. The light-cone formalism provides a potential approach to access these form factors beyond the perturbative regime. However, unlike the covariant formulation, the Poincaré symmetry on the light cone is not manifest. In this work, we use perturbation theory as a benchmark to extract the gravitational form factors from the light-front energy-momentum tensor. By comparing results on and off the light cone, we identify $T^{++}, T^{+a}, T^{+-}, T^{12}$ as the "good currents" that are properly renormalized and can be used to extract the gravitational form factors.

On the contribution of dwarf galaxies to reionization of the Universe

description: We present estimates of the ultraviolet (UV) and Lyman continuum flux density contributed by galaxies of luminosities from $M_{\rm UV}\approx -25$ to $M_{\rm UV}=-4$ at redshifts $5\leq z\leq 10$ using a galaxy formation model that reproduces properties of local dwarf galaxies down to the luminosities of the ultra-faint satellites. We characterize the UV luminosity function (LF) of galaxies and their abundance as a function of the ionizing photon emission rate predicted by our model and present accurate fitting functions describing them. Although the slope of the LF becomes gradually shallower with decreasing luminosity due to feedback-driven outflows, the UV LF predicted by the model remains quite steep at the luminosities $M_{\rm UV}\lesssim -14$. After reionization, the UV LF flattens at $M_{\rm UV}\gtrsim -12$ due to UV heating of intergalactic gas. However, before reionization, the slope of the LF remains steep and approximately constant from $M_{\rm UV}\approx -14$ to $M_{\rm UV}=-4$. We show that for a constant ionizing photon escape fraction the contribution of faint galaxies with $M_{\rm UV}>-14$ to the UV flux and ionizing photon budget is $\approx 40-60\%$ at $z>7$ and decreases to $\approx 20\%$ at $z=6$. Before reionization, even ultra-faint galaxies of $M_{\rm UV}>-10$ contribute $\approx 10-25\%$ of ionizing photons. If the escape fraction increases strongly for fainter galaxies, the contribution of $M_{\rm UV}>-14$ galaxies before reionization increases to $\approx 60-75\%$. Our results imply that dwarf galaxies fainter than $M_{\rm UV}=-14$, beyond the James Webb Space Telescope limit, contribute significantly to the UV flux density and ionizing photon budget before reionization alleviating requirements on the escape fraction of Lyman continuum photons.

description: On 18 May 2024, a superbolide traversed the western part of the Iberian Peninsula, culminating its flight over the Atlantic Ocean and generating significant media attention. This event was caused by a weak carbonaceous meteoroid of 1 m, entering the atmosphere at 40.4 km$\,$s$^{-1}$ with an average slope of 8.5$^\circ$. The luminous phase started at 133 km and ended at an altitude of 54 km. The meteoroid's heliocentric orbit had an inclination of 16.4$^\circ$, a high eccentricity of 0.952, a semi-major axis of 2.4 au, and a short perihelion distance of 0.12 au. The superbolide was recorded by multiple ground-based stations of the Spanish Meteor Network (SPMN) and the European Space Agency (ESA), as well as by the U.S. Government (USG) sensors from space. Due to the absence of observable deceleration, we successfully reconciled satellite radiometric data with a purely dynamic atmospheric flight model, constraining the meteoroid's mass and coherently fitting its velocity profile. Our analysis shows a good agreement with the radiant and velocity data reported by the Center for Near-Earth Object Studies (CNEOS), with a deviation of 0.56$^\circ$ and 0.1 km$\,$s$^{-1}$, respectively. The presence of detached fragments in the lower part of the luminous trajectory suggests that the meteoroid was a polymict carbonaceous chondrite, containing higher-strength macroscopic particles in its interior due to collisional gardening, or a thermally processed C-type asteroid. The orbital elements indicate that the most likely source is the Jupiter-Family Comet (JFC) region, aligning with the SOHO comet family, as its sunskirting orbit is decoupled from Jupiter. This event provides important information to characterize the disruption mechanism of near-Sun objects.

description: In Beeren der Sorten Müller-Thurgau und Silvaner wurde in zwei Vegetations"perioden während des Reifeprozesses neben der Entwicklung des Beerengewichtes, der titrierbaren Säure und des Mostgewichtes die Abscisinsäure (ABS) quantitativ ermittelt. • Nach geringen Werten in der Phase II und III der Beerenentwick1ung nehmen die absoluten ABS-Gehalte und die ABS-Konzentration zu Beginn der Phase IV in Samen und Fruchtfleisch bis zu einem Maximum im September bzw. Oktober zu und sinken im weiteren Verlauf der Beerenreife wieder ab. • Das Absinken der ABS-Werte der Beeren im Freiland kann nicht auf die Wirkung einer kurzen Frostperiode zurückgeführt werden. • Die Höhe und Dauer der ABS-Akkumulation war in beiden Jahren unterschiedlich, die Beeren von Silvaner besaßen in beiden Vegetationsperioden ein höheres ABS-Niveau als die von Müller-Thurgau. • Die kontinuierlich ansteigenden Gehalte an gebundener ABS deuten darauf hin, daß die gebundene ABS weder eine Vorstufe noch ein Folgeprodukt der freien ABS ist. Abscisic acid in ripening grape berries In the berries of the Vitis vinifera cultivars "Müller-Thurgau" and "Silvaner", besides berry weight, titratable acid, and total soluble solids, the changes of the ABA-contents with regard to ripening were investigated during two growing seasons. • Starting with small amounts in phases II and III of the berry development, the absolute ABA-contents (µg/1000 berries or seeds) and the ABA-concentration (ftg/kg) increase in seeds as weil as in pulp up to a maximum at the beginning of phase IV in September and October and decrease during the further development of the berries. • The decrease of the ABA-contents in the berries of field-grown vines is not caused by a short frost period. • The extent and duration of the ABA-accumulation differed slightly in the two years. In both seasons, the ABA-level of the berries was higher in "Silvaner" than in "Müller-Thurgau". • The steady increase of the bound ABA indicates that the bound ABA is neither a precursor nor a following product of the free ABA.

description: In this work, we consider a general gravitational wave detector of gravitational wave interacting with an incoming gravitational wave carrying plus polarization only placed inside a harmonic trap. This model can be well acquainted with the description of a resonant detector of gravitational wave as well. The well known detector-gravitational wave interaction scenario uses the method of a semi classical approach where the detector is treated quantum mechanically but the gravitational wave is considered at a classical level. In our analysis, we use a discrete mode decomposition of the gravitational wave perturbation which results in a Hamiltonian involving the position and momentum operators corresponding to the gravitational wave and the harmonic oscillator. We have then calculated the transition probability for the harmonic oscillator-gravitational wave tensor product state for going from an initial state to some unknown final state. Using the energy flux relation of the gravitational waves, we observe that if we consider the total energy as a combination of the number of gravitons in the initial state of the detector then the transition probability for the resonant absorption case scenario takes the analytical form which is exactly similar to the semi-classical absorption case. In case of the emission scenario, we observe a spontaneous emission of a single graviton which was completely absent in the semi-classical analouge of this model. This therefore gives a direct signature of linearized quantum gravity.

description: Studies on cracking of rachis of grapes have shown th at out of 87 cultivars under study, 16 were prone to it. Berry quality was not affected by the malady. Data on chemical composition of leaves suggested that the abnormality is not due to nutritional imbalance. Risse in Traubenstielen Bei 16 von 87 untersuchten Rebensorten traten mehr oder weniger häufig Längsrisse in den Traubenstielen auf. Die Qualität der Beeren wurde durch die Erkrankung nicht beeinflußt. Aufgrund der Befunde über den Mineralstoffgehalt der Blätter ist zu vermuten, daß die Abnormität nicht durch eine unausgewogene Ernährung, sonde rn durch andere Faktoren verursacht wird.

description: An extensive environmental study, with particular reference to yeasts and yeast-like organisms, was made of the vineyard at Lang Ashton. The results of this microecological survey were obtainecl by using a variety of techniques in which a quantitative estimate was macle of the yeasts and yeast-like organisms. Sampling was carried out at all stages of grape vine cleveopment. Sources of yeasts and yeastlike organisms included all vine parts as well as the soil, air, other plants ancl animal vectors which frequented those sources. Many potential spoilage organisms, e. g. film yeasts, were present but fermenting yeasts (Saccharomyces spp.) were rarely found. Among the microorganisms isolatecl were new unreported species of Trichosporonoides, Saccharomycopsis (synonym of Endomycopsis), Sporobolomyces, Sporidioboltis, Rhodosporiditim, Candida, Nadsonia and Schizosaccharomyces. Other isolates were identified as species within the genera Aureobasidium, Trichosporon, Sporobolomyces, Rhodotorula, Cryptoccus, Metschnikowia, Torulopsis, Candida, Pichia, Hansenula, Kluyveromyces, Saccharomyces and Kloeckera. Mikroökologie der Hefen und hefenähnlichen Organismen aus einem englischen Weinberg Mit Hilfe verschiedener Schätzmethoden wurde die quantitative Verteilung der Hefen und hefenähnlichen Organismen im Weinberg von Long Ashton ermittelt.

Hefen und ähnliche Organismen fanden sich an sämtlichen Teilen der Rebe, im Boden, in der Luft, an anderen Pflanzen sowie an tierischen Überträgern dieses Biotops. Es traten viele potentielle Urheber von Fehlgärungen, z. B. Kahmhefen, auf, während Weinhefen (Saccharomyces spp.) nur selten festgestellt wurden. Unter den isolierten Mikroorganismen befanden sich aus Weinbergen bisher nicht bekannte Arten der Gattungen Trichosporonoides, Saccharomycopsis (syn.

Die Heterosiskreuzungen wiesen ein erheblich besseres Wachstum als die Selbstungsfamilien auf. Auch die Zahl der fruchtenden Sämlinge dieser Kreuzungen war höher. In bezug auf Traubengröße und in einzelnen Fällen auch auf Beerengröße war die Heterosis in den betreffenden Kreuzungen auffallend, wobei der Durchschnittsertrag pro Stock bei den Heterosiskreuzungen (mit Ausnahme von RWV (S1 ) X RWV (S1 )) auffällig höher lag als bei den Selbstungsfamilien. Auch eine frühere Traubenreife konnte in den Heterosiskreuzungen festgestellt werden. Bei Verwendung dieser Methode in der Züchtungspraxis wird man auch bei der Vitis vinifera ohne die Topcross-Methode nicht auskommen können. Dei Fixation des Heterosiseffektes mittels vegetativer Vermehrung wäre ein großer Vorteil. Heterozygotic breeding at Vitis vinifera L. The S1 -offsprings of the "Roter Traminer" (RT) and the "Rotweißer Veltliner" (RWV) were compared with offsprings of crossings between these S1 -families and investigated for heterosis effects. The latter families showed a much better growth than the former ones. The number of the fruit bearing seedlings also was higher in the hybrid offsprings. With regard to the size of the bunches and also, in some cases, to the size of the berries, heterosis was remarkable in the offsprings concerned. Compared to the S1 -offsprings the average yield per vine was considerably higher in the hybrid offsprings (with the exception of RWV [S1] X RWV [S1]). Moreover, an earlier grape maturity could be ascertained in the hybrid offsprings. Besides using this method in grape breeding, the topcross-method also will be necessary. The fixation of the heterosis effect by means of vegetative propagation would be of great value.

description: Stochastic magnetic tunnel junctions (s-MTJ) is a promising component of probabilistic bit (p-bit), which plays a pivotal role in probabilistic computers. For a standard cell structure of the p-bit, s-MTJ is desired to be insensitive to voltage across the junction over several hundred millivolts. In conventional s-MTJs with a reference layer having a fixed magnetization direction, however, the stochastic output significantly varies with the voltage due to spin-transfer torque (STT) acting on the stochastic free layer. In this work, we study a s-MTJ with a "double-free-layer" design theoretically proposed earlier, in which the fixed reference layer of the conventional structure is replaced by another stochastic free layer, effectively mitigating the influence of STT on the stochastic output. We show that the key device property characterized by the ratio of relaxation times between the high- and low-resistance states is one to two orders of magnitude less sensitive to bias voltage variations compared to conventional s-MTJs when the top and bottom free layers are designed to possess the same effective thickness. This work opens a pathway for reliable, nanosecond-operation, high-output, and scalable spintronics-based p-bits.

description: By incorporating inert KCl into the Na$_2$IrO$_3$ + 2CuCl $\to$ Cu$_2$IrO$_3$ + 2NaCl topochemical reaction, we significantly reduced the synthesis temperature of Cu$_2$IrO$_3$ from the 350$^\circ$C reported in previous studies to 170$^\circ$C. This adjustment decreased the Cu/Ir antisite disorder concentration in Cu$_2$IrO$_3$ from $\sim$19$\%$ to $\sim$5$\%$. Furthermore, magnetic susceptibility measurements of the present Cu$_2$IrO$_3$ sample revealed a weak ferromagnetic-like anomaly with hysteresis at a magnetic transition temperature of $\sim$70 K. Our research indicates that the spin-disordered ground state reported in chemically disordered Cu$_2$IrO$_3$ is an extrinsic phenomenon, rather than an intrinsic one, underscoring the pivotal role of synthetic chemistry in understanding the application of Kitaev model to realistic materials.

Assessment

description: Social anxiety disorder is defined by an intense and distressing fear and avoidance of social situations with unfamiliar individuals, particularly those situations that provide the opportunity to be scrutinized (APA, 2013). A core feature of social anxiety involves fears of negative evaluation (FNE) and fears of positive evaluation (FPE). These core features are most commonly assessed using the Fear of Positive Evaluation Scale (FPES; Weeks et al., 2008) and the Brief Fear of Negative Evaluation Scale (BFNE; Leary, 1983). A robust line of evidence supports the psychometric properties of these measures when administered to adults; we know little about these measures’ properties when administered to adolescents. This study tests links between multi-informant reports on the FPES and BFNE and adolescents’ behavior within interactions with unfamiliar peers. We recruited 105 adolescents for the study. Adolescents completed a battery of measures examining their thoughts and behaviors and then completed social interaction tasks with a confederate. Parents completed a battery of questionnaires about themselves and their adolescent’s thoughts and behaviors. Both parents and adolescents provide reports about adolescents’ fears of evaluation that relate to adolescents’ observed behavior within interactions with unfamiliar peers. However, relative to parents’ reports, adolescents’ reports across FNE and FPE more robustly relate to observed behavior within these interactions. Further, across both informants and evaluative domains, FPE provide incrementally valuable information when understanding how adolescents behave within interactions with unfamiliar peers.

description: This study examined Asian and White bisexual women’s sexual orientation disclosure to their female friends, including the relation of disclosure to racial and sexual identity, individual well-being, and friendship quality. It was hypothesized that Asian bisexual women would be less likely to disclose their sexual minority status to Asian friends and more likely to friends of differing racial/ethnic identities, as well as less likely to monosexual friends. Also, sexual identity disclosure for all participants, regardless of race/ethnicity, was expected to be positively associated with both friendship quality and individual well-being. A sample of 324 bisexual women completed measures focused on their demographic information, personal self-esteem, self-authenticity, satisfaction with life, and perceived social support, as well as their interpersonal level of outness, validation, trust, intimacy, and overall friendship. Results from multilevel models indicated that participant race/ethnicity interacted with friend race/ethnicity and sexual orientation in predicting disclosure: Asian bisexual women’s disclosure level was higher with same-race/ethnicity friends but unrelated to whether the friend was LGQ. In contrast, White bisexual women’s disclosure level was unrelated to similarity of the friend’s race/ethnicity but was lower among friends viewed as LGQ. Disclosure of bisexuality was positively associated with friendship quality at both the within-person and between-person levels, and was positively related to self-esteem, life satisfaction, and perceptions of social support from friends.

description: The assimilation of the indigenous to minors represented a doctrinal deviation from the traditional category of miserable. While the conditions of miserable or rustic were generally taken to be natural conditions that could not be easily changed, the condition of minor was considered to be transitory and to lead to an end with emancipation.

description: Typical mechanisms to extract energies from a rotating black hole are the Blandford-Znajek process and the Penrose process. The Penrose process requires a special condition that is difficult to occur in common astrophysical situations. However, the magnetic Penrose process (MPP) does not require such a special condition, and can produce ultra-high energy cosmic rays. When neutrons decay near a rotating black hole, the MPP efficiency of the produced proton is maximized. The supermassive black hole in Sagittarius A* (Sgr A*) is likely to have a radiatively inefficient accretion flow that is hot enough to produce neutrons by nuclear reactions, which can be subsequently accelerated to high-energy by the MPP. We calculate the production rate of accelerated protons from the Sgr A* to estimated the gamma-ray flux at Earth produced by these accelerated protons and the flux of the accelerated protons themselves transported from Sgr A* to Earth. We find that these very high-energy gamma rays ($E_γ\gtrsim10\,\mathrm{TeV}$) amount to a significant fraction of the flux of the gamma-ray from the HESS J1745-290 and the central molecular zone around $100\,\mathrm{TeV}$. The accelerated proton flux, when the dimensionless spin parameter $a_{*}=0.5$ and the magnetic field strength in the vicinity of the black hole $B_{0}=100\,\mathrm{G}$, is about $1.6-4.1\%$ of the cosmic ray proton flux from KASCADE experiment at about $1\,\mathrm{PeV}$. Due to the finite decay time of neutrons which need to be transported from the accretion flow to the acceleration zone, our acceleration model can operate only around black holes with mass not much greater than $\sim10^8\,M_\odot$.

description: Real-world non-autonomous systems are open, out-of-equilibrium systems that evolve in and are driven by temporally varying environments. Such systems can show multiple timescale and transient dynamics together with transitions to very different and, at times, even disastrous dynamical regimes. Since such critical transitions disrupt the systems' intended or desired functionality, it is crucial to understand the underlying mechanisms, to identify precursors of such transitions and to reliably detect them in time series of suitable system observables to enable forecasts. This review critically assesses the various steps of investigation involved in time-series-analysis-based detection of critical transitions in real-world non-autonomous systems: from the data recording to evaluating the reliability of offline and online detections. It will highlight pros and cons to stimulate further developments, which would be necessary to advance understanding and forecasting nonlinear behavior such as critical transitions in complex systems.

description: The purpose of this study was comparative characterization of psycho-physiological features of elite athletes - the representatives of the climbing on the complexity, speed and climbers. The study included 26 elite athletes (age 19-22 years). It is shown that athletes much more accurately reproduce a time interval of 30 seconds, compared with a time interval of 1 minute. Revealed that the climbers (climbing speed) and in some cases, climbers (climbing difficulty)show significantly better results on tests of reaction rate under difficult conditions. Found higher rates of mobility and strength of nervous processes in rock climbers compared with climbers. This fact is related to the specific training and competitive activities of climbing, which requires a global concentration or under conditions of maximum circa power voltage.

description: In the realm of personalized recommender systems, the challenge of adapting to evolving user preferences and the continuous influx of new users and items is paramount. Conventional models, typically reliant on a static training-test approach, struggle to keep pace with these dynamic demands. Streaming recommendation, particularly through continual graph learning, has emerged as a novel solution. However, existing methods in this area either rely on historical data replay, which is increasingly impractical due to stringent data privacy regulations; or are inability to effectively address the over-stability issue; or depend on model-isolation and expansion strategies. To tackle these difficulties, we present GPT4Rec, a Graph Prompt Tuning method for streaming Recommendation. Given the evolving user-item interaction graph, GPT4Rec first disentangles the graph patterns into multiple views. After isolating specific interaction patterns and relationships in different views, GPT4Rec utilizes lightweight graph prompts to efficiently guide the model across varying interaction patterns within the user-item graph. Firstly, node-level prompts are employed to instruct the model to adapt to changes in the attributes or properties of individual nodes within the graph. Secondly, structure-level prompts guide the model in adapting to broader patterns of connectivity and relationships within the graph. Finally, view-level prompts are innovatively designed to facilitate the aggregation of information from multiple disentangled views. These prompt designs allow GPT4Rec to synthesize a comprehensive understanding of the graph, ensuring that all vital aspects of the user-item interactions are considered and effectively integrated. Experiments on four diverse real-world datasets demonstrate the effectiveness and efficiency of our proposal.

description: We introduce an efficient variational hybrid quantum-classical algorithm designed for solving Caputo time-fractional partial differential equations. Our method employs an iterable cost function incorporating a linear combination of overlap history states. The proposed algorithm is not only efficient in time complexity, but has lower memory costs compared to classical methods. Our results indicate that solution fidelity is insensitive to the fractional index and that gradient evaluation cost scales economically with the number of time steps. As a proof of concept, we apply our algorithm to solve a range of fractional partial differential equations commonly encountered in engineering applications, such as the sub-diffusion equation, the non-linear Burgers' equation and a coupled diffusive epidemic model. We assess quantum hardware performance under realistic noise conditions, further validating the practical utility of our algorithm.

description: Can discrimination impact mothers’ mental health and parenting? Based on prior literature, I formed four hypotheses: Black mothers’ experiences with discrimination will be positively correlated to depressive and anxiety symptoms; depressive symptoms would be positively correlated with punitive and minimizing parental responses; anxiety symptoms would be positively correlated to punitive and minimizing parental responses; and, discrimination will be positively correlated to parental punitive and minimizing responses to children’s emotions. I conducted a secondary data analysis using data from the School Transitions and Academic Readiness Project (STAR) at the University of North Carolina, Greensboro (N=277). Participants (n=86) included Black mothers and their 4-6 year old children, and measures assessed discrimination, depression, anxiety, and parent emotional socialization in relation to punitive and minimizing parenting practices. Results revealed a trend association between mother-reported racial discrimination and their depressive symptoms, r = .18, p < .10, and a significant positive correlation between mother-reported discrimination and anxiety symptoms, r = .22, p < .05. There was a significant positive correlation between mothers’ depressive symptoms and parental punitive responses, r = .43, p < .05, as well as between mothers’ depressive symptoms and parental minimizing responses, r = .34, p < .05. There was a significant positive correlation between mothers’ anxiety symptoms and parental punitive responses, r = .31, p < .05, and a significant positive correlation between mothers’ anxiety symptoms and parental minimizing responses, r = .24, p < .05. There was no significant correlation between mothers’ discrimination experiences and parenting for either parental punitive or minimizing responses. Results suggest that mothers’ discrimination experiences were related to their internalizing symptoms but not the mothers’ parenting behaviors. Future longitudinal work is necessary to examine whether discrimination may impact parenting over time via parents’ depressive or anxiety symptoms.

description: Glioblastoma is the most aggressive form of brain cancer. Effective and safe treatments are urgently needed. Within the cancer cells, there is over expression of a particular protein called, P2X7R. This thesis describes P2X7R function in pre-clinical models of glioblastoma. It also describes a small molecule inhibitor of P2X7R, as a way of reducing tumour growth. The work described is hoped to lead to future clinical studies and potential novel therapeutic strategies for treatment of this devastating cancer.
