description: In this paper, we make a systematical and in-depth exploration on the phase structure and the behaviors of butterfly velocity in an Einstein-Maxwell-dilaton-axions (EMDA) model. Depending on the model parameter, there are two kinds of mechanisms driving quantum phase transition (QPT) in this model. One is the infrared (IR) geometry to be renormalization group (RG) unstable, and the other is the strength of lattice deformation leading to some kind of bifurcating solution. We also find a novel QPT in the metal phases. The study on the behavior of the butterfly velocity crossing QPT indicates that the butterfly velocity or its first derivative exhibiting local extreme depends on the QPT mechanism. Further, the scaling behaviors of the butterfly velocity in the zero-temperature limit confirm that different phases are controlled by different IR geometries. Therefore, the butterfly velocity is a good probe to QPT and it also provides a possible way to study QPT beyond holography.

description: III-nitride quantum dots (QDs) are a promising system actively studied for their ability to maintain single photon emission up to room temperature. Here, we report on the evolution of the emission properties of self-assembled GaN/AlN QDs for temperatures ranging from 5 to 300K. We carefully track the photoluminescence of a single QD and measure an optimum single photon purity of g(2)(0) = 0.05+-0.02 at 5 K and 0.17+-0.8 at 300 K. We complement this study with temperaturedependent time-resolved photoluminescence measurements (TRPL) performed on a QD ensemble to further investigate the exciton recombination dynamics of such polar zero-dimensional nanostructures. By comparing our results to past reports, we emphasize the complexity of recombination processes in this system. Instead of the more conventional mono-exponential decay typical of exciton recombination, TRPL transients display a bi-exponential feature with short- and long-lived components that persist in the low excitation regime. From the temperature insensitivity of the long-lived excitonic component, we first discard the interplay of dark-to-bright state refilling in the exciton recombination process. Besides, this temperature-invariance also highlights the absence of nonradiative exciton recombinations, a likely direct consequence of the strong carrier confinement observed in GaN/AlN QDs up to 300K. Overall, our results support the viability of these dots as a potential single-photon source for quantum applications at room temperature.

description: Abstract

The swift pace of urbanization has notably enhanced people's lifestyles, yet it has concurrently strained road infrastructure due to the surge in vehicle ownership, exacerbating traffic congestion at an alarming rate. The escalation in traffic volume stands out as a primary catalyst for road traffic accidents amid these burgeoning urban areas. In rapidly evolving metropolitan hubs, road traffic accidents loom large as a pressing concern. A significant body of research underscores the breadth of this issue and advocates for requisite remedies. Among all unnatural fatalities, road traffic accidents rank third, underscoring their gravity. Despite efforts by transportation engineers and academics to design roads adhering to appropriate standards, the inevitability of traffic accidents persists. When accidents occur, prompt identification of causative factors and implementation of apt corrective measures are imperative. This study aims to deepen understanding of the road traffic accident predicament along the Mumbai Pune Expressway (MPEW) and elucidate factors contributing to its elevated accident rates. Employing Artificial Neural Networks (ANN), this research endeavors to construct an accident prediction model to anticipate accident occurrences along the MPEW.

description: Neural Architecture Search (NAS) has recently become a topic of great interest. However, there is a potentially impactful issue within NAS that remains largely unrecognized: noise. Due to stochastic factors in neural network initialization, training, and the chosen train/validation dataset split, the performance evaluation of a neural network architecture, which is often based on a single learning run, is also stochastic. This may have a particularly large impact if a dataset is small. We therefore propose to reduce this noise by evaluating architectures based on average performance over multiple network training runs using different random seeds and cross-validation. We perform experiments for a combinatorial optimization formulation of NAS in which we vary noise reduction levels. We use the same computational budget for each noise level in terms of network training runs, i.e., we allow less architecture evaluations when averaging over more training runs. Multiple search algorithms are considered, including evolutionary algorithms which generally perform well for NAS. We use two publicly available datasets from the medical image segmentation domain where datasets are often limited and variability among samples is often high. Our results show that reducing noise in architecture evaluations enables finding better architectures by all considered search algorithms.

description: Contrastive learning has moved the state of the art for many tasks in computer vision and information retrieval in recent years. This poster is the first work that applies supervised contrastive learning to the task of product matching in e-commerce using product offers from different e-shops. More specifically, we employ a supervised contrastive learning technique to pre-train a Transformer encoder which is afterward fine-tuned for the matching task using pair-wise training data. We further propose a source-aware sampling strategy that enables contrastive learning to be applied for use cases in which the training data does not contain product identifiers. We show that applying supervised contrastive pre-training in combination with source-aware sampling significantly improves the state-of-the-art performance on several widely used benchmarks: For Abt-Buy, we reach an F1-score of 94.29 (+3.24 compared to the previous state-of-the-art), for Amazon-Google 79.28 (+ 3.7). For WDC Computers datasets, we reach improvements between +0.8 and +8.84 in F1-score depending on the training set size. Further experiments with data augmentation and self-supervised contrastive pre-training show that the former can be helpful for smaller training sets while the latter leads to a significant decline in performance due to inherent label noise. We thus conclude that contrastive pre-training has a high potential for product matching use cases in which explicit supervision is available.
`Cul-de-sac` microstrip resonators for high-speed integrated optical commutator switches.

Publisher: name: Society of Photo-Optical Instrumentation Engineers (SPIE)
Year: 2011

description: A novel microstrip resonator structure for use with integrated Y-branch optical modulators fabricated in Ti:LiNbO3 is proposed. The legs of the structure are intended to act as the electrodes of the modulator, with light being directed into each of the output waveguides of the Y-branch on alternate half-cycles of the standing wave excited in the resonator; forming an optical commutator switch. Such resonators having Al2O3 substrates were designed, fabricated, and tested. Measurements on one such resonator, operating at 7.12 GHz and having an unloaded quality factor of 123, indicating that 50 V should develop across the ends of its legs for 35 mW dissipated power; the corresponding values, from the model used to design the resonator, were 179, 50 V,and 24 mW, respectively. Using the model it is shown that a similar resonator fabricated on LiNbO3 should be able to develop about 50 V for 100 mW dissipated power at 15 GHz.

description: Coplanar slow-wave electrode structures capable of matching the velocities of microwaves to those of optical waves in compound semiconductor based electro-optic modulators are described. In such an electrode microwaves are slowed by periodically adding pairs of capacitive loading fins to the electrode to increase its capacitance per unit length, without obtaining a corresponding decrease in its inductance per unit length. Electro-optic modulators having wide bandwidths and requiring small amounts of modulating power may be realized by using slow-wave electrodes to achieve the velocity-match condition. The theory of operation of, and the results of some measurements on, electrodes of this type are presented. Copyright 1993 Society of Photo-Optical Instrumentation Engineers.

description: Influenced by deep penetration of the new generation of information technology, power systems have gradually evolved into highly coupled cyber-physical systems (CPS). Among many possible power CPS network attacks, a false data injection attacks (FDIAs) is the most serious. Taking account of the fact that the existing knowledge-driven detection process for FDIAs has been in a passive detection state for a long time and ignores the advantages of data-driven active capture of features, an active and passive hybrid detection method for power CPS FDIAs with improved adaptive Kalman filter (AKF) and convolutional neural networks (CNN) is proposed in this paper. First, we analyze the shortcomings of the traditional AKF algorithm in terms of filtering divergence and calculation speed. The state estimation algorithm based on non-negative positive-definite adaptive Kalman filter (NDAKF) is improved, and a passive detection method of FDIAs is constructed, with similarity Euclidean distance detection and residual detection at its core. Then, combined with the advantages of gate recurrent unit (GRU) and CNN in terms of temporal memory and feature-expression ability, an active detection method of FDIAs based on a GRU-CNN hybrid neural network is proposed. Finally, the results of joint knowledge-driven and data-driven parallel detection are used to define a mixed fixed-calculation formula, and an active and passive hybrid detection method of FDIAs is established, considering the characteristic constraints of the parallel mode. A simulation system example of power CPS FDIAs verifies the effectiveness and accuracy of the method proposed in this paper.

Molecular origin of driving-dependent friction in fluids

Year: 2022
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: The friction coefficient of fluids may become a function of the velocity at increased external driving. This non-Newtonian behavior is of general theoretical interest as well as of great practical importance, e.g., for the design of lubricants. While the effect has been observed in large-scale atomistic simulations of bulk liquids, its theoretical formulation and microscopic origin is not well understood. Here we use dissipation-corrected targeted molecular dynamics, which pulls apart two tagged liquid molecules in the presence of surrounding molecules and analyzes this nonequilibrium process via a generalized Langevin equation. The approach is based on a second-order cumulant expansion of Jarzynski's identity, which is shown to be valid for fluids and therefore allows for an exact computation of the friction profile as well of the underlying memory kernel. We show that velocity-dependent friction in fluids results from an intricate interplay of near-order structural effects and the non-Markovian behavior of the friction memory kernel. For complex fluids such as the model lubricant \alkane, the memory kernel exhibits a stretched-exponential long-time decay, which reflects the multitude of timescales of the system.

The quasi-fission phenomeonon of double charm $T_{cc}^+$ induced by nucleon

description: In this work, we study the reaction of a nucleon and a doubly charmed state $T_{cc}$. Under the assumption of the $T_{cc}$ as a molecular state of $D^{*}D$, the reaction of the nucleon and $T_{cc}$ is mediated by exchanges of $π$, $η$, $ρ$, and $ω$ meson, which results in split of $T_{cc}$ state with two $D$ mesons in final state. With the help of the effective Lagrangians, the cross section of $p+T^+_{cc}\to p+D^++D^0$ process is calculated, and a very large cross section can be obtained with very small incoming momentum of proton. It decrease rapidly with the increase of the momentum to about 10 mb at momenta of order of GeV. Such large cross section suggests that induced by a proton the $T_{cc}^+$ state is very easy to decay and transit to two $D$ mesons. In the rest frame of the $T_{cc}^+$ state, an obvious accumulation of final $D$ meson at small momentum region can be observed in predicted Dalitz plot, which is due to the molecular state interpretation of $T_{cc}$ state. This novel quasi-fission phenomenon of double charm molecular $T_{cc}^+$ state induced by a proton can be accessible at the forthcoming PANDA experiment.

description: A blockchain is a distributed, public or private digital ledger that uses cryptography to record transactions across computer networks to prevent records from being altered retrospectively. This paper illustrates the impact of blockchain technology on total cost, time, and risk in international commodity trading using a hypothetical case of soybean trade from Jamestown, North Dakota, to China. The results suggest that the savings include 2.3 cents per bushel of soybeans and a 41 percent reduction in the total time, including documentation and transit time. Further, the 5 percent value-at-risk model shows a reduction of 2.6 cents per bushel of soybeans traded using blockchain technology. These results are significant for agribusinesses and other agricultural stakeholders who are evaluating the benefit of adopting blockchain technology in international commodity trading.

description: Aim: The purpose of this research is consideration of attitude and motives relative to sport activities during leisure times in male and female students of Guilan University. Material and methods of research: a sample of 200 male and female students of Guilan University that had physical education 1 and 2 in 2011 and spent two sport activities in three times, they were selected as a sample by using classified sampling and answered to LAQ and LMQ questionnaire. For determining validity (specialist views) and reliability (Cronbach's Alpha=0.93, и 0.92 respectively) and SPSS (version 19) were used. For analyzing was used Kolmogorov-Smirnov test for normality of data, Pearson Correlation Coefficient, t-test, repeated measurement test and Spearman test. Results: The analysis of this research findings indicated that the most important motivation factors for participating students in sport activity in leisure times is mastery/competitive motives, avoidance/ stimulation motives, social motives, cognitive motives. In students, cognitive attitude has had more importance than emotional attitude, however; it wasn't a significant difference in the measure of its use and between two groups of male and female wasn't an observed difference in priority of motivators and their attitude. There was a positive significant relationship between attitude to support activities in students with features such as age, educational term, the number of exercise days. Also, there wasn't a significant relationship among motivation to sporting activities in individuals with features such as age, educational term, the number of exercise days. Conclusions: Therefore more attentions should be paid to the increasing motivation and attitude through institutionalizing and boosting general awareness of physical fitness.

description: A new optical commutator switch, capable of very high speed pulse generation and pulse multiplexing/demultiplexing, is proposed. It consists of an integrated optical Y-branch modulator and a `cul-de-sac' microstrip resonator. A possible compound digital optical modulator, using these optical commutators, is described. The results of measurements made on a cul-de-sac resonator, fabricated on an alumina substrate, and on optical Y-branch modulators, fabricated on z-cut lithium niobate substrates, are presented. For the resonator the unloaded quality factor was measured. For the optical Y-branch modulators the on/off ratios and percent guided powers were measured as functions of the applied voltage for several branch angles. The results indicate that optical commutators, of the type proposed, could be made. Copyright 1993 Society of Photo-Optical Instrumentation Engineers.

description: We present a chiral model describing decays of the Roper-like $Λ_c(2765)$ and $Ξ_c(2970)$ as well as those of the heavy quark spin-doublet $\{Σ_c(2455),Σ_c(2520)\}$ and $\{Ξ_c',Ξ_c(2645)\}$, by focusing on chiral representations of diquarks inside the heavy baryons. Based on our chiral model together with the heavy quark spin symmetry, we derive a relation satisfied by axial charges of the heavy baryons that controls magnitude of their one pion (kaon) decays. Besides, it is shown that the large decay widths of the Roper-like $Λ_c(2765)$ and $Ξ_c(2970)$, which cannot be implemented by conventional non-relativistic quark models, are explained by reasonable values of the axial charges. In addition, we apply the chiral model to bottom baryons and predict decay widths of the undiscovered Roper-like $Ξ_b$. We expect that our present investigation leads to elucidation of dynamical properties of the excited heavy baryons from the viewpoint of chiral symmetry.

In the first step, subjects conducted the dribble test as pre-test after 8 hours sleep a night. 10 days later, to ensure the validity of tests and test results on the learning effect, subjects did the same test again after 8 hours sleep a night. In the third stage, 36 hours of sleep deprivation as an independent variable imposed on the subjects and then the test was repeated and experimental test results were compared as recorded using paired t-test. The findings showed that 36 hour sleep deprivation decreases dribble implementation skills (p <0.001). Therefore, the findings showed that sleep deprivation can be a devastating effect on dribbling skill.

description: It is considered the directions of the development an effective methods of usage moving elements of sports and games in exercises. The experiment involved students of special medical groups that have various abnormalities of the cardiovascular system. The study was conducted in four stages: a search, the first experimental, the second experimental, final. We used questioning and education registry books of academic work. Found that the use of sports and outdoor games is students' interest, and increasing motivation for physical activity. Justified by the possibility of using games and exercises performed their adaptation by changing the pulse value. The resulting modification of gaming exercises are divided into three groups: the game in the area of heart rate to 110, 110-130 and 130-150 beats per minute. The first version of the experimental procedure at a heart rate of 110 and 110-130 beats per minute was ineffective for the emergence of significant positive changes in the functional state of the cardiovascular system students. Recommended experimental procedure based on the alternation and equivalence ratio of mobile elements and sports games and increases the heart rate to 130-150 beats per minute. Application of the method increases the overall level of physical health, improves the functional state of the cardiovascular system, health, activity and mood of the students.

description: Considered the direction of teacher’s training based on the model of a competent graduate. It is formed the criteria of the faculty of the institute of physical education and sports and the possibility of their selection. It is noted that a teacher must possess modern technologies of general and vocational education, a set of effective methods and techniques sufficient professional knowledge to provide education of future professionals (teaching, planning and management of the didactic and educational systems). It is recommended the formation of the teaching staff to consider the following: to conduct a competitive selection of teachers with experience teaching physical education and sports, coaching and tourism. Teachers also need training from the best graduates of the institute of physical education and sport.

description: You've heard of GDPR, but are you aware of how recent legislation by Congress and California may affect your beat? This session will bring together two experts in government data management to discuss the impacts of recent legislation, including: the Foundations for Evidence-based Policymaking Act, the Geospatial Data Act, the Grant Reporting Efficiency and Agreements Transparency Act, and the California Consumer Privacy Law. They will discuss how this legislation affects access to data, tracking down data, formats of data, and other nuances of the governmental data making process. They may also speculate wildly on how future legislation could impact government data management. Rebecca Williams on Twitter:@internetrebecca. Hunter Owens on Twitter:@hunter_owens

description: Obtaining a closed-form expression for the colored HOMFLY-PT polynomials of knots from $3$-strand braids carrying arbitrary $SU(N)$ representation is a challenging problem. In this paper, we confine our interest to twisted generalized hybrid weaving knots which we denote hereafter by $\hat{Q}_3(m_1,-m_2,n,\ell)$. This family of knots not only generalizes the well-known class of weaving knots but also contains an infinite family of quasi-alternating knots. Interestingly, we obtain a closed-form expression for the HOMFLY-PT polynomial of $\hat{Q}_3(m_1,-m_2,n,\ell)$ using a modified version of the Reshitikhin-Turaev method. In addition, we compute the exact coefficients of the Jones polynomials and the Alexander polynomials of quasi-alternating knots $\hat{Q}_3(1,-1,n,\pm 1)$. For these homologically-thin knots, such coefficients are known to be the ranks of their Khovanov and link Floer homologies, respectively. We also show that the asymptotic behaviour of the coefficients of the Alexander polynomial is trapezoidal. On the other hand, we compute the $[r]$-colored HOMFLY-PT polynomials of quasi alternating knots for small values of $r$. Remarkably, the study of the determinants of certain twisted weaving knots leads to establish a connection with enumerative geometry related to $m^{th}$ Lucas numbers, denoted hereafter as $L_{m,2n}$. At the end, we verify that the reformulated invariants satisfy Ooguri-Vafa conjecture and we express certain BPS integers in terms of hyper-geometric functions ${}_2 {\bf F}_1\left[a,b, c;z\right]$.

Recursive Symmetry Generation and Angular Collapse from the Square Root of i   : A Foundational Analysis
Creators: name: Thavarajah, Rogan
Publisher: name: Zenodo
Year: 2025

description: This work presents a rigorous, constructive analysis of the square root of the imaginary unit, i=eiπ/4\sqrt{i} = e^{i\pi/4}i=eiπ/4, as the minimal recursive generator of complex phase symmetry on the unit circle. Through a three-part formal structure, we demonstrate that i\sqrt{i}i is not merely an algebraic curiosity but the foundational operator from which the full cyclic group of 8th roots of unity C8⊂S1C_8 \subset S^1C8⊂S1 emerges via pure iteration.

Part 1 proves that i\sqrt{i}i is the smallest nontrivial unit complex number whose powers generate a closed cyclic orbit, and that it defines the minimal angular increment compatible with recursive closure on the unit circle.

Part 2 extends this structure to nested root operations, proving that recursive root compositions are non-commutative and asymptotically form a contractive, aperiodic angular spiral. We classify this behavior as a unique limit structure within classical complex analysis.

Part 3 3 formalizes the recursive emergence of group structure from a single transformation. It establishes that all elements of C8C_8C8 arise from first-order iteration alone, illustrating how algebraic symmetry can emerge without predefined sets.

The framework avoids introducing any new  algebraic extensions, and operates entirely within the language of complex multiplication, roots of unity, and recursive dynamics. This work lays a foundation for generalizing recursive group generation and symbolic orbit structures in future studies.

description: Key Policy Recommendations -Rural wages are increasing due to non-farm job growth, food prices remain high, and complementary technologies are being used that should support a growing demand for mechanization, though it is currently limited. -Investments in R&D can support farm intensification and improve demand for mechanization as will research on implements and machinery best suited for local use. -Reducing transaction costs can make machines more readily available, but there are still market inefficiencies that should be addressed through targeted investments beyond subsidies. -Supporting better business models that improve the efficiency of tractor hire services can help address farmer demand while stimulating private sector investment in the sector to address access in underserved areas.
