Factoring Algebraic Error for Relative Pose Estimation

We address the problem of estimating the relative pose, i.e. translation and rotation, of two calibrated cameras from image point correspondences. Our approach is to factor the nonlinear algebraic pose error functional into translational and rotational components, and to optimize translation and rotation independently. This factorization admits subproblems that can be solved using direct methods with practical guarantees on global optimality. That is, for a given translation, the corresponding optimal rotation can directly be determined, and vice versa. We show that these subproblems are equivalent to computing the least eigenvector of second- and fourth-order symmetric tensors. When neither translation or rotation is known, alternating translation and rotation optimization leads to a simple, efficient, and robust algorithm for pose estimation that improves on the well-known 5- and 8-point methods.
Dynamics of delay-coupled spherical bubbles

The behavior of mutually coupled cavitation bubbles can change considerably when a finite speed of sound propagation in the liquid is taken into account. This holds for the radial oscillations of the bubbles as well as for the interaction (Bjerknes) forces between them. Starting from linear analysis of the equations of motion, nonlinear bubble dynamics is investigated numerically. Some results are reported for illustration of effects that may have significant impact on the modeling of cavitation structures in certain parameter regimes.
Ground-state phase diagram of the quantum J1−J2 model on the honeycomb lattice

We study the ground-state phase diagram of the quantum $J_1-J_2$ model on the honeycomb lattice by means of an entangled-plaquette variational ansatz. Values of energy and relevant order parameters are computed in the range $0\le {J_2}/{J_1} \le 1$. The system displays classical order for ${J_2}/{J_1}\lesssim 0.2$ (N\'eel), and for $J_2/J_1 \gtrsim 0.4$ (collinear). In the intermediate region, the ground-state is disordered. Our results show that the reduction of the half-filled Hubbard model to the model studied here does not yield accurate predictions.
Palynology of Bijori formation (Upper Permian) in Satpura Gondwana Basin, India

Bijori Formation, generally equated to the Raniganj Formation (Upper Permian) of Damodar Basin, contains a striated-disaecate dominant mioflora with abundantly represented Densipollenites and Corisaccites-Guttulapollenites and also some other miospores indicating a Permo-Triassic affinity. In the Lower Gondwana deposits of Indian Peninsula, Densipollenites-rich assemblages are characteristic of the coal-less facies towards the close of Raniganj Formation (Upper Permian). but in Satpura Basin comparable mioflora with some definite younger elements seems to exhibit Lower Triassic influence in the Upper Bijoris. By the discovery of this mioflora. the presence of a distinctive assemblage having a Lower Panchet affinity is indicated towards the top of Bijori Formation. There is, Obviously, a big scope for similar studies in the whole of Satpura Basin.
Evolving networks： from topology to dynamics

A multi-local-world model is introduced to describe the evolving networks that have a localization property such as the Intemet. Based on this model, we show that the traffic load defined by "betweenness centrality" on the multi-local-world scale-free networks' model also follows a power law form. In this kind of network, a few vertices have heavier loads and so play more important roles than the others in the network.
Limit theory for U-statistics under geometric and topological constraints with rare events

Abstract We study the geometric and topological features of U-statistics of order k when the k-tuples satisfying geometric and topological constraints do not occur frequently. Using appropriate scaling, we establish the convergence of U-statistics in vague topology, while the structure of a non-degenerate limit measure is also revealed. Our general result shows various limit theorems for geometric and topological statistics, including persistent Betti numbers of Čech complexes, the volume of simplices, a functional of the Morse critical points, and values of the min-type distance function. The required vague convergence can be obtained as a result of the limit theorem for point processes induced by U-statistics. The latter convergence particularly occurs in the $\mathcal M_0$ -topology.
Synthesis and Biomedical Applications of Zirconium Nanoparticles: Advanced Leaps and Bounds in the Recent Past

Many synthetic routes manufacture zirconium nanoparticles in metal oxide, nitride, and other combination forms. Coupled with other variables such as concentration, pH, and form of precursor used, the various synthetic methods support synthesizing the zirconium metal oxide nanoparticles with changed features. Various synthetic methods were studied, such as sol-gel, hydrothermal, laser ablation, and precipitation. All have different synthetic routes, different precursors and solvents were sued, and the product was characterized by SEM, TEM, photo luminance spectroscopy, UV-absorption spectroscopy, and powder X-ray diffraction. X-ray diffraction determined the crystal structure by identifying the crystal shape, arrangement of atoms, and spacing between them. SEM and TEM studied the particle size and morphology of nanoparticles. UV-visible absorption spectroscopy and PL spectroscopy were used for the determination of optical properties of nanoparticles. Zirconium oxide nanoparticles have many applications in the medical field. The review study primarily focuses on the efficient combination of zirconium dioxide with other additive materials and functionalization techniques used to improve the material's properties, assisting the use of the material in hip arthroplasty and bone tissue applications. The development of sophisticated near-infrared (NIR) absorbing small molecules for useful phototheranostic applications was discussed in this paper.
Universal redundancy rates for B-processes do not exist

Shows that for any sequence /spl rho/(n)=o(n) and any sequence of prefix codes, there is a B-process of entropy arbitrarily close to the maximum possible entropy for which the expected redundancy is at least as large as /spl rho/(n) for infinitely many n. This extends earlier work of the first author, whose examples had 0 entropy, [Shields, 1993]. The class of B-processes, that is, stationary codings of i.i. d. processes, includes the aperiodic Markov chains and functions thereof, aperiodic renewal and regenerative processes, and independent processes, as well as many other processes of interest. In particular, the results show that the search for a universal redundancy-rate for the class of all B-processes is doomed to failure, and redundancy rates for any given subclass must be obtained by direct analysis of that subclass. <<ETX>>
Dietary Patterns of Treatment–Resistant Depression Patients

Depression is a common mental disorder that occurs all over the world with treatment resistance commonly seen in clinical practice. Ketamine exhibits an antidepressant that is more often used in the case of treatment-resistant depression (TRD) in MDD and BP. Research emphasizes that a healthy diet and the nutrients it contains can lower the risk of developing depression and form a strategy that supports conventional treatment. The aim of the study was to evaluate the patients’ diet and to analyze the effect of ketamine on food intake among patients with TRD. The study involved 15 patients suffering from treatment-resistant depression and 15 healthy volunteers. The data required for the analysis were collected using the food frequency questionnaire (FFQ) and 4-day food diaries. The study group was statistically significantly less likely to consume milk and plain milk beverages, plain white cheese, wholemeal bread, various vegetables, wine, and drinks. Our results show several disorders in the eating habits of patients with treatment–resistant depression. After the administration of ketamine, the patients consumed significantly less protein, fats, monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA), fiber, tryptophan, vitamins, and minerals compared to the control group. There is a lack of research describing the effects of ketamine on nutrition. In order to confirm the results of the study, more participants are required, and the assessment of food diaries filled in at the patient’s home with a longer interval after the last dose of ketamine as well.
Using Springs as Sentinels of Climate Change in Nature Parks North and South of the Alps: A Critical Evaluation of Methodological Aspects and Recommendations for Long-Term Monitoring

Spring ecosystems are diverse transition zones between ground- and surface-water habitats. Due to their characteristics and vulnerable species assemblages, springs are considered indicator systems for monitoring environmental change. In particular, climate change is expected to alter spring-ecosystem features, such as water temperature and discharge, affecting otherwise typically stable biotic and abiotic conditions. However, reliable trend-development recognition and analysis require a uniform methodology and comparable data series over long periods of time. Spring research findings in the Berchtesgaden National Park and the Adamello-Brenta Nature Park have been consolidated to develop methodological recommendations to create lasting societal-added value. The successful transfer of the methodology to the Bavarian Forest National Park and the experienced contribution of the Bavarian Association for the Protection of Nature (Bavarian Climate Alliance) strongly improved method validations. Our resulting, newly developed recommendations for long-term spring monitoring have a focus on climate change impacts and aim at providing a decision-making basis for establishing programs in similar ecological and climatic zones. Uniform site-selection criteria and selected climate-sensitive parameters are indicated. This includes documenting the spring’s environment and structure, measuring abiotic parameters, and determining selected floristic and faunistic groups. We recommend measurement and sampling-survey intervals ranging from 3(4) times yearly to every 5 years, depending on the parameter. We further suggest a database system that integrates all monitoring parameters to ensure consistent data management and storage. Analysing the data resulting from our new holistic spring monitoring methodology should provide critical knowledge about putatively changing ecosystems that can then be used as evidence of climate-change impact on spring ecosystems.
Adaptive projected subgradient method and its applications to set theoretic adaptive filtering

This paper presents an algorithm, named adaptive projected subgradient method that can minimize asymptotically certain sequence of nonnegative convex functions over a closed convex set in a real Hubert space. The proposed algorithm is a natural extension of the Polyak's subgradient algorithm, for unsmooth convex optimization problem with a fixed target value, to the case where the convex objective itself keeps changing in the whole process. The main theorem, showing the strong convergence of the algorithm as well as the asymptotic optimality of the sequence generated by the algorithm, can serve as a unified guiding principle of a wide range of set theoretic adaptive filtering schemes for nonstationary random processes. These include not only the existing adaptive filtering techniques, e.g. NLMS, projected NLMS, constrained NLMS, APA, and adaptive parallel outer projection algorithm etc, but also new techniques, e.g., adaptive parallel min-max projection algorithm, and their embedded constraint versions. Numerical examples show that the proposed techniques are well-suited for robust adaptive signal processing problems.
Meta-analysis of organizational and supply chain dynamic capabilities: A theoretical-conceptual relationship

Creating resilient supply chains and more agile and competitive organizations are challenges that companies face today in a highly competitive and changing environment. Therefore, organizations must understand the importance of developing and strengthening their dynamic capabilities (DC) and supply chain dynamic capabilities (SCDC) in order to improve their market performance, participation, and sustainability. This study performs a meta-analysis of the literature related to organizational and supply chain dynamic capabilities, which together constitute an ecosystem of capabilities that every organization should develop to improve performance. After an exhaustive review of 1203 articles aligned with the base theoretical construct of dynamic capabilities, the information was decanted from strict filters. This allowed to evidence the contribution of this construct in literature aligned with organizational performance, as well as to identify the contribution that can be made by other constructs aligned with the dynamic capabilities’ ecosystem. The findings show a theoretical relationship between both constructs, presenting how the supply chain dynamic capabilities constitute a specialization and differentiation of organizational dynamic capabilities. In addition, the study highlights their major contribution to developing competitive advantages and improving organizational performance.
Characterizing Technology's Influence on Distractive Behavior at Signalized Intersections

: Distracted driving existed since the invention of the automo- bile; however, the emergence of the cell phone and electronic devices created another source of distraction that affected drivers visually, physically, cognitively, and audibly. Many studies investigated factors that influenced saturation flow and startup lost time at a signalized intersection, but the impact of new distractions, such as electronic devices and in-vehicle entertainment systems, remained less investigated. This study aimed to char- acterize technology’s influence on driver behavior at intersections and the impact of distractions on startup lost time through a field test conducted at three intersections in Texas. This study used observational analysis and hypothesis testing to understand distraction behaviors and their impacts on individual and aggregated startup lost time. On average, 15% of drivers experienced distraction during a red indication, and a cell phone distracted more than 60% of these drivers. However, in vehicles located behind a heavy vehicle at an intersection, 20% of drivers were distracted, and 80% used a cell phone. Statistical analysis showed that distraction caused signifi- cantly higher headways and total lost times than non-distraction conditions. More importantly, technology-induced distraction, which created significant intersection delay, was more uncertain and varied from event to event more than non-technology-induced delay. This study showed that technology-induced distractions from the prevalent use of cell phones created an impact on startup lost time and saturation flow, which remained critical to properly determine the phase and cycle lengths.
Relationship of Corporal Punishment and Student’s Behavior of Secondary School Students of Quetta City

Corporal/Physical punishment exercises in the secondary level school students have negativeassociations on the behavior patterns of the students. The corporal punishment exercises not onlyaffect the student’s social life but also badly affect their professional life, these negative impacts ontheir behavior manage to the authorities whom the students are working outside the school and createhurdles in achieving their educational goals. For this purpose descriptive type of research wasconducted. This research was correlational in nature. The population for this research study was takenall the secondary boys’ and girls’ schools of the Quetta city, Quetta District. A sample of 200 studentswas taken in order to find out the results of the study. A questionnaire was designed in order to collectdata as a tool of the research study. There is a moderate negative relationship between theCorporal/Physical punishment and student’s behavior of the secondary schools. The students whoreceived corporal punishment had a negative impact on their behavior than those who didn’t receiveany type of punishment.
Derived Representation Schemes and Noncommutative Geometry

Some 15 years ago M. Kontsevich and A. Rosenberg [KR] proposed a heuristic principle according to which the family of schemes ${Rep_n(A)}$ parametrizing the finite-dimensional represen- tations of a noncommutative algebra A should be thought of as a substitute or "approximation" for Spec(A). The idea is that every property or noncommutative geometric structure on A should induce a corresponding geometric property or structure on $Rep_n(A)$ for all n. In recent years, many interesting structures in noncommutative geometry have originated from this idea. In practice, however, if an associative algebra A possesses a property of geometric nature (e.g., A is a NC complete intersection, Cohen-Macaulay, Calabi-Yau, etc.), it often happens that, for some n, the scheme $Rep_n(A)$ fails to have the corresponding property in the usual algebro-geometric sense. The reason for this seems to be that the representation functor $Rep_n$ is not "exact" and should be replaced by its derived functor $DRep_n$ (in the sense of non-abelian homological algebra). The higher homology of $DRep_n(A)$, which we call representation homology, obstructs $Rep_n(A)$ from having the desired property and thus measures the failure of the Kontsevich-Rosenberg "approximation. " In this paper, which is mostly a survey, we prove several results confirming this intuition. We also give a number of examples and explicit computations illustrating the theory developed in [BKR] and [BR].
EFFECT OF GROWTH PHASES OF SACCHAROMYCES CERVISIAE ON THE EFFICIENCY OF EXPRESSION FOREIGN GENE(S)

The direct transfer of genetics materials into yeast cells Saccharomyces cereviciae as well as using of amylase, cellulase and Osmo gene(s) as gene(s) marker, for measuring the efficiency of transformations during the growth curve of the cells was investigated. A framework is developed for an adequate comparison of data obtained during different phases of growth. Results indicated that the exponential phase is the best phase of introduce DNA across the cell membrane. Whereas transformation percentage reached its peak at the end of exponential phase. Results also revealed that the transformation rates of cellulase expression gene(s) were lower than the transformation rates of α-amylase expression gene(s). These results might be due to the different regulatory genes with different locations which are proposed to explain the ability of producing the enzymes by the same yeast transformed isolates in a different rates. On the contrary, the high concentrations of NaCl decreased gradually the transformation percentage during the exponential period. On the other hand, no transformants can be obtained in the high concentrations of NaCl on the early exponential phase or stationary phase. This may due to a very low survival rates of cells. The greatest transformation rate which were recorded at the exponential phase (late exponential phase) in particular, may be attributed to the thickness of cell wall of yeast wall than other phases. The results concerning efficiency of transformants to express foreign genes did not only indicate possible transfer the foreign genes but are also instrument in developing a goal directed optimization strategy of the growth rate in the application of direct transformation technique.
The Little Fire Ant (Hymenoptera: Formicidae): A Global Perspective

Abstract Wasmannia auropunctata (Roger) is an invasive tramp ant species that has been transported globally since [at least] the early twentieth century. It is often claimed that despite the negative impacts associated with this species and its listing among the world's worst invasive species, very little research attention has been paid to W. auropuntata. Although the need for future research exists, there is currently a considerable body of research from around the world and spanning back to the 1920's on this species. Here we synthesize over 200 peer reviewed research manuscripts, book chapters, conference presentations, and media reports of new distributions spanning 1929–2022 culminating in a comprehensive literature review on W. auropunctata. This review covers all current knowledge on this species and is intended to serve as a quick reference for future research and provide the reference resources for those seeking more in-depth information on specific topics. Topics included in this review include taxonomic identification, current global distribution and pathways, life history, impacts, detection, and control. We discuss where consensus and ambiguity currently lie within the research community, identify contextual considerations for future researchers when interpreting data, and suggest where we believe more research or clarifications are needed.
Radial Interplanetary Mean Free Paths Inferred from Anomalous Cosmic Ray Observations in the Outer Heliosphere

We use two independent techniques to estimate the rigidity dependence of the interplanetary mean free pathlength in the outer heliosphere in 1998: I) inferences from gradients of anomalous cosmic rays (ACRs) between Voyagers 1 and 2 and 2) inferences from the shape of the ACR energy spectra. Both techniques indicate that the mean free path increases rapidly between ""0.25 GV and I GV but is independent of rigidity above "'J GV, in agreement with the dependence used by Steenberg et al. (I 999) to fit the 1998 ACR energy spectra using a full-drift, two-dimensional solution to the transport equation. The gradient method also yields an estimate of the magnitude of the mean free path, which is "'2 ± 0.4 AU at 1.5 GV, the same as the value of 2.0 AU used by Steenberg et al. (1999). In addition, we find that the mean free path at 0.42 GV is 1.4 ± 0.8 from anisotropy measurements of 4-7.8 MeV/nuc ACR He from Voyager 1. This value is consistent with the estimate from the gradient method and from the Steenberg et al. fits. At 1.5 GV, the mean free path during the 1998 solar minimum is "'I 0 times larger than that estimated for solar maximum in 1990, suggesting that for A>O, when particles drift from high to low latitudes, the radial gradient at low latitudes reflects the much smaller radial gradients theoretically expected (Zank et al. 1998) at higher latitudes.
A generalization of vector valued Jacobi forms

The Fourier–Jacobi coefficients of vector valued Siegel mod ular forms of degree n are more general functions than vector valued Jacobi forms d efined by Ziegler [9] even whenn D 2. We define generalized vector valued Jacobi forms correspo nding to the above coefficients when n D 2 and prove that such a space is isomorphic to a certain product of spaces of usual scalar valued Jacobi form s f various weights. This isomorphism is realized by certain linear holomorphic diff erential operators. The half-integral weight case is also treated.
