Characterization of partially coherent ultrashort XUV pulses

Modern ultrafast metrology relies on the postulate that the pulse to be measured is fully coherent, i.e. that it can be completely described by its spectrum and spectral phase. However, synthesizing fully coherent pulses is not always possible in practice, especially in the domain of emerging ultrashort X-ray sources where temporal metrology is strongly needed. As an example, the lack of longitudinal coherence, that is shot-to-shot fluctuations, of Free-Electron Lasers (FEL) has prevented so far their full amplitude and phase temporal characterization. To sort out this issue, we have adapted Frequency-Resolved Optical Gating (FROG), the first and one of the most widespread techniques for pulse characterization, to enable the measurement of partially coherent XUV pulses even down to the attosecond timescale. Especially, this technique allows one to overcome the sources of decoherence that normally prevent a pulse measurement, such as the spectrometer resolution or the presence of XUV/laser arrival time jitter.
How Is The Readiness To Carry Out Online Registration In The Malang Primary Health Care?

Background: RME is one of the information subsystems connected to other information subsystems in the health service facility, such as patient registration activities. The purpose of this study is to evaluate the readiness of PHC in Malang to use online registration applications. Methods: Quantitative descriptive research was used. The research was conducted in 15 PHCs in Malang in June 2021. The population in this study were all patients, all heads of PHCs, and all Medical Record Officers (MRO) at PHCs. The respondents were 15 physicians, 27 MRO, and 330 patients from 15 PHCs seeking medication. The data was measured using a questionnaire designed for patient groups and healthcare provider groups in PHCs per the available literature. Additionally, the scalability and repeatability coefficients for the survey questions are employed in the validity test. The response to questions was presented as an average value. Results: In accordance with the average Likert Scale, the Head of PHC (4,2), MRO (4,15), and patients (4,18) were all ready to use online registration. The study's findings about PHC revealed that 100% of PHC in Malang had adequate human resources, an effective operating system and application, a supporting computer, and a budget. Only around 50% of PHCs have an online registration policy, though. Conclusion: All PHCs and patients were ready to use online registration. According to this study, all PHCs should be ready to prepare facilities and infrastructure and implement online registration.
Threshold resummation of the rapidity distribution for Higgs production at NNLO+NNLL

We present a formalism that resums threshold-enhanced logarithms to all orders in perturbative QCD for the rapidity distribution of any colorless particle produced in hadron colliders. We achieve this by exploiting the factorization properties and K+G equations satisfied by the soft and virtual parts of the cross section. We compute for the first time compact and most general expressions in two-dimensional Mellin space for the resummed coefficients. Using various state-of-the-art multiloop and multileg results, we demonstrate the numerical impact of our resummed results up to next-to-next-to-leading order for the rapidity distribution of the Higgs boson at the LHC. We find that inclusion of these threshold logs through resummation improves the reliability of perturbative predictions.

Semi-classical bound on Lyapunov exponent and acoustic Hawking radiation in $c=1$ matrix model

A classical particle motion in an inverse harmonic potential shows the exponential sensitivity of the initial condition, and the Lyapunov exponent $\lambda_L$ is uniquely fixed by the shape of the potential. Hence, if we naively apply the bound on the Lyapunov exponent $\lambda_L \le 2\pi T/ \hbar$, it predicts the existence of the bound on temperature (the lowest temperature) in this system. We consider $N$ non-relativistic free fermions in the inverse harmonic potential ($c=1$ matrix model), and show that thermal radiation with the lowest temperature is induced quantum mechanically similar to the Hawking radiation. This radiation is related to the instability of the fermi sea through the tunneling in the bosonic non-critical string theory, and it is also related to acoustic Hawking radiation by regarding the $N$ fermions as a fermi fluid. Thus the inverse harmonic potential may be regarded as a thermal bath with the lowest temperature and the temperature bound may be saturated.
Dimensões de competitividade na era das plataformas digitais

Study objective: While there is a consolidated view of the competitive dispositions under which traditional approaches to competitive advantage operate, there is no cohesive view of how this logic manifests itself in a scenario based on technology and digitization where digital platforms operate. Therefore, this study aimed to analyze what are the prevailing competitive dispositions in digital platforms.Methodology/Approach: this is an exploratory study, correlating the topics of digital platforms and competitive advantage through a literature review on the Web of Science database, presenting a sociometric analysis of the data and a synthesis of the main competitive dispositions in digital platforms.Originality/Relevance: despite the acknowledged inadequacy of traditional strategies to explain competitiveness in the context of digital platforms, the studies dedicated to discussing this issue are still limited, and the present study has contributed by extending the discussion and providing perspectives to this novel scenario. Main results: The results define certain differences between the competitive dispositions regarding traditional enterprises and platform-based business models. Among the new elements identified, the distinct focus of the value creation process, the centrality of a networked structure as well as the use of data, and interaction of a more heterogeneous set of participants are highlighted.Theoretical/methodological contributions: the present study contributes to the current debate by indicating a first effort to align and consolidate the competitive dimensions that present themselves in digital platforms, in comparison to what is known concerning traditional pipeline approaches. Moreover, by proposing a research agenda, the development of future studies is also assisted.
Conformal Field Theory, Vertex Operator Algebra and Stochastic Loewner Evolution in Ising Model

We review the algebraic and analytic aspects of the conformal field theory (CFT) and its relation to the stochastic Loewner evolution (SLE) in an example of the Ising model. We obtain the scaling limit of the correlation functions of Ising free fermions on an arbitrary simply connected two-dimensional domain $D$. Then, we study the analytic and algebraic aspects of the fermionic CFT on $D$, using the Fock space formalism of fields, and the Clifford vertex operator algebra (VOA). These constructions lead to the conformal field theory of the Fock space fields and the fermionic Fock space of states and their relations in case of the Ising free fermions. Furthermore, we investigate the conformal structure of the fermionic Fock space fields and the Clifford VOA, namely the operator product expansions, correlation functions and differential equations. Finally, by using the Clifford VOA and the fermionic CFT, we investigate a rigorous realization of the CFT/SLE correspondence in the Ising model. First, by studying the relation between the operator formalism in the Clifford VOA and the SLE martingale generators, we find an explicit Fock space for the SLE martingale generators. Second, we obtain a subset of the SLE martingale observables in terms of the correlation functions of fermionic Fock space fields which are constructed from the Clifford VOA.
Analytical models for galactic nuclei

I present a general family of dynamical models with simple analytical potential-density pairs suited to model galactic bulges and nuclei with double power-law radial density profiles and an optional central black hole. Analytical expressions for the potential and velocity dispersion of these models are given in the spherical case. Many previously known analytical spherical models, including also the recent $\gamma / \eta$-models by Dehnen (1993) and Tremaine et al. (1994), are special cases of this family. This family also forms a complete set for constructing general galaxy models or solving Poisson's equation in the non-spherical case. In particular, a generalized Clutton-Brock (1973) and Hernquist-Ostriker (1992) orthogonal basis set is given.

Rotor-phonon coupling in perovskite CH3NH3PbI3: the origin of exceptional transport properties

Atomic dynamics takes a fundamental part in numbers of physical properties of solids like high-Tc superconductivity, semiconducting transports, and thermoelectricity. Perovskite CH3NH3PbI3 exhibits outstanding photovoltaic performances, but the exact physical scenario has not been established yet, due to the inadequate understanding of the atomic dynamics and exceptional transport properties. We present a complete atomic dynamic picture consisting of phonons, rotational modes of protons and molecular vibrational modes, which is constructed by carrying out high-resolution time-of-flight inelastic neutron scattering measurements in a wide energy window ranging from 0.0036 to 54 meV on a large single crystal sample. A three-fold rotational mode of protons activated around 80 K reduces the lifetimes of acoustic and optical phonons down to about 4.5 ps and below 1 ps at 150 K, respectively. The orthorhombic to tetragonal phase transition takes place with a slower four-fold rotational mode of the C-N axis concomitantly setting in at ~ 165 K, above which the optical phonons are too broadened to be distinguished whereas the acoustic ones are still robust. The significantly reduced lifetimes of optical phonons are linked to the smaller mobility of charge carriers while the ultralow lattice thermal conductivity is attributed to nanoscale mean free paths of acoustic phonons. These microscopic insights provide a solid standing point, on which perovskite solar cells can be understood more accurately and their performances are perhaps further optimized. The revealed rotor-phonon coupling opens up an emergent opportunity to create unprecedented functionalities of materials.
Friction and Heat Transfer in Membrane Distillation Channels: An Experimental Study on Conventional and Novel Spacers

The results of an experimental investigation on pressure drop and heat transfer in spacer-filled plane channels, which are representative of Membrane Distillation units, are presented and discussed. Local and mean heat transfer coefficients were obtained by using Thermochromic Liquid Crystals and Digital Image Processing. The performances of a novel spacer geometry, consisting of spheres that are connected by cylindrical rods, and are hereafter named spheres spacers, were compared with those of more conventional woven and overlapped spacers at equal values of the Reynolds number Re (in the range ~150 to ~2500), the pitch-to-channel height ratio, the flow attack angle and the thermal boundary conditions (two-side heat transfer). For any flow rate, the novel spacer geometry provided the least friction coefficient and a mean Nusselt number intermediate between those of the overlapped and the woven spacers. For any pressure drop and for any pumping power, the novel spacer provided the highest mean Nusselt number over the whole Reynolds number range that was investigated. The influence of buoyancy was also assessed for the case of the horizontal channels. Under the experimental conditions (channel height H ≈ 1 cm, ΔT ≈ 10 °C), it was found to be large in empty (spacer-less) channels that were up to Re ≈ 1200 (corresponding to a Richardson number Ri of ~0.1), but it was much smaller and limited to the range Re < ~500 (Ri < ~0.5) in the spacer-filled channels.
Semiclassical theory of cavity-assisted atom cooling

We present a systematic semiclassical model for the simulation of the dynamics of a single two-level atom strongly coupled to a driven high-finesse optical cavity. From the Fokker-Planck equation of the combined atom-field Wigner function we derive stochastic differential equations for the atomic motion and the cavity field. The corresponding noise sources exhibit strong correlations between the atomic momentum fluctuations and the noise in the phase quadrature of the cavity field. The model provides an effective tool to investigate localization effects as well as cooling and trapping times. In addition, we can continuously study the transition from a few-photon quantum field to the classical limit of a large coherent field amplitude.
Comparative Pathogenomic Analysis of Two Banana Pathogenic Dickeya Strains Isolated from China and the Philippines

Dickeya is a major and typical member of soft rot Pectobacteriaceae (SRP) with a wide range of plant hosts worldwide. Previous studies have identified D. zeae as the causal agent of banana soft rot disease in China. In 2017, we obtained banana soft rot pathogen strain FZ06 from the Philippines. Genome sequencing and analysis indicated that FZ06 can be classified as D. dadantii and represents a novel subspecies of D. dadantii, which we propose to name as subsp. paradisiaca. Compared with Chinese banana soft rot pathogenic strain D. zeae MS2, strain FZ06 has a similar host range but different virulence; FZ06 is significantly less virulent to banana and potato but more virulent to Chinese cabbage and onion. Characterization of virulence factors revealed obviously less production of pectate lyases (Pels), polygalacturonases (Pehs), proteases (Prts), and extrapolysaccharides (EPSs), as well as lower swimming and swarming motility and biofilm formation in strain FZ06. Genomic comparison of the two strains revealed five extra gene clusters in FZ06, including one Stt-type T2SS, three T4SSs, and one T4P. Expression of cell wall degrading enzyme (CWDE)-encoding genes is significantly lower in FZ06 than in MS2.
Relations between physical observables: what is better?

We investigate some possible relations between physical observables and estimate the "cosmic variance" which affects these measurements. We focus on redshift and angular-distance and we discuss the difference in considering the redshift as function of the angular-distance rather than the usually considered inverse relation. Already at linear level in metric perturbations, we find a significant difference. Indeed, even if both relations are led by source radial velocity for close enough sources, this effect is suppressed by 2 orders of magnitude in the redshift/angular-distance relation. This fact can significantly reduce the theoretical uncertainty for close sources already investigated in the literature for the angular-distance/redshift relation and open a new scenario for clarifying the tension in the measurement of $H_0$ from local sources rather than from the CMB.
Decentralized adaptive control applied to two links of a five degrees of freedom robot, using the polynomial technique

The objective of this work is to design and implement decentralized adaptive controllers in order to perform the position control of two links of an electromechanical manipulator robot with five degrees of freedom (DOF 5). The manipulator robot is consisted of five rotational joints, four links and a claw. Five DC motors are used to drive the robot and the motion transmission from the motors to the joints is achieved by gear trains. Models of the manipulators robots are obtained using Newton-Euler or Lagrange equations; and are coupled and nonlinear. In this work, the model of the links of the manipulator robot is obtained in real time for each sampling period. The parameters of the links to be controlled are identified by recursive least squares (RLS) method, according to data from the links, and are used in the designs of adaptive controllers for the positions control of the joints of the links under analysis. In the end, the experimental results are presented, like the evaluation of the performance achieved by the manipulator robot links.
Oligometastatic Disease: When Stage IV Breast Cancer Could Be “Cured”

Simple Summary Breast cancers diagnosed at an advanced stage are often incurable, and systemic strategies such as chemotherapy, hormonotherapy, immunotherapy, and/or targeted therapy are the basis of treatment. Imaging tests are always required to determine the extent of the disease, and in selected cases with few metastatic lesions and organs involved (oligometastatic disease), radical treatment with surgery or radiotherapy may be considered to improve prognosis. In that situation, although it is basically impossible to know whether it is a curable disease or not, more and more patients achieve the status of no long-term evidence of disease. More prospective studies are needed to assess which patients may benefit. Abstract Although metastatic breast cancer remains an incurable disease, there are patients with a limited number of metastatic lesions that, in addition to systemic therapy, can be treated with “radical therapy” and sometimes reach the status of no long-term evidence of disease. Whether or not these patients can be considered cured is still a matter of debate. Unfortunately, the definition of the oligometastatic disease remains unclear, and it can occur with multiple different presentations. The absence of remarkable biomarkers, the difficulty in designing the appropriate clinical trials, and the failure to offer this group of patients radical approaches in advanced-stage clinical trials are just some of the current problems that we face in treating patients with oligometastatic breast cancer. Although most of the data come from retrospective studies and do not use the same definition of “oligometastatic disease,” here we review the main studies exploring the role of surgery or radiotherapy in patients with the oligometastatic disease and the different results. Some, but not all, studies have shown an increase in survival when surgery and/or radiotherapy were performed for oligometastatic disease. However, better clinical trial designs are needed to confirm the role of “aggressive” approaches for patients with breast cancer and oligometastatic disease.
Evaluación del impacto del preprocesamiento de imágenes en la segmentación del iris

Segmentation is one of the most important stages in iris recognition systems. In this paper, image preprocessing algorithms are applied in order to evaluate their impact on successful iris segmentation. The preprocessing algorithms are based on histogram adjustment, Gaussian filters and suppression of specular reflections in human eye images. The segmentation method introduced by Masek is applied on 199 images acquired under unconstrained conditions, belonging to the CASIA-irisV3 database, before and after applying the preprocessing algorithms. Then, the impact of image preprocessing algorithms on the percentage of successful iris segmentation is evaluated by means of a visual inspection of images in order to determine if circumferences of iris and pupil were detected correctly. An increase from 59% to 73% in percentage of successful iris segmentation is obtained with an algorithm that combine elimination of specular reflections, followed by the implementation of a Gaussian filter having a 5x5 kernel. The results highlight the importance of a preprocessing stage as a previous step in order to improve the performance during the edge detection and iris segmentation processes.
Metabolic Reprogramming in Tumor-Associated Macrophages in the Ovarian Tumor Microenvironment

Simple Summary The highly metastatic and immunosuppressive microenvironment of ovarian cancers is a major determinant of the aggressive nature and therapeutic resistance of ovarian cancer. Therefore, we believe that a thorough understanding of the mechanisms that regulate the composition and function of the tumor microenvironment is critical for the development of a more effective course of treatment for this devastating malignancy. This review summarizes the recent literature on the major metabolic pathways affecting macrophage immune metabolism and its impact on phenotypic and functional changes in macrophages in the ovarian tumor microenvironment. Abstract The interaction between tumor cells and macrophages in the tumor microenvironment plays an essential role in metabolic changes in macrophages and reprograms them towards a pro-tumorigenic phenotype. Increasing evidence indicates that macrophage metabolism is a highly complex process and may not be as simple as previously thought. Pro-inflammatory stimuli switch macrophages towards an M1-like phenotype and rely mainly on aerobic glycolysis and fatty acid synthesis, whereas anti-inflammatory stimuli switch macrophages towards an M2-like phenotype. M2-like macrophages depend more on oxidative phosphorylation (OXPHOS) and fatty acid oxidation. However, this metabolically reprogrammed phenotypic switch in macrophages remained a mystery for a while. Therefore, through this review, we tend to describe how macrophage immunometabolism determines macrophage phenotypes and functions in tumor microenvironments (TMEs). Furthermore, we have discussed how metabolic reprogramming in TAM can be used for therapeutic intervention and drug resistance in ovarian cancer.
