description: Topological optical states exhibit unique immunity to defects and the ability to propagate without losses rendering them ideal for photonic applications.A powerful class of such states is based on time-reversal symmetry breaking of the optical response.However, existing proposals either involve sophisticated and bulky structural designs or can only operate in the microwave regime. Here, we propose and provide a theoretical proof-of-principle demonstration for highly confined topologically protected optical states to be realized at infrared frequencies in a simple 2D material structure-a periodically patterned graphene monolayer-subject to a magnetic field below 1 tesla. In our graphene honeycomb superlattice structures plasmons exhibit substantial nonreciprocal behavior at the superlattice junctions, leading to the emergence of topologically protected edge states and localized bulk modes enabled by the strong magneto-optical response of this material, which leads to time-reversal-symmetry breaking already at moderate static magnetic fields. The proposed approach is simple and robust for realizing topologically nontrivial 2D optical states, not only in graphene, but also in other 2D atomic layers, and could pave the way for realizing fast, nanoscale, defect-immune devices for integrated photonics applications.

description: On the 4th and 5th of November 2021, more than 50 scholars from different disciplines and countries came together in an online conference to discuss the multiple aspects of Transformations of Infrastructure Systems at the second international conference organized by the Research Training Group KRITIS at the Technical University of Darmstadt, Germany. The focus of this conference was on the dynamic and changing nature of infrastructure systems and describing, understanding, and explaining transformation processes of infrastructures. Within the four multidisciplinary panels (Safety, Cultures, Governance, and both Temporality and Spatiality) the participants shared their research and knowledge on various aspects of transformation of infrastructure Systems. The conference gave an insight into the triggers of transformations and highlighted the conditions under which they take place and the consequences. The keynote lectures by Prof. Dr. Timothy Moss (Humboldt University of Berlin), Dr. Anique Hommels (Maastricht University), and Niklas Vespermann (Federal Network Agency, Germany) further highlighted and deepened the aspects relevant to this context.

description: To ensure viability, it is necessary for an intertwined supply network (ISN) system to optimise network structure to provide flexible redundancy in response to changing environment. Considering resilience methods are usually designed as reactions to single discrete disruptions rather than situational reactions to real-time changes, this study proposes a novel redundancy optimisation approach dynamically providing each demand market with a pair of supply routes to optimise the flexible redundancy of ISN, thereby ensuring the survivability of supply chains and demand markets under continuous changes. Based on this, we propose the ISN design (ISND) model to capture the trade-off between total cost and viability performance under facility and transportation disruption. The Lagrangian relaxation algorithm, combined with the sub-gradient method and the improved cellular genetic algorithm, are utilised for solving problems of different scales. To test the performance of the model and corresponding algorithms, we also conduct a numerical analysis of the data from medical equipment ISN in southern China. The results indicate that the ISND model can effectively optimise ISN structures, which makes it possible to dynamically provide flexible redundancy; the two algorithms also show good calculation efficiency. The relationship between ISN structure and viability performance is thus observed and explained.

description: In the so-called (2,2) theory, which is the U(N)^4 circular quiver superconformal Chern-Simons theory with levels (k,0,-k,0), it was known that the instanton effects are described by the free energy of topological strings whose Gopakumar-Vafa invariants coincide with those of the local D_5 del Pezzo geometry. By considering two types of one-parameter rank deformations U(N) x U(N+M) x U(N+2M) x U(N+M) and U(N+M) x U(N) x U(N+M) x U(N), we classify the known diagonal BPS indices by degrees. Together with other two types of one-parameter deformations, we further propose the topological string expression when both of the above two deformations are turned on.

description: Kagome materials are emerging platforms for studying charge and spin orders. In this work, we have revealed a rich lattice instability in a $\mathbb{Z}_2$ kagome metal ScV$_6$Sn$_6$ by first-principles calculations. Beyond verifying the $\sqrt3 \times \sqrt3 \times 3$ charge density wave (CDW) order observed by the recent experiment, we further identified three more possible CDW structures, i.e., $\sqrt3 \times \sqrt3 \times 2$ CDW with $P6/mmm$ symmetry, $2 \times 2 \times 2$ CDW with $Immm$ symmetry, and $2 \times 2 \times 2$ CDW with $P6/mmm$ symmetry. The former two are more energetically favored than the $\sqrt3 \times \sqrt3 \times 3$ phase, while the third one is comparable in energy. These CDW distortions involve mainly out-of-plane motions of Sc and Sn atoms, while V atoms constituting the kagome net are almost unchanged. We attribute the lattice instability to the smallness of Sc atomic radius. In contrast, such an instability disappears in its sister compounds $R$V$_6$Sn$_6$ ($R$ is Y, or a rare-earth element) because $R$ has a larger radius. Our work indicates that ScV$_6$Sn$_6$ might exhibit varied CDW phases in different experimental conditions and provides insights to explore rich charge orders in kagome materials.

description: To discuss the properties of metamaterials on physical grounds and to consider them in applications, effective material parameters are usually introduced and assigned to a given metamaterial. In most cases, only weak spatial dispersion is considered. It allows to assign local material properties, i.e. a permittivity and a permeability. However, this turned out to be insufficient. To solve this problem, we study here the effective properties of metamaterials with constitutive relations beyond a local response and take strong spatial dispersion into account. The isofrequency surfaces of the dispersion relation are investigated and compared to those of an actual metamaterial. The significant improvement provides evidence for the necessity to use nonlocal material laws in the effective description of metamaterials. The general formulation we choose here renders our approach applicable to a wide class of metamaterials.

description: We consider mod p Hilbert modular forms associated to a totally real field of degree d in which p is unramified. We prove that every such form arises by multiplication by partial Hasse invariants from one whose weight (a d-tuple of integers) lies in a certain cone contained in the set of non-negative weights, answering a question of Andreatta and Goren. The proof is based on properties of the Goren-Oort stratification on mod p Hilbert modular varieties established by Goren and Oort, and Tian and Xiao.

description: We consider the large $L$ limit of one dimensional Schrödinger operators $H_L=-d^2/dx^2 + V_1(x) + V_{2,L}(x)$ in two cases: when $V_{2,L}(x)=V_2(x-L)$ and when $V_{2,L}(x)=e^{-cL}δ(x-L)$. This is motivated by some recent work of Herbst and Mavi where $V_{2,L}$ is replaced by a Dirichlet boundary condition at $L$. The Hamiltonian $H_L$ converges to $H = -d^2/dx^2 + V_1(x)$ as $L\to \infty$ in the strong resolvent sense (and even in the norm resolvent sense for our second case). However, most of the resonances of $H_L$ do not converge to those of $H$. Instead, they crowd together and converge onto a horizontal line: the real axis in our first case and the line $\Im(k)=-c/2$ in our second case. In the region below the horizontal line resonances of $H_L$ converge to the reflectionless points of $H$ and to those of $-d^2/dx^2 + V_2(x)$. It is only in the region between the real axis and the horizontal line (empty in our first case) that resonances of $H_L$ converge to resonances of $H$. Although the resonances of $H$ may not be close to any resonance of $H_L$ we show that they still influence the time evolution under $H_L$ for a long time when $L$ is large.

description: The demand for plastic products is on the rise with increasing demand in different sectors of human society. This amounts to the generation of plastic waste globally at an alarming rate thereby leading to plastic pollution. This study identified that plastic pollution is one of the challenges plaguing the universe status quo with more than estimated eighty million tons of plastic-related wastes being released into the sea annually. Plastic pollution affects the health, socio-economic and agricultural sectors in Nigeria in a profound way. This study further identified the great need for proper plastic waste management strategies in order to enhance public health in Nigeria. It recommended the innovative tools of poetry, music and educational blogs among others for use in plastic pollution education for sustainable development in Nigeria. This study issued a clarion call for more intensive research on the innovative use of poetry for awareness creation on plastic waste management in Nigeria. It concluded by highlighting the need for greater international collaborations and partnerships in finding a sustainable solution to the global menace

description: Effective integration of terrestrial and non-terrestrial segments is one of the key research avenues in the design of current and future wireless communication networks. To this aim, modern communication-satellite constellations intend to attain sufficiently high throughput in terms of bit rate per unit area on the ground by rather aggressive patterns of spatial frequency reuse. This goal calls for on-board narrow-beam antennas, whose size turns out to be in many cases incompatible with the size/mass and accommodation constraints of the hosting satellite. This paper investigates the attainable performance of large distributed arrays of antennas implemented as the ensemble of a few to many simpler sub-antennas of smaller sizes, carried by one (small) satellite each. The sub-antennas can in their turn be implemented like (regular) 2D arrays of simple radiating elements, realizing an overall (distributed) antenna architecture that we call "Formation of Arrays" (FoA). The satellites that implement this radiating architecture need to be relatively close to each other and constitute a formation of flying objects, to be coordinated and controlled as a whole. In this paper, we develop a theoretical analysis of an FoA antenna, and we show how to take advantage of this new technology to improve network throughput in a multi-beam S-band mobile communication network with low-earth or geostationary orbiting satellites directly providing 5G-like communication services to hand-held user terminals.

description: To address the lack of user-friendly software needed to simplify the utilization of model data across Heliophysics, the Community Coordinated Modeling Center (CCMC) at NASA Goddard Space Flight Center has developed a model-agnostic method via Kamodo for users to easily access and utilize model data in their workflows. By abstracting away the broad range of file formats and the intricacies of interpolation on specialized grids, this approach significantly lowers the barrier to model data access and utilization for the community while adding exciting new capabilities to their tool boxes. This paper describes the direct interfaces to the model data, called model readers, and a basic introduction on how to use them. Additionally, we detail the planned approach for including custom interpolation codes, and include current progress on specialized visualization developments. The CCMC is maintaining Kamodo as an official NASA open-sourced software to enable and encourage community collaboration.

description: Fluctuation dynamos occur in most turbulent plasmas in astrophysics and are the prime candidates for amplifying and maintaining cosmic magnetic fields. A few analytical models exist to describe their behaviour but they are based on simplifying assumptions. For instance the well-known Kazantsev model assumes an incompressible flow that is delta-correlated in time. However, these assumptions can break down in the interstellar medium as it is highly compressible and the velocity field has a finite correlation time. Using the renewing flow method developed by Bhat and Subramanian (2014), we aim to extend Kazantsev's results to a more general class of turbulent flows. The cumulative effect of both compressibility and finite correlation time over the Kazantsev spectrum is studied analytically. We derive an equation for the longitudinal two-point magnetic correlation function in real space to first order in the correlation time $τ$ and for an arbitrary degree of compressibility (DOC). This generalised Kazantsev equation encapsulates the original Kazantsev equation. In the limit of small Strouhal numbers $St \propto τ$ we use the WKB approximation to derive the growth rate and scaling of the magnetic power spectrum. We find the result that the Kazantsev spectrum is preserved, i.e. $M_k(k)\sim k^{3/2}$. The growth rate is also negligibly affected by the finite correlation time; however, it is reduced by the finite magnetic diffusivity, and the DOC together.

description: The connection between the Leggett-Garg inequality and optimal scenarios from the point of view of quantum metrology is investigated for perfect and noisy general dichotomic measurements. In this context, we show that the Fisher information can be expressed in terms of quantum temporal correlations. This connection allows us to associate scenarios with relatively high Fisher information to scenarios in which the Leggett-Garg inequality is violated. We thus demonstrate a qualitative and, to some extent, quantitative link between measurement invasiveness and metrological performance. Finally, we illustrate our results by using a specific model for spin systems.

description: Along with the rising prevalence of inflammatory bowel disease (IBD) [Crohn’s disease (CD) and ulcerative colitis (UC)], biological therapies need an update/insight. This review included randomized controlled trials (RCTs) from PubMed database (2000–October 2022) of approved biologics and small molecules with primary outcome analysis on efficacy (clinical response/remission/mucosal healing) and/or adverse events (AEs). Considered for this review under biologics classes are TNF-α inhibitors, leukocyte trafficking inhibitors, and anti IL-12/IL-23; and under small molecules are Janus-kinase inhibitors, and sphingosine-1-phosphate receptor modulators. In CD, clinical response and remission were better with tofacitinib (61.23%) and infliximab (44.86%), respectively, in the induction phase, and these were better with ustekinumab in the maintenance phase. In UC, the maximum rate of response, remission, and mucosal healing were obtained with infliximab during the induction phase (67.49%, 35.99%, and 60.25%, respectively). During the maintenance phase, response rate was better with ustekinumab, but remission and mucosal healing were better with vedolizumab. The combined percentage of AEs was highest with infliximab (174.45%) and least with ozanimod (23.04%), and most commonly belonged to the ‘infection and infestation system organ class (SOC).’ These efficacy and safety analyses will help in the optimization of biologic treatment in IBD.

description: Multicomponent commutations relations (MCR) describe plektons, i.e., multicomponent quantum systems with a generalized statistics. In such systems, exchange of quasiparticles is governed by a unitary matrix $Q(x_1,x_2)$ that depends on the position of quasiparticles. For such an exchange to be possible, the matrix must satisfy several conditions, including the functional Yang--Baxter equation. The aim of the paper is to give an appropriate definition of a quasi-free state on an MCR algebra, and construct such states on a class of MCR algebras. We observe a significant difference between the classical setting for bosons and fermions and the setting of MCR algebras. We show that the developed theory is applicable to systems that contain quasiparticles of opposite type. An example of such a system is a two-component system in which two quasiparticles, under exchange, change their respective types to the opposite ones ($1\mapsto 2$, $2\mapsto1$). Fusion of quasiparticles means intuitively putting several quasiparticles in an infinitely small box and identifying the statistical behaviour of the box. By carrying out fusion of an odd number of particles from the two-component system as described above, we obtain further examples of quantum systems to which the developed theory is applicable.
On the Dichotomy between Normal and Dwarf Ellipticals

description: Using images from the SDSS DR13 library, we examine the structural properties of 374 bright (classed E0 to E6) and dwarf ellipticals (classed dE(nN) to dE(N)). The sample combines a multicolor sample of bright ellipticals (252 galaxies with $M_g < -20$) with a new sample of faint ellipticals (60 galaxies with $M_g > -20$) which overlaps the dwarf elliptical sample (62 galaxies) in luminosity and size. The faint ellipticals extend the linear structural correlations found for bright ellipticals into parameter space not occupied by dwarf ellipticals indicating a dichotomy exists between the two types. In particular, many faint ellipticals have significantly higher effective surface brightnesses compared to dE's which eliminates any connection at a set stellar mass. Template analysis of the three subsets of ellipticals demonstrates that the bright and faint ellipticals follow the same trends of profile shape (weak homology), but that dwarf ellipticals form a separate and distinct structural class with lower central surface brightnesses and extended isophotal radii.

description: In this paper, we study energies and $g$-factors for a large number of levels of Th I. We found that the accuracy of CI-MBPT can be substantially improved by using multiple adjustment parameters, which are introduced to regulate the second-order MBPT corrections for single valence energies and Coulomb interaction. The results for energies and $g$-factors are in excellent agreement with experiment, with accuracy sufficient to positively assign theoretical states of given angular momentum and parity to experimental levels. This theory will be further developed in the future to treat other, even more complicated actinides such as U I.

description: We examine the onset of turbulence in Waleffe flow -- the planar shear flow between stress-free boundaries driven by a sinusoidal body force. By truncating the wall-normal representation to four modes, we are able to simulate system sizes an order of magnitude larger than any previously simulated, and thereby to attack the question of universality for a planar shear flow. We demonstrate that the equilibrium turbulence fraction increases continuously from zero above a critical Reynolds number and that statistics of the turbulent structures exhibit the power-law scalings of the (2+1)-D directed percolation universality class.

Strain-induced inter-vortex interaction and vortex lattices in tetragonal superconductors

Year: 2016
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: In superconductors with strong coupling between superconductivity and elasticity manifested in a strong dependence of transition temperature on pressure, there is an additional contribution to inter-vortex interactions due to the strain field generated by vortices. When vortex lines are along the $c$ axis of a tetragonal crystal, a square vortex lattice (VL) is favored at low vortex densities, because the vortex-induced strains contribution to the inter-vortex interactions is long range. At intermediate magnetic fields, the triangular lattice is stabilized. The triangular lattice evolves to the square lattice upon increasing magnetic field, and eventually the system locks to the square structure. We argue, however, that as $B$ approaches $H_{c2}$ the elastic inter-vortex interactions disappear faster than the standard London interactions, so that VL should return to the triangular structure. Our results are compared to VLs observed in the heavy fermion superconductor $\mathrm{CeCoIn_5}$.

description: Electrosurgical unit (ESU) is integral to the endoscopy unit. The proper knowledge of the Mode with setting is essential for good therapeutic outcomes and the safety of the patients. ESU generates high-frequency electric current, which could perform cutting and coagulation for various therapeutic interventions. We review the proper settings for common endoscopic interventions like hemostasis, polypectomy, sphincterotomy, and advanced procedures like endoscopic ultrasound-guided cysto-gastrostomy, bile duct drainage, and endoscopic Ampullectomy. We review the various waveforms of ESU in practice in endoscopy, including special conditions like patients with pacemakers. Knowledge of the waveforms’ duty cycle and crest factor is necessary. A high-duty cycle and lower crest factor lead to a good cutting effect on the tissue. Endocut is the most commonly used Mode in ESU in endoscopic practices like sphincterotomy and polypectomy. Endocut I mode (effect 1–2, duration 3, interval 3) is used for endoscopic sphincterotomy, while Forced Coag mode (Effect 2, 60 W) controls post-sphincterotomy bleeding. Endocut Q mode (Effect 2–3, duration 1, interval 3) is used for cutting the polyp, while Forced Coag mode (Effect 2, 60 W) is used before cutting for pre-coagulation of the stalk.

description: Das Kollisionsschweißen erlaubt die Herstellung von stoffschlüssigen Verbindungen zwischen artgleichen und artungleichen Metallen mit hoher Verbundfestigkeit und weiteren vorteilhaften Verbindungseigenschaften. Allerdings ist das Prozessverständnis aufgrund der kurzen Prozesszeiten und des komplexen Zusammenspiels verschiedener physikalischer und chemischer Phänomene noch immer lückenhaft. Dadurch bestehen bei der Auslegung von Kollisionsschweißprozessen Unsicherheiten, die zu einem aufwendigen und iterativen Vorgehen führen und ein Potential zu Kosten- und Ressourceneinsparungen bieten. Das Ziel dieser Arbeit ist daher, das Prozessverständnis hinsichtlich der Prozessgrenzen, der wirkenden Fügemechanismen und der resultierenden Verbindungseigenschaften zu erhöhen, um so die Grundlage für die Auslegung von robusten und energieeffizienten Kollisionsschweißprozessen zu schaffen. Hierfür werden in einem speziell für Grundlagenuntersuchungen entwickelten Modellversuchsstand die Prozessfenster für Aluminium und Kupfer und deren Paarung unter Variation verschiedener Prozessparameter untersucht. Dabei wird der Prozess mittels eines Systems zur Hochgeschwindigkeits-Prozessbeobachtung erfasst. Die gefügten Verbunde werden hinsichtlich ihrer Fläche und Verbundfestigkeit in Abhängigkeit der Prozessgrößen analysiert. Anhand der Ergebnisse kann eine mathematische Beschreibung der Prozessgrenzen basierend auf den auftretenden Phänomenen und den relevanten Einflussgrößen hergeleitet werden. Zudem ergeben sich neue Erkenntnisse über die in verschiedenen Bereichen des Prozessfensters wirkenden Fügemechanismen sowie die resultierenden Verbindungseigenschaften hinsichtlich der gefügten Fläche und der Verbundfestigkeit. Es zeigt sich, dass die durch die Kollision entstehende Partikelwolke eine zentrale Rolle in der Wärmeverteilung zwischen der Kollisionszone und dem sich davor einstellenden Kollisionsspalt einnimmt und damit den Prozess der Verbindungsbildung beeinflusst.

description: Paternal incarceration (PI) is recognised as a severely stigmatising event that undermines social connections leaving affected children isolated and vulnerable. However, few studies have explored social group membership as a potential mediator of positive outcomes. This paper analysed data from two national contexts, Scotland and the United States, to examine the potential for social group membership in childhood to mediate the association between PI and child behavioural and emotional outcomes. Study 1 reported on cross-sectional data from the Growing Up in Scotland dataset of children aged 12 years. Study 2 used longitudinal data from the Fragile Families cohort study (USA) of children aged 9 years and then 15 years. Children and parents completed measures of PI, children's group membership, as well as positive functioning. In Study 1, a mediated indirect effect of PI on prosocial behaviour via children's group membership was observed. In Study 2, children's reported social group membership mediated the effect of PI on positive adolescent functioning longitudinally. Whilst experiences of PI at age 9 were linked with lower group membership at age 15, group membership was associated with higher levels of positive adolescent functioning. This has implications for the support families receive when a parent is incarcerated to avoid children serving sentences for ‘the sins of their fathers’.

description: Two standing-wave single-cell choke-mode damped structures with different choke dimensions which worked at 11.424 GHz were designed, manufactured and tuned by accelerator group in Tsinghua University. High power test was carried out to study choke-mode structure's properties in high gradient and related breakdown phenomenon. A single-cell structure without choke which almost has the same inner dimension as choke-mode structure was also tested as a comparison to study how the choke affects high-gradient properties. In this paper, we report on the latest status of the high power test, including various observations and the experimental results.

description: We consider pure SU(2) Yang-Mills theory on four-dimensional de Sitter space dS$_4$ and construct a smooth and spatially homogeneous magnetic solution to the Yang-Mills equations. Slicing dS$_4$ as ${\mathbb R}\times S^3$, via an SU(2)-equivariant ansatz we reduce the Yang-Mills equations to ordinary matrix differential equations and further to Newtonian dynamics in a double-well potential. Its local maximum yields a Yang-Mills solution whose color-magnetic field at time $τ\in{\mathbb R}$ is given by $\tilde{B}_a=-\frac12 I_a/(R^2\cosh^2\!τ)$, where $I_a$ for $a=1,2,3$ are the SU(2) generators and $R$ is the de Sitter radius. At any moment, this spatially homogeneous configuration has finite energy, but its action is also finite and of the value $-\frac12j(j{+}1)(2j{+}1)π^3$ in a spin-$j$ representation. Similarly, the double-well bounce produces a family of homogeneous finite-action electric-magnetic solutions with the same energy. There is a continuum of other solutions whose energy and action extend down to zero.

description: Based on previous studies in a single particle system in both the integrable [Jarzynski, Quan, and Rahav, Phys.~Rev.~X {\bf 5}, 031038 (2015)] and the chaotic systems [Zhu, Gong, Wu, and Quan, Phys.~Rev.~E {\bf 93}, 062108 (2016)], we study the the correspondence principle between quantum and classical work distributions in a quantum many-body system. Even though the interaction and the indistinguishability of identical particles increase the complexity of the system, we find that for a quantum many-body system the cumulative quantum work distribution still converges to its classical counterpart in the semiclassical limit. Our results imply that there exists a correspondence principle between quantum and classical work distributions in an interacting quantum many-body system, especially in the large particle number limit, and further justify the definition of quantum work via two point energy measurements in quantum many-body systems.

description: Bovine mastitis is one of the most significant causes of economic losses for the dairy industry. On the other hand, public health authorities advise prudent use of antibiotics because they could promote bacterial resistance and leave residues in food chain. The dairy industry could benefit from the development of safe antimicrobial agents and bacteriocins could be attractive alternatives to antibiotics. Due to the safety of Lactic acid bacteria (LAB), their bacteriocins have the potential to be used as antimicrobials in veterinary clinical application. We analyzed the efficacy of antibacterial substances produced by bacteriocinogenic Lactococcus lactis subsp. lactis strains against contagious and environmental mastitis pathogens. Thereafter, we investigated how lactococcal strains or their bacteriocins could influence mammary gland innate immune response in vitro. Out of 65 LAB strains tested, 3 were active against mastitis pathogens: 2 strains produced Nisin, one Lacticin 481 and in addition a novel molecule with likely antibacterial activity. To analyze the immune response of mammary epithelial cells when stimulated with lactococcal strains or bacteriocins, a stabilized epithelial cell line, BME-UV1, was used. Both lactococcal live cultures and their antibacterial products were shown to modulate the non-specific immune response of BME-UV1 cells: Lysozyme and N-acetil-?-D-glucosaminidase excretion were overall enhanced by bacteriocins and live-culture treatments, while intracellular amounts were unaffected by treatments. Proinflammatory cytokine expression of treated BME-UV1 was similar to that observed in control cells, except for Lactococcus lactis subsp. lactis SL153. Such strain induced a significant reduction of TNF? transcriptional level. The stimulation of enzyme secretion due to the administration of lactococci or of their antibacterial products, with potential enhancement of pathogens cleaning, can be of interest for the prevention of intra mammary infections. In addition, Lactococcus lactis subsp. lactis SL153 strain could be advantageous for its potential anti-inflammatory properties and could be of interest for the development of intra-mammary probiotic treatments.

description: We derive rigorously the reduced dynamical laws for quantized vortex dynamics of the nonlinear Schrödinger equation on the torus with non-vanishing momentum when the vortex core size ε \to 0. The reduced dynamical laws are governed by a Hamiltonian flow driven by a renormalized energy. A key ingredient is to construct a new canonical harmonic map to include the effect from the non-vanishing momentum into the dynamics. Finally, some properties of the reduced dynamical law are discussed.
