description: We study the pion-mass dependence of the two-pion channel in the hadronic-vacuum-polarization (HVP) contribution to the anomalous magnetic moment of the muon $a_μ^\text{HVP}$, by using an Omnès representation for the pion vector form factor with the phase shift derived from the inverse-amplitude method (IAM). Our results constrain the dominant isospin-$1$ part of the isospin-symmetric light-quark contribution, and should thus allow one to better control the chiral extrapolation of $a_μ^\text{HVP}$, required for lattice-QCD calculations performed at larger-than-physical pion masses. In particular, the comparison of the one- and two-loop IAM allows us to estimate the associated systematic uncertainties and show that these are under good control.

description: The USNO-B Catalog contains spurious entries that are caused by diffraction spikes and circular reflection halos around bright stars in the original imaging data. These spurious entries appear in the Catalog as if they were real stars; they are confusing for some scientific tasks. The spurious entries can be identified by simple computer vision techniques because they produce repeatable patterns on the sky. Some techniques employed here are variants of the Hough transform, one of which is sensitive to (two-dimensional) overdensities of faint stars in thin right-angle cross patterns centered on bright ($<13 \mag$) stars, and one of which is sensitive to thin annular overdensities centered on very bright ($<7 \mag$) stars. After enforcing conservative statistical requirements on spurious-entry identifications, we find that of the 1,042,618,261 entries in the USNO-B Catalog, 24,148,382 of them ($2.3 \percent$) are identified as spurious by diffraction-spike criteria and 196,133 ($0.02 \percent$) are identified as spurious by reflection-halo criteria. The spurious entries are often detected in more than 2 bands and are not overwhelmingly outliers in any photometric properties; they therefore cannot be rejected easily on other grounds, i.e., without the use of computer vision techniques. We demonstrate our method, and return to the community in electronic form a table of spurious entries in the Catalog.

Capability, influence and international collaboration : a case study of the telecommunications satellite
Creators: name: Vos, Lynn L
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the evolution of telecommunications satellite technology since its functional inauguration a quarter century ago in order to draw some conclusions about how the distribution of capabilities affects collaboration for the use and development of global technologies. Collaboration is examined in three specific areas: collaboration for the design and development of satellite systems, for the launching of satellites, and for the use and allocation of the frequency spectrum and geostationary orbit. Special attention is given to the role of the United States in shaping collaboration in these three areas. The findings indicate that the structure and nature of international collaboration is strongly affected by the distribution of capabilities among states but that an understanding of the specific character of that collaboration requires a knowledge of other factors particular to the technology in question.

description: In this paper, spin-orbit coupling induced photovoltaic effect of cold atoms has been studied in a three-trap system which is an two-dimensional extension of a two-trap system reported previously. It is proposed here that atom coherent length is one of the important influence to the resistance of this photovoltaic battery. Current properties of the system for different geometrical structures of the trapping potentials are discussed. Numerical results show extension in the number of traps could cause current increase directly. Quantum master equation at finite temperature is used to treat this opened system. This work may give a theoretical basis for further development of the photovoltaic effect of neutral atoms.

description: The increasing prevalence and implementation of climate neutrality or net zero targets by companies is in essence a welcome development. It is an expression of greater awareness that the climate crisis requires responsible and forward-looking action by companies, and that they are willing to take on this responsibility. However, neutrality targets can hide the fact that society in general and many companies in particular still face enormous challenges in overcoming the climate crisis. In most cases, there is a long and arduous path between formulating targets and achieving them, with the latter requiring the realisation of a wide range of measures. The Wuppertal Institute therefore proposes the recommendations for setting and implementing net zero targets.
DSP: Dual Soft-Paste for Unsupervised Domain Adaptive Semantic Segmentation

description: Unsupervised domain adaptation (UDA) for semantic segmentation aims to adapt a segmentation model trained on the labeled source domain to the unlabeled target domain. Existing methods try to learn domain invariant features while suffering from large domain gaps that make it difficult to correctly align discrepant features, especially in the initial training phase. To address this issue, we propose a novel Dual Soft-Paste (DSP) method in this paper. Specifically, DSP selects some classes from a source domain image using a long-tail class first sampling strategy and softly pastes the corresponding image patch on both the source and target training images with a fusion weight. Technically, we adopt the mean teacher framework for domain adaptation, where the pasted source and target images go through the student network while the original target image goes through the teacher network. Output-level alignment is carried out by aligning the probability maps of the target fused image from both networks using a weighted cross-entropy loss. In addition, feature-level alignment is carried out by aligning the feature maps of the source and target images from student network using a weighted maximum mean discrepancy loss. DSP facilitates the model learning domain-invariant features from the intermediate domains, leading to faster convergence and better performance. Experiments on two challenging benchmarks demonstrate the superiority of DSP over state-of-the-art methods. Code is available at \url{https://github.com/GaoLii/DSP}.

description: Apparently, some form of local superconducting pairing persists to temperatures well above the maximum observed $T_c$ in underdoped cuprates, \textit{i.e.} $T_c$ is suppressed due to the small phase stiffness. With this in mind, we consider the following question -- Given a system with a high pairing scale $Δ_0 $ but with $T_c$ reduced by phase fluctuations, can one design a composite system in which $T_c$ approaches its mean-field value, $T_c\to T_{MF}\approx Δ_0/2\$? Here, we study a simple two component model in which a "metallic layer" with $Δ_0=0$ is coupled by single-particle tunneling to a "pairing layer" with $Δ_0 >0 $ but zero phase stiffness. We show that in the limit that the bandwidth of the metal is much larger than $Δ_0$, $T_c$ of the composite system can reach the upper limit $T_c \approxΔ_0/2$.

description: Entanglement between quantum network nodes is often produced using intermediary devices - such as heralding stations - as a resource. When scaling quantum networks to many nodes, requiring a dedicated intermediary device for every pair of nodes introduces high costs. Here, we propose a cost-effective architecture to connect many quantum network nodes via a central quantum network hub called an Entanglement Generation Switch (EGS). The EGS allows multiple quantum nodes to be connected at a fixed resource cost, by sharing the resources needed to make entanglement. We propose an algorithm called the Rate Control Protocol (RCP) which moderates the level of competition for access to the hub's resources between sets of users. We proceed to prove a convergence theorem for rates yielded by the algorithm. To derive the algorithm we work in the framework of Network Utility Maximization (NUM) and make use of the theory of Lagrange multipliers and Lagrangian duality. Our EGS architecture lays the groundwork for developing control architectures compatible with other types of quantum network hubs as well as system models of greater complexity.

description: By assuming that ultra dense hybrid neutron stars are endowed with a distribution of electric charge, we study the corresponding twin star solutions and their properties resulting from a sharp first order transition from confined hadronic to a deconfined quark phase. Two distinct quark matter equations of state with increasing stiffness are considered and the values for the maximum gravitational masses of the hadronic and hybrid twin configurations are obtained for different values of the total electric charge. Interestingly, our calculations indicate that sharp transitions make charged twin hybrid stars more massive than their neutral counterparts, and that the {$\SI{2}{M_{\odot}}$ constraint from PSR J0740+6620} is surpassed for standard values of electric charge and can be considered stable only satisfying $\partial M/\partial ε_0 > 0$. In particular, our charged stellar models reach masses even higher than the unknown compact object measured in the GW190814 event.

description: We demonstrate a novel way to efficiently and very robust create an entanglement between an atomic and a photonic qubit. A single laser beam is used to excite one atomic ensemble and two different spatial modes of scattered Raman fields are collected to generate the atom-photon entanglement. With the help of build-in quantum memory, the entanglement still exists after 20.5 $μ$s storage time which is further proved by the violation of CHSH type Bell's inequality. Our entanglement procedure is the building block for a novel robust quantum repeater architecture [Zhao et al, Phys. Rev. Lett. 98, 240502 (2007)]. Our approach can be easily extended to generate high dimensional atom-photon entanglements.

description: In the mountains of the Eastern Alpine Arc, a material that does not correspond to their geological genesis has been inserted: reinforced concrete. This very compound is the first witness in the history of the construction of the majority of the bunkers built around the Second World War as an integral part of the defensive line called Vallo alpino del Littorio, which expanded from Ventimiglia to Fiume. The construction of this historical infrastructure was not straightforward and suffered several setbacks, especially due to the turnover of the military leaders who controlled it. This line of defence remained manned and guarded during the Cold War period, in the four decades preceding the fall of the Berlin Wall, and was dismantled only in 1993. It can be said that these works are pieces of foundational architecture in the mountain landscapes of the twentieth century. Observing the Friulian mountains. it is difficult to identify both the line of the barriers and the colossal infrastructure work. The bunkers were hidden using the "camouflage" technique. Geology and military architecture establish a very close relationship with this type of construction. This relationship becomes emblematic in the case of the bunker Sbarramento del III° Sistema in Cavazzo Carnico (Udine). There are only a few cases of recovery and reuse of these buildings, and one of them is Opera 2 – Sbarramento Invillino Ovest, which is always located on the Carnic Prealps (Udine). However, this bunker, once made accessible, is used only sporadically. These war machines, scattered as they are not only in the heights but also between rivers and on the coasts, perpetuating their silent isolation, always maintain some sort of non-involvement in the flows of the contemporary city. The only possibility to restore the right value to these buildings, showing their muscles firmly planted in the ground, is to make them part of an active architectural and testimonial system, thanks to a broad and multidisciplinary point of view which will allow a large-scale reactivation of the territory.

description: We investigate the options for imposing flavor symmetries on a minimal renormalizable non-supersymmetric $\mathrm{SU}(5)$ grand unified theory, without introducing additional flavor-related fields. Such symmetries reduce the number of free parameters in the model and therefore lead to more predictive models. We consider the Yukawa sector of the Lagrangian, and search for all possible flavor symmetries. As a result, we find 25 distinct realistic flavor symmetry cases, with $\mathbb{Z}_2$, $\mathbb{Z}_3$, $\mathbb{Z}_4$, and $\mathrm{U}(1)$ symmetries, and no non-Abelian cases.

description: The inventories carried in a supply chain as a strategic tool to influence the competing firms are considered to be strategic inventories (SI). We present a two-period game-theoretic supply chain model, in which a singular manufacturer supplies products to a pair of identical Cournot duopolistic retailers. We show that the SI carried by the retailers under dynamic contract is Pareto-dominating for the manufacturer, retailers, consumers, the channel, and the society as well. We also find that the retailer's SI, however, can be eliminated when the manufacturer commits wholesale contract or inventory holding cost is too high. In comparing the cases with and without downstream competition, we also show that the downstream Cournot duopoly undermines the retailers in profits, but benefits all others.

description: The Paris Agreement is the latest collective declaration of ambition to keep global warming below two degrees Celsius, compared to pre-industrial levels. In theory, Parties to the Agreement should collectively decarbonize the carbon-emitting human activities to reach carbon neutrality; however, the greenhouse gas emissions continue to rise, and the leading global banks continue to invest billions of dollars into fossil fuels. Literature on the Paris Agreement gives very mixed reviews about effectiveness of its provisions. There is an ongoing heated debate whether the agreement will actually live up to expectations; whether it will be successful at preventing the temperature rise. This publication aims to contribute to the ongoing debate by conducting an interdisciplinary research on strengths and weaknesses of the document (discussing ambiguousness in metrics; national pledges; capacity-building; and the concepts of undue burden, sovereignty, non-punitive approach). It aims to analyze Paris Agreement in multi-disciplinary manner, by putting a human being at the center of attention: linking economics, psychology, and behavior to natural sciences. A failure to recognize the fundamental interconnectivity of these fields of studies might lead to failure of Paris Agreement, and failure to contain the global rising temperatures.This publication closely and critically evaluates provisions of Paris Agreement and insists that under the current circumstances, the objectives it sets will not be met. Only by first discussing anthropogenic traits and human socio-economic orders it is ultimately possible to address the origins of the current ineffectiveness and maladaptation. Understanding the drivers behind the human behavior (like the anthropogenic tendency to plan short-term instead of long-term, a direct outcome of hunter-gatherer mentality) is a prerequisite to coming up with ways to insure success of the Paris Agreement. The economic activity is an intrinsic part of human social interaction, and the rising temperatures are a byproduct of the intensified and the increased human activity; the challenge is to let human activity continue, but mitigate excessive emissions by conducting systemic changes and reforms in politics, technology, and cultures. Recognizing the non-punitive and non-interventional nature of the Agreement, to increase our chances of survival it is necessary to focus on overcoming the information gap about the climate problems, by bringing together policy making and science; by openly admitting that the world is currently not on track.

description: Of the effective ways to have successful interactions, the proper use of words could be mentioned. The vocabulary items chosen by the speaker can act as conversation starters. Consciously chosen vocabulary items that are attractive and functional enough could make a profound impact on the audience. The success of the speaker's utterance is effectively ensured by a web of vocabulary items that may have been carefully picked up in accordance with the theme of the discussion and the audience's taste. The present study, therefore, sets forth the concept of "language decoration" as an interdisciplinary approach in establishing effective communications. Language decoration means ornamenting the content and form of the utterance so as to affect the audience significantly. In fact, language decoration can reveal individuals' identity and personality and is firmly rooted within their linguistic competence. In view of the importance of thinking, emotion, sense, and culture in conversations and considering the fact that "postlocution" moves beyond communicative competence, the current study endeavors to put forward literary ornaments, psychological ornaments, cultural ornaments, sensory ornaments at the forefront of language decoration. Moreover, it advances this view that through cogbination (cognition+combination), emobination (emotion+combination), culbination (culture+combination), and sensbination (sense+combination), people could decorate their utterances and consequently, improve their communicative performance.

description: Single molecule data made of on and off events are ubiquitous. Famous examples include enzyme turnover, probed via fluorescence, and opening and closing of ion-channel, probed via the flux of ions. The data reflects the dynamics in the underlying multi-substate on-off kinetic scheme (KS) of the process, but the determination of the underlying KS is difficult, and sometimes even impossible, due to the loss of information in the mapping of the mutli-dimensional KS onto two dimensions. A way to deal with this problem considers canonical (unique) forms. (Unique canonical form is constructed from an infinitely long trajectory, but many KSs.) Here we introduce canonical forms of reduced dimensions that can handle any KS (i.e. also KSs with symmetry and irreversible transitions). We give the mapping of KSs into reduced dimensions forms, which is based on topology of KSs, and the tools for extracting the reduced dimensions form from finite data. The canonical forms of reduced dimensions constitute a powerful tool in discriminating between KSs.

Implementation of curriculum : actual use compared to intended use of an environmental education programme
Creators: name: Worthing, Donald Craig
Publisher: name: University of British Columbia
Year: 2010

description: In education over the past decade there has been a growing awareness of the relationship between the implementation process and programme effectiveness. Studies have shown that this relationship is affected by teachers who often modify aspects of a programme during the implementation process. This study investigated the implementation by teachers of the environmental programme ENCORE. Leithwood's model of 'Dimensions of Curriculum Innovations' allowed examination of aspects of the ENCORE programme considered necessary for effective implementation by the developer (as stated or implied in the ENCORE handbook). The dimensions explored were content, materials, teaching strategy, time allotment. A questionnaire was developed to examine the aspects of each dimension and was administered to teachers using ENCORE. To determine the extent to which each dimension of the programme is being implemented a modified version of Leithwood's model including programme objectives and underlying programme assumptions was used. Leithwood's model was combined with a modified version of Hall & Loucks' model of 'Levels of Use' of an innovation. Four levels of use of the ENCORE programme dimensions were considered: becoming familiar with, attempting to apply, determining effectiveness of, and modifying the programme. Questionnaire items examined levels of teacher use. The survey instrument was verified in terms of format validity, construct validity and integrity of response.

description: Several pulsar timing array (PTA) experiments such as NANOGrav and PPTA recently reported evidence of a gravitational wave (GW) background at nano-Hz frequency band. This signal can originate from scalar-induced gravitational waves (SIGW) generated by the enhanced curvature perturbation. Production of SIGW is expected to be accompanied by formation of primordial black holes (PBH), which can emit GW through binary mergers. Here we perform a joint likelihood inference on PTA datasets in combination with existing limits on PBH abundance and GW density, we derive full Bayesian posteriors for PBH distribution and relevant PBH merger signal. Our results show that analysis using PTA data alone implies significant overproduction of PBHs, and accounting for current PBH limits causes visible shifts in SIGW posterior. If PTA signals are indeed of SIGW origin, the required curvature perturbation amplitude produces PBHs in a narrow mass window of $[6 \times 10^{-2}, 2 \times 10^{-1}]\ m_\odot$. Mergers of these PBHs can leave a strong GW signature in $[10^{-3}, 10^5]$ Hz frequency range, to be detectable at upcoming interferometers such as LISA, aLIGO, Einstein Telescope, DECIGO and BBO, etc. This offers a multi-frequency opportunity to further scrutinize the source of the observed PTA signal and can potentially improve current PBH constraints by up to 5 orders of magnitudes.

description: With advances in quantum computing, new opportunities arise to tackle challenging calculations in quantum field theory. We show that trotterized time-evolution operators can be related by analytic continuation to the Euclidean transfer matrix on an anisotropic lattice. In turn, trotterization entails renormalization of the temporal and spatial lattice spacings. Based on the tools of Euclidean lattice field theory, we propose two schemes to determine Minkowski lattice spacings, using Euclidean data and thereby overcoming the demands on quantum resources for scale setting. In addition, we advocate using a fixed-anisotropy approach to the continuum to reduce both circuit depth and number of independent simulations. We demonstrate these methods with Qiskit noiseless simulators for a $2+1$D discrete non-Abelian $D_4$ gauge theory with two spatial plaquettes.

A note on ensemble holography for rational tori

Year: 2021
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study simple examples of ensemble-averaged holography in free compact boson CFTs with rational values of the radius squared. These well-known rational CFTs have an extended chiral algebra generated by three currents. We consider the modular average of the vacuum character in these theories, which results in a weighted average over all modular invariants. In the simplest case, when the chiral algebra is primitive (in a sense we explain), the weights in this ensemble average are all equal. In the non-primitive case the ensemble weights are governed by a semigroup structure on the space of modular invariants. These observations can be viewed as evidence for a holographic duality between the ensemble of CFTs and an exotic gravity theory based on a compact $U(1) \times U(1)$ Chern-Simons action. In the bulk description, the extended chiral algebra arises from soliton sectors, and including these in the path integral on thermal AdS$_3$ leads to the vacuum character of the chiral algebra. We also comment on wormhole-like contributions to the multi-boundary path integral.

urn:lsid:zoobank.org:act: D423198E-EA1D-44F1-A1E3-C1E31F6FDC4E
Fig. 10, Table 5
Diagnosis
Species of Stroboceras with weakly depressed, rounded-trapezoidal whorl profile (ww/wh ~1.45), venter strongly flattened, ventrolateral shoulder angular with sharp longitudinal ridges. Whorls not embracing. Whorl profile with wide longitudinal groove on the outer flank near the ventrolateral margin.
Etymology
From the Latin ‘ mane ’, meaning ‘early, morning’ and referring to the stratigraphically early occurrence of the species.
Type material
Holotype ALGERIA • Mouydir, south of Oued Temertasset (locality MOU-Y); Argiles de Teguentour (Lower Pericyclus-Progoniatites Assemblage; early late Tournaisian); Korn et al. 2002 Coll.; illustrated in Fig. 10A; MB.C.30458.1.
Paratype ALGERIA • Mouydir, south of Oued Temertasset (locality MOU-Y); Argiles de Teguentour (Lower Pericyclus-Progoniatites Assemblage; early late Tournaisian); Korn et al. 2002 Coll.; MB.C.30458.2.
Description
Holotype MB.C.30458.1 is a phragmocone fragment with about 22 mm conch diameter; it is partly embedded in a haematite nodule (Fig. 10A) and was sectioned for the study of the whorl profile. The conch is discoidal and evolute (ww/dm=0.51; uw/dm= 0.45). The whorl profile is rounded-trapezoidal with almost flat venter separated from the convex flanks by an angular ventrolateral shoulder. Next to this shoulder is a shallow, wide longitudinal groove (Fig. 10B). The whorls apparently do not touch each other, but this may be caused by dissolution of the shell wall.
The suture line has a very broad external lobe, an angular ventrolateral saddle in the area of the ventrolateral shoulder and a flat, somewhat undulating lateral lobe (Fig. 10C). The siphuncle has a subcentral position.
Remarks
Stroboceras mane sp. nov. is an ancestral species of the genus and differs from almost all other species by the non-embracing whorls. Another distinguishing criterion is the very weak formation of longitudinal ridges and grooves.

description: В статье рассмотрены проблемы сторон и тенденции рынка труда. Каждый человек в своей профессионально-трудовой деятельности занимался поиском работы или ищет работу. Причины поиска индивидуальны, но главное это денежное вознаграждение за свой труд и реализация профессиональной личности. На рынке труда две стороны: работник и работодатель. Как правило, каждая сторона наделена определенными правами и обязанностями. Даже на этапе поиска цели и задачи различны, но при этом есть ряд требований, выставленных каждой стороной. В связи с этим возникает ряд проблем с каждой стороны при согласии на выставленные условия. Рынок труда в РФ регламентируется Трудовым кодексом Российской Федерации и постоянно усовершенствуется с новыми требованиями рынка и новыми ситуациями на нём. Все изменения на рынке труда входят в систему рынков, которые изменяются под влиянием различных причин, в частности, сильное влияние оказывает экономический кризис. На рынок труда оказали влияние ряд кризисов (2008 – 2010 2014 гг.), каждый период внёс свои коррективы и дал новый виток развития и сворачивания. В целом можно отметить, что рынок труда нуждается в равной степени и в высококвалифицированном и низкоквалифицированном труде. Процессы автоматизации труда постоянно и постепенно входят каждый день в трудовые процессы и оказывают своё влияние на трансформацию образования и адаптивности к условиям работодателей. Проблемы сторон (работник и работодатель) есть, они решаемы и эволюционируют в своем процессе. Многие процессы отмирают, а новые неизвестные требуют иного мышления. Рынок труда становится глобальным.
A Monte Carlo comparison of regression estimators in the presence of autocorrelation and collinearity

description: In time series regression modelling, first-order autocorrelated errors are often a problem. When the data also suffers from collinear independent variables, generalized least squares estimation is no longer the best alternative to ordinary least squares. The Monte Carlo simulation illustrates that ridge estimation using data transformed according to the generalized least squares method provides estimates of the regression coefficients which are superior to generalized least squares, ridge and ordinary least squares estimates. The analysis of a set of 'typical' econometric data further supports the application of this method referred to as generalized ridge when both autocorrelation and collinearity are present.
Magnetically Torqued Thin Accretion Disks

description: We compute the properties of a geometrically thin, steady accretion disk surrounding a central rotating, magnetized star. The magnetosphere is assumed to entrain the disk over a wide range of radii. The model is simplified in that we adopt two (alternate) ad hoc, but plausible, expressions for the azimuthal component of the magnetic field as a function of radial distance. We find a solution for the angular velocity profile tending to corotation close to the central star, and smoothly matching a Keplerian curve at a radius where the viscous stress vanishes. The value of this ''transition'' radius is nearly the same for both of our adopted B-field models. We then solve analytically for the torques on the central star and for the disk luminosity due to gravity and magnetic torques. When expressed in a dimensionless form, the resulting quantities depend on one parameter alone, the ratio of the transition radius to the corotation radius. For rapid rotators, the accretion disk may be powered mostly by spin-down of the central star. These results are independent of the viscosity prescription in the disk. We also solve for the disk structure for the special case of an optically thick alpha disk. Our results are applicable to a range of astrophysical systems including accreting neutron stars, intermediate polar cataclysmic variables, and T Tauri systems.

description: Aggregation of the nanoparticles is a natural phenomena due to various biological and physical parameters but these aggregates are highly unstable. If aggregates would have been stable then it might be useful for some biomedical applications. To study the optical properties and photothermal heat generation of stable aggregates of the metal nanopartilces, we present a forced synthesis of aggregates of small gold nanorods in a mixture of Dulbecco's Modified Eagle's medium (DMEM) and Bovine Serum Albumin (BSA). We synthesised hexadecyltrimethylammonium bromide (CTAB) coated gold nanorods and then prepared the stable aggregates to study the optical characteristics of these aggregates. Absorption spectra of aggregates show the redshift compared to the monodispersive gold nanorods and confirm that the shape and size of aggregate depend on the amount of BSA in DMEM as well as on the concentration of CTAB in the stock solution of the gold nanorods suspension. The higher concentration of the BSA in DMEM and lower concentration of CTAB of monodispersive gold nanorod suspension causes greater redshift. We tuned the well defined plasmonic absorption resonance peaks of the aggregates of gold nanorods up to the second biological therapeutic window. We studied the stability of the synthesised aggregates of gold nanorods for up to one week and found that the aggregates were stable for atleast one week. A photothermal study of these aggregates was also carried out using high power broadband near-infrared light source. Aggregates were also photothermally stable which warrants their repeated use for such applications. The photothermal conversion efficiency of the these stable gold nanorod aggregates were higher than its monodispersive form of the nanorods.

description: Conditions for harmonic analysis in generalized Orlicz spaces have been studied over the past decade. One approach involves the generalized inverse of so-called weak $Φ$-functions. It featured prominently in the monograph Orlicz Spaces and Generalized Orlicz Spaces [P. Harjulehto and P. Hästö, Lecture Notes in Mathematics, vol. 2236, Springer, Cham, 2019]. While generally successful, the inverse function formulation of the decay condition (A2) in the monograph contains a flaw, which we explain and correct in this note. We also present some new results related to the conditions, including a more general result for the density of smooth functions.

description: We report four $Σ$'s and three $Λ$'s, in the 1500 - 1800 MeV region, as two meson - one baryon S-wave $(1/2)^+$ resonances. We solve Faddeev equations in the coupled channel approach. The invariant mass of one of the meson-baryon pairs and that of the three particles have been varied and peaks in the squared three body $T$-matrix have been found very close to the existing $S$ = -1, $J^P= 1/2^+$ low lying baryon resonances. The input two-body $t$-matrices for meson-meson and meson-baryon interaction have been calculated by solving the Bethe-Salpeter equation with the potentials obtained in the chiral unitary approach.
