description: In 1960 Schwinger [J. Schwinger, Proc.Natl.Acad.Sci. 46 (1960) 570- 579] proposed the algorithm for factorization of unitary operators in the finite M dimensional Hilbert space according to a coprime decomposition of M. Using a special permutation operator A we generalize the Schwinger factorization to every decomposition of M. We obtain the factorized pairs of unitary operators and show that they obey the same commutation relations as Schwinger's. We apply the new factorization to two problems. First, we show how to generate two kq-like mutually unbiased bases for any composite dimension. Then, using a Harper-like Hamiltonian model in the finite dimension M = M1M2, we show how to design a physical system with M1 energy levels, each having degeneracy M2.

The methylation of sugar mercaptals
Creators: name: Tanaka, Yukio
Publisher: name: University of British Columbia
Year: 2011

description: Sugar mercaptals were partially methylated with Purdie's reagents in tetrahydrofuran as a solvent, and the relative reactivity of hydroxyl groups was determined by estimation of the ratio of mono-0̲-methyl ethers. The highest reactivity of the 2-hydroxyl group, followed by that of the 3-hydroxyl group, was accounted for by the inductive effect of the mercaptal group and the variation of the ratios among the sugar mercaptals was further explained by the intramolecular hydrogen bonding in the zig-zag conformation of sugar mercaptals. The exceptionally high reactivity of the 3-hydroxyl group of D̳-galactose diethyl mercaptal was also shown to be explicable in terms of the hydrogen bonding. An appreciable reactivity of the primary hydroxyl groups was noted and attributed to the least steric hindrance at this position. A mechanism for the Purdie methylation was proposed. Mg values of various mono-0̲-methyl sugars were recorded and some modifications in the separation of mono-0̲-methyl sugars were also described. 5-0̲-Methyl-L̳-arabinose and two crystalline derivatives were synthesized for the first time, and 2-0̲-methyl-L̳-arabonolactone, hitherto known as a sirup, was crystallized.

Weaving Economics The Early Modern Idea of a Limitless World and the Birth of Modern Economics
Creators: name: Lingg, Andreas Friedolin
Publisher: name: Zenodo
Year: 2023

description: The use of the terms cameralism and mercantilism is controversial. This is especially true when applied to the early modern period, the gray area in the history of ideas between medieval scholasticism and the economics of the Enlightenment. The problems are manifold. One of the most serious objections is that contemporary authors did not use these terms. They are anachronistic in nature, it is argued, and as such would have been used by economists of later eras less with descriptive than with instrumental intentions, as a means of ideological and parascientific debate. No less serious is the accusation that there was no independent economic theorizing or scholarly practice in this phase that would justify such titles or categories. These works would have been too eclectic, too undisciplined, too unsystematic, too unclearly demarcated from other fields of knowledge, too strongly rooted in traditions such as the medieval princely mirror, too weak in their will to penetrate the economic sphere and to explore its laws and regularities. In the early modern period, we are dealing with a phase in the history of economic thought that in many respects eludes modern scientific categories and ways of thinking. Ordered scholarly discourses, faculties, universities and clearly delineated genre boundaries - all of these existed only to a very limited extent in the field of economic debates. The use of concepts such as cameralism or mercantilism in this era therefore lead to gross simplifications that obscure rather than reveal their subject matter. It takes a different language and a different way of thinking to discern dogma-historical patterns here. Developing these is a worthwhile goal, since this epoch was, according to the thesis, a critical phase in the development of modern economics. This article argues that to understand the processes and the importance of this time, one must go to the level of individual arguments. It is necessary to draw the attention away from works and authors to the realm of particular statements and beliefs that circulated, as will be shown, first in the environment of a few trades and sectors - luxury crafts, long-distance trade, colonial politics, and precious metal mining - to eventually find a way, across all national borders, into scholarly economic writing. The discourse of economic theory subsequently underwent a major transformation in Europe in the 15th and 16th centuries. At that time, parts of it changed from a static household-theory, oriented towards control and parsimony, to a speculative advice literature, which was based on the idea of a (in principle) limitless world of economic possibility. In order to understand the economics of the following centuries it is vital to look at these early argumentative threads and to observe how they were repeatedly rewoven to finally form the fabric of modern economics.
Catheter ablation as first-line treatment for ventricular tachycardia in patients with structural heart disease and preserved left ventricular ejection fraction: a systematic review and meta-analysis

description: In this systematic review and meta-analysis, we aim to evaluate the efficacy and safety of catheter ablation as the first-line treatment of ventricular tachycardia (VT) in patients with structural heart disease (SHD) and preserved left ventricular ejection fraction (LVEF). Patients with SHD are particularly susceptible to VT, a condition that increases the risk of sudden cardiac death (SCD). Implantable cardioverter-defibrillators (ICDs) can terminate VT and prevent SCD but do not prevent VT recurrence. The efficacy and safety of CA as a first-line treatment in SHD patients with preserved LVEF remain unclear. We searched PubMed/Medline, EMBASE, Web of Science, and Cochrane CENTRAL for studies reporting the outcomes of CA therapy in patients with VT and preserved LVEF, published up to January 19, 2023. The primary outcome was the incidence of SCD following catheter ablation as the first-line treatment of VT in patients with SHD and preserved LVEF. Secondary outcomes included all-cause mortality, VT recurrence, procedural complications, CA success rate, and ICD implantation after catheter ablation. We included seven studies in the meta-analysis, encompassing a total of 920 patients. The pooled success rate of catheter ablation was 84.6% (95% CI 67.2–93.6). Complications occurred in 6.4% (95% CI 4.0–9.9) of patients, and 13.9% (95% CI 10.1–18.8) required ICD implantation after ablation. VT recurrence was observed in 23.2% (95% CI 14.8–34.6) of patients, while the rate of sudden cardiac death (SCD) was 3.1% (95% CI 1.7–5.6). The overall prevalence of all-cause mortality in this population was 5% (95% CI 1.8–13). CA appears promising as a first-line VT treatment in patients with SHD and preserved LVEF, especially for monomorphic hemodynamically tolerated VT. However, due to the lack of direct comparisons with ICDs and anti-arrhythmic drugs, further research is needed to confirm these findings.

description: We investigate how nonlinearity and topological disorder affect the energy relaxation of local kicks in coarse-grained network models of proteins. We find that nonlinearity promotes long-range, coherent transfer of substantial energy to specific, functional sites, while depressing transfer to generic locations. Remarkably, transfer can be mediated by the self-localization of discrete breathers at distant locations from the kick, acting as efficient energy-accumulating centers.

description: We determine the slope of the near infrared extinction power law (A$_λ \propto λ^{-α}$) for 8 regions of the Galaxy between l$\sim27^{\circ}$ and $\sim100^{\circ}$. UKIDSS Galactic Plane Survey data are compared, in colour-colour space, with Galactic population synthesis model data reddened using a series of power laws and convolved through the UKIDSS filter profiles. Monte Carlo simulations allow us to determine the best fit value of $α$ and evaluate the uncertainty. All values are consistent with each other giving an average extinction power law of $α$=2.14$^{+0.04}_{-0.05}$. This is much steeper than most laws previously derived in the literature from colour excess ratios, which are typically between 1.6 and 1.8. We show that this discrepancy is due to an inappropriate choice of filter wavelength in conversion from colour excess ratios to $α$ and that effective rather than isophotal wavelengths are more appropriate. In addition, curved reddening tracks, which depend on spectral type and filter system, should be used instead of straight vectors.

description: Evaluating diagnostic test accuracy during epidemics is difficult due to an urgent need for test availability, changing disease prevalence and pathogen characteristics, and constantly evolving testing aims and applications. Based on lessons learned during the SARS-CoV-2 pandemic, we introduce a framework for rapid diagnostic test development, evaluation, and validation during outbreaks of emerging infections. The framework is based on the feedback loop between test accuracy evaluation, modelling studies for public health decision-making, and impact of public health interventions. We suggest that building on this feedback loop can help future diagnostic test evaluation platforms better address the requirements of both patient care and public health.

description: We use macroscopic holes drilled in a bulk YBCO superconductor to probe its magnetic properties in the volume of the sample. The sample is subjected to an AC magnetic flux with a density ranging from 30mT to 130mT and the flux in the superconductor is probed by miniature coils inserted in the holes. In a given hole, three different penetration regimes can be observed: (i) the shielded regime, where no magnetic flux threads the hole; (ii) the gradual penetration regime, where the waveform of the magnetic field has a clipped sine shape whose fundamental component scales with the applied field; and (iii) the flux concentration regime, where the waveform of the magnetic field is nearly a sine wave, with an amplitude exceeding that of the applied field by up to a factor of two. The distribution of the penetration regimes in the holes is compared with that of the magnetic flux density at the top and bottom surfaces of the sample, and is interpreted with the help of optical polarized light micrographs of these surfaces. We show that the measurement of the magnetic field inside the holes can be used as a local characterization of the bulk magnetic properties of the sample.

description: Possible laser processes in battery manufacturing are quite diverse regarding the control of electrochemical characteristics: LIPSS on current collector surfaces are used to adjust the adhesion of composite electrodes to current collectors, laser surface patterning turns ceramic-coated separator materials into superwicking with regard to electrolyte wetting properties, and laser structuring of composite thick film electrodes is applied to generate 3D electrode architectures with shortened lithium-ion diffusion pathways. In the field of cathode thick film development, secondary particles with nanoscaled primary particles are used and ultrafast laser ablation is applied to pattern the composite electrodes to optimize the lithium ion diffusion kinetics by enlarging the active material surface with a view to reducing cell polarization, which develops at high battery power. This enables high energy batteries to be upgraded for operation at high power. In the field of anode development for electromotive vehicles, efforts are being made to develop silicon anodes in order to significantly increase the energy density. In addition, the issue of fast charging, mainly influenced by the anode architecture, is a major topic in research and industrial development. Silicon nanoparticles are used and combined with graphite particles in a binder matrix. The large volume change as a result of the lithiation of silicon during battery operation requires laser structuring of the composite electrodes in order to counteract mechanical degradation. Analogous to cathode materials, the lithium diffusion kinetics for anodes are also significantly enhanced by the applied 3D battery concept. The impact of laser structuring and modification of battery materials on the electrochemical performance with respect to the nanoscale is of considerable relevance for future applications in battery manufacturing.

description: The entanglement entropy of the incompressible states of a realistic quantum Hall system in the second Landau level are studied by direct diagonalization. The subdominant term to the area law, the topological entanglement entropy, which is believed to carry information about topologic order in the ground state, was extracted for filling factors nu = 12/5 and nu = 7/3. While it is difficult to make strong conclusions about nu = 12/5, the nu = 7/3 state appears to be very consistent with the topological entanglement entropy for the k=4 Read-Rezayi state. The effect of finite thickness corrections to the Coulomb potential used in the direct diagonalization are also systematically studied.

description: Adult playfulness describes individual differences in (re)framing situations so that they are experienced as entertaining, and/or interesting, and/or intellectually stimulating. There is increasing interest in its role for romantic life. Using the OLIW model of playfulness, we localized its facets Other-directed, Lighthearted, Intellectual, and Whimsical playfulness into systems of attachment styles and romantic jealousy. We analyzed data of 332 mixed-gender and 139 same-gender couples (Ntotal = 942). We found no robust mean differences between same-gender and mixed-gender couples (exception: same-gender couples are lower in emotional jealousy). Actor-Partner Interdependence Model analyses showed that Other-directed, Lighthearted, and Intellectual playfulness yielded negative relations to attachment insecurities in actors, but no partner effects. For jealousy, all types of playfulness related negatively to emotional jealousy, but Whimsical playfulness showed positive inclinations to cognitive and behavioral jealousy in actors. Partners reported greater cognitive jealousy when their partner was high in Lighthearted, whereas partners from Whimsical high scorers reported lower emotional jealousy. The findings are invariant between same-gender and mixed-gender couples. Our study extends the knowledge on how playfulness relates to experiences in close relationships in mixed-gender and same-gender couples. We discuss implications (e.g., Signal Theory of Playfulness) and future directions.
Curvature-induced frustration in the $XY$ model on hyperbolic surfaces

description: We study low-temperature properties of the $XY$ spin model on a negatively curved surface. Geometric curvature of the surface gives rise to frustration in local spin configuration, which results in the formation of high-energy spin clusters scattered over the system. Asymptotic behavior of the spin-glass susceptibility suggests a zero-temperature glass transition, which is attributed to multiple optimal configurations of spin clusters due to nonzero surface curvature of the system. It implies that a constant ferromagnetic spin interaction on a regular lattice can exhibit glasslike behavior without possessing any disorder if the lattice is put on top of a negatively curved space such as a hyperbolic surface.

Does auriculotherapy modulate pain threshold?
Creators: name: Nori, Stefania Lucia

description: Antonio Maria Valsalva (1666–1723) wrote the first modern anatomical description of the human ear and in 1717 published the Aura Humanus Tractatus, where he describes the treatment of toothache by scarification of antitragus. Auriculotherapy (AT) is a diagnostic and treatment method based on normalizing the body’s dysfunction through stimulation of definite points on the ear. Stimulation of a reflex point in the ear seems relieve symptoms of distant pathologies (Gori et al 2007). AT is a treatment diffusing in all over the world, and its patterns follow the principles of Chinese acupuncture, revised and updated, with Chinese and French maps of the ear; the principles of Paul Nogier (the father of Western AT) and also the principles of reflexology basing on somatotopic maps that do not recognize energetic-based stimulation, while just the evocation of a reflex stimulating precise areas of the ear. Today are used for stimulation of ear skin many different tools: finger acupressure, laser, electricity, different types of needles, magnetic balls and seeds (Nogier 1983). In our experiments AT involved the placement of vaccaria seeds on one ear, with two minute pressure and no further manipulation by the patient. The ear point used were fingers, from the French and Chinese charts. Two groups of healthy volunteers (n. = 6 for each group), 19-25 years old, participated to the study. Each subject was asked to perform an auto-algometric test (Viggiano et al., 2009) on three occasions: before, 1 hour after auricolotherapy (or sham-therapy) and 24 hours after auricolotherapy (or sham-therapy). Participants of the first group received a 2 min long session of auricolotherapy, while participants of the second group received a 2 min long session of sham-therapy, consisting of a puncture/massage above the skin of the neck. The auto-algometric test consisted of applying the subject themselves an increasing pressure with the fingertips and finger-backs of four fingers (i.e. eight sites were evaluated) against a round-shaped needle of 1 mm in diameter for two times: until a minimum pain sensation (first time, minimal test) or a maximally tolerable pain sensation were evoked (second time, maximal test). The results showed a significant greater pain threshold in the maximal test at 24 hours after the auricolotherapy compared to sham-therapy. This result indicates that auricolotherapy can increase pain tolerability, rather than affecting the minimal pain threshold.

Stereoelectronic effects on the basicities of carbonyl compounds
Creators: name: Granger, Maurice Roy
Publisher: name: University of British Columbia
Year: 2011

description: The basicities of fifteen ortho-substituted benzoic acids and five benzophenone analogues have been measured with the aim of studying the effects of stereoelectronic factors on the strengths of very weak bases. The ortho effects of the substituents on the basicities of the benzoic acids have been estimated by two methods. The first method compares the pKβH⁺ values of the corresponding ortho- and para-substituted acids and uses the difference between them as a measure of the ortho effect on the assumption that the electrical effects of substituents are equal in the ortho and para positions. The second method is that of McDaniel and Brown (10). The ortho effects of alkyl substituents are base weakening and increase in the order methyl < ethyl < i-propyl < t-butyl. These effects are attributed to the bulk effect of the substituents, and in particular, to steric inhibition of resonance in the conjugate acid. The halogen substituents, on the other hand, appear to have base strengthening ortho effects in the order F > Cl > Br > I ≃ 0, which are attributed to stabilization of the protonated acid by intra-molecular hydrogen bonding. In a similar manner, oxygen containing substituents such as methoxyl and carboxyl are base strengthening. The basicities of these benzoic acids do not follow the linear relationships of either Taft (21) or Farthing and Nam (22) which have been developed to correlate the reactions of ortho-substituted benzene derivatives, a fact which serves to emphasize the high dependence of ortho effects upon the nature of the reaction. The basicities of benzophenone analogues in which the phenyl rings are rigidly held have also been studied. The basicities were found to be in the order 9-anthrone > 2,3;6,7-dibenzotropone > 2,3;6,7-dibenzosuberone > benzophenone > 9-fluorenone. The high basicity of anthrone is attributed to the planarity of the molecule which allows a high degree of resonance in both the unprotonated and protonated species. The low basicity of fluorenone is attributed to its similarity to cyclopentadienone in which the tendency of the carbonyl group to polarize in the usual direction, and so increase the electron density on oxygen, is greatly reduced through an effort to aromatize the ring.

description: Mitophagy is a novel identified autophagic process through which defective and malfunctioning mitochondria are degraded or recycled. The balance between this process and mitochondrial biogenesis is crucial for post-mitotic neurons’ survival, as mitochondria are the primary energetic source required for the formation and function of axon terminals and dendritic spines (Amadoro et al 2014). As other cell types, neuronal populations also continually modulate size and number of these organelles, according to the variable energy demands and metabolic states throughout the entire lifetime and/or different sub-cellular compartments. In polarized neurons removal of damaged mitochondria can be a bioenergetically demanding task because these organelles need to be actively transported from the axons and dendrites in order to fuse to cell body resident lysosomes (Wang et al 2006). Physiologically aging as well as numerous human neurodegenerative disease, including Parkison’s disease, Huntington’s disease, amyotrophic lateral sclerosis and Alzheimer’s disease (AD) has been associated with alterations in quality control of neuronal mitochondria (Santos et al 2010), but still now, mitophagy pathway and its dysfunction in neudegenerative disease remain undisclosed. Data from several neurotoxic models show that mitochondria undergo to selective morphological changes in distribution, shape and interconnectivity which are hallmarks of mitophagy. These changes are typically studied at the confocal and TEM microscopes and quantified through a morphometric approach. Due to their polarized nature, neurons present a loss in the neuritic domain more pronounced in respect to the cell body compartment. In addition, morphometric analysis show that the mitochondria interconnectivity, area/perimeter ratio and elongation, major/minor axis ratio, are reduced in neurotoxic models and that these changes parallel in vivo findings from tissue derived from several neurodegenerative diseases. Thus, neurotoxic models, which are acute insults, are able to trigger mitophagy in similar way to human neurodegenerative diseases which, instead, develop the pathology in the course of several years.

description: Aging is frequently accompanied by a low-grade pro-inflammatory condition which is considered a prodrome of Alzheimer Disease (AD). Indeed a common event of aging and AD is the deposition of beta amyloid (Aß) fibrils in the central nervous system, that has been associated to cognitive decline also in normal aging. Identifying traits of amyloid aggregates are the irreversibility of their molecular interactions, the ability to propagate from one cell to another and resist to clearance mechanisms [1]. We previously reported that, in aged rats, astrocyte clasmatodendrosis promote neuron to neuron propagation of Aß-fibrils and, therefore, their prion like spread. Clasmatodendrosis is a phenomenon described in astrocytes that consists in the loss of their distal processes. It’s known that astrocytes constitutively remove Aß-fibrils from neurolemma with their cytoplasmic processes and, in pathological conditions, this activity may cause their necrosis. Moreover, they regulate microglial activity in the central nervous system. Although microglial cells are involved in Aß-fibril clearance, they have also been associated to neuronal cell death in Alzheimer Disease. In this work we found that clasmatodendrosis is associated with a decrease of astrocyte activity of Aß fibril clearance in the pyramidal layer and affects microglial phagocytic activation in the hippocampus of aged rats. To discriminate immunofluorescence signals from autofluorescence typical of amyloid aggregates on confocal acquisitions, we designed a specific method of linear unmixing. Moreover, multiphoton microscopy analyses were implemented with an innovative method of fluorescence lifetime analysis (FLIM/Phasor), suitable to discriminate multiple fluorescences. On the whole our data suggest that clasmatodendrosis consistently affects clearance mechanisms of Aß fibril in the central nervous system and foreshadow new strategies in the development of therapeutical protocols against AD.
