description: For a general class of lattice-spin systems, we prove that an abstract Gaussian concentration bound implies positivity of lower relative entropy density. As a consequence we obtain uniqueness of translation-invariant Gibbs measures from the Gaussian concentration bound in this general setting. This extends earlier results from [Chazottes-Moles-REdig-Ugalde] with a different and very short proof.

description: A physical map of the chromosome of Neisseria gonorrhoeae FA1090 has been constructed. Digestion of strain FA1090 DNA with NheI, SpeI, BglII, or PacI resulted in a limited number of fragments that were resolved by contour-clamped homogeneous electric field electrophoresis. The estimated genome size was 2,219 kb. To construct the map, probes corresponding to single-copy chromosomal sequences were used in Southern blots of digested DNA separated on pulsed-field gels, to determine how the fragments from different digests overlapped. Some of the probes represented identified gonococcal genes, whereas others were anonymous cloned fragments of strain FA1090 DNA. By using this approach, a macrorestriction map of the strain FA1090 chromosome was assembled, and the locations of various genetic markers on the map were determined. Once the map was completed, the repeated gene families encoding Opa and pilin proteins were mapped. The 11 opa loci of strain FA1090 were distributed over approximately 60% of the chromosome. The pil loci were more clustered and were located in two regions separated by approximately one-fourth of the chromosome.

description: In the past few decades, the modern design philosophy of structural engineering has gradually shifted from preventing building collapse and loss of lives to high-performance objectives. However, traditional construction materials (e.g., concrete, wood, and steel) may not meet some of the high-performance structural design objectives under extreme disasters. The increasing demand for high-performance objectives has motivated the exploration of advanced structural materials. As a special type of advanced metallic material, shape memory alloys (SMAs) have been developed vigorously toward structural engineering in recent years. SMAs can withstand large strains and still recover the initial shape via heating (i.e., shape memory effect) or unloading (i.e., superelasticity). Both properties have different application prospects in the construction sector. This Special Issue has collected 30 high-quality research articles that can be categorized into three different groups: material and mechanical behavior of SMAs, shape memory effect of SMAs for prestressing and strengthening of structures, and SMA-based devices for energy dissipation and self-centering earthquake-resilient structures. Through systematic analysis of the existing research studies, this editorial summarizes the current state of knowledge and suggests future research directions and potentials for SMAs in construction.

description: Using the H$α$ observations from the New Vacuum Solar Telescope at Fuxian Solar Observatory, we focus on the fine structures of three confined flares and the issue why all the three flares are confined instead of eruptive. All the three confined flares take place successively at the same location and have similar morphologies, so can be termed homologous confined flares. In the simultaneous images obtained by the Solar Dynamics Observatory, many large-scale coronal loops above the confined flares are clearly observed in multi-wavelengths. At the pre-flare stage, two dipoles emerge near the negative sunspot, and the dipolar patches are connected by small loops appearing as arch-shaped H$α$ fibrils. There exists a reconnection between the small loops, and thus the H$α$ fibrils change their configuration. The reconnection also occurs between a set of emerging H$α$ fibrils and a set of pre-existing large loops, which are rooted in the negative sunspot, a nearby positive patch, and some remote positive faculae, forming a typical three-legged structure. During the flare processes, the overlying loops, some of which are tracked by activated dark materials, do not break out. These direct observations may illustrate the physical mechanism of confined flares, i.e., magnetic reconnection between the emerging loops and the pre-existing loops triggers flares and the overlying loops prevent the flares from being eruptive.

description: Piliated Neisseria gonorrhoeae are known to be transformed less readily if transforming DNA competes with DNA containing the 10-bp sequence GCCGTCTGAA. It has been postulated that the 10-bp sequence is a recognition sequence which is required for efficient DNA uptake. We show that the presence of various forms of this 10-bp sequence results in increased uptake of double-stranded DNA into a DNase-resistant state and allows genetic transformation by an otherwise nontransformable plasmid.

description: Billions of Radio-Frequency Identification (RFID) passive tags are produced yearly to identify goods remotely. New research and business applications are continuously arising, including recently localization and sensing to monitor earth surface processes. Indeed, passive tags can cost 10 to 100 times less than wireless sensors networks and require little maintenance, facilitating years-long monitoring with ten's to thousands of tags. This study reviews the existing and potential applications of RFID in geosciences. The most mature application today is the study of coarse sediment transport in rivers or coastal environments, using tags placed into pebbles. More recently, tag localization was used to monitor landslide displacement, with a centimetric accuracy. Sensing tags were used to detect a displacement threshold on unstable rocks, to monitor the soil moisture or temperature, and to monitor the snowpack temperature and snow water equivalent. RFID sensors, available today, could monitor other parameters, such as the vibration of structures, the tilt of unstable boulders, the strain of a material, or the salinity of water. Key challenges for using RFID monitoring more broadly in geosciences include the use of ground and aerial vehicles to collect data or localize tags, the increase in reading range and duration, the ability to use tags placed under ground, snow, water or vegetation, and the optimization of economical and environmental cost. As a pattern, passive RFID could fill a gap between wireless sensor networks and manual measurements, to collect data efficiently over large areas, during several years, at high spatial density and moderate cost.

Exact weak bosonic zero modes in a spin/fermion chain

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We study an exactly solvable one-dimensional spin-$\frac{1}{2}$ model which can support weak zero modes in its ground state manifold. The spin chain has staggered XXZ-type and ZZ-type spin interaction on neighboring bonds and is thus dubbed the (XXZ,Z) chain. The model is equivalent to an interacting fermionic chain by Jordan-Wigner transformation. We study the phase diagram of the system and work out the conditions and properties of its weak zero modes. In the fermion chain representation, these weak zero modes are given by even-order polynomials of Majorana fermion operators and are thus bosonic. The fermionic chain Hamiltonian contains only fermion hopping and interaction terms and may have potential realization in experiments.

description: Mutations that reduce the net positive charge within the hydrophilic segments of the signal peptides of several prokaryotic exported proteins can result in a reduction in the rate of protein export, as well as a reduction in protein synthesis (M. N. Hall, J. Gabay, and M. Shwartz, EMBO J. 2:15-19, 1983; S. Inouye, X. Soberon, T. Franceschini, K. Nakamura, K. Itakura, and M. Inouye, Proc. Natl. Acad. Sci. USA 79:3438-3441, 1982; J. W. Puziss, J. D. Fikes, and P. J. Bassford, Jr., J. Bacteriol. 171:2302-2311, 1989). This result has been interpreted as evidence that the hydrophilic segment is part of a mechanism that obligatorily couples translation to protein export. We have investigated the role of the hydrophilic segment of the Escherichia coli maltose-binding protein (MBP) signal peptide in the export and synthesis of MBP. Deletion of the entire hydrophilic segment from the MBP signal peptide resulted in a defect in MBP export, as well as a dramatic reduction in total MBP synthesis. Suppressor mutations that lie upstream of the malE coding region were isolated. These mutations do not affect MBP export but instead were shown to partially restore MBP synthesis by increasing the efficiency of MBP translational initiation. In addition, analysis of a series of substitution mutations in the second codon of certain malE alleles demonstrated that MBP export and synthesis can be independently affected by mutations in the hydrophilic segment. Finally, analysis of alterations in the hydrophilic segment of the ribose-binding protein signal peptide fused to the mature moiety of the MBP has revealed that the role of the hydrophilic segment in the export process can be functionally separated from any role in translation. Taken together, these results strongly suggest that the hydrophilic segment of the MBP signal peptide is not involved in a mechanism that couples MBP translation to export and argue against the presence of a mechanism that obligatorily couples translation to protein export in Escherichia coli.

description: Внешняя политика Си Цзиньпина характеризуется как постепенным отходом в дипломатической практике от принципа Дэн Сяопина «таогуан янхуэй»(скрывать свои возможности и держаться в тени), так и сменой «языка дипломатии» появлением новых концепций и терминов, которыми описываются реалии современного мира и действия Китая на международной арене. Некоторые привычные термины получают новое толкование, что не всегда замечается внешними наблюдателями. В статье в качестве примера рассматривается вопрос о содержании термина «рациональный» (хэли) в современном китайском внешнеполитическом дискурсе. Авторы приходят к выводу, что китайская трактовка рациональности имеет глубокие национальные корни. Выдвигая гипотезу о том, что это является свидетельством поиска Китаем собственной «большой стратегии», авторы обозначают ее основные черты и высказывают предложения об основных направлениях дальнейших исследований в этой области.

description: In this paper we consider a simplest two-dimensional reduction of the remarkable three-dimensional Hirota-Ohta system. The Lax pair of the Hirota-Ohta system was extended to a Lax triad by adding extra third linear equation, whose compatibility conditions with the Lax pair of the Hirota-Ohta imply another remarkable systems: the Kulish-Sklyanin system (KSS) together with its first higher commuting flow, which we can call as vector complex MKdV. This means that any common particular solution of these both two-dimensional integrable systems yields a corresponding particular solution of the three-dimensional Hirota-Ohta system. Using the dressing Zakharov-Shabat method we derive the $N$-soliton solutions of these systems and analyze their interactions, i.e. derive explicitly the shifts of the relative center-of-mass coordinates and the phases as functions of the discrete eigenvalues of the Lax operator. Next we relate to these NLEE system of Hirota--Ohta type and obtain its $N$-soliton solutions

description: It is believed that one or more basic residues at the extreme amino terminus of precursor proteins and the lack of a net positive charge immediately following the signal peptide act as topological determinants that promote the insertion of the signal peptide hydrophobic core into the cytoplasmic membrane of Escherichia coli cells with the correct orientation required to initiate the protein export process. The export efficiency of precursor maltose-binding protein (pre-MBP) was found to decrease progressively as the net charge in the early mature region was increased systematically from 0 to +4. This inhibitory effect could be further exacerbated by reducing the net charge in the signal peptide to below 0. One such MBP species, designated MBP-3/+3 and having a net charge of -3 in the signal peptide and +3 in the early mature region, was totally export defective. Revertants in which MBP-3/+3 export was restored were found to harbor mutations in the prlA (secY) gene, encoding a key component of the E. coli protein export machinery. One such mutation, prlA666, was extensively characterized and shown to be a particularly strong suppressor of a variety of MBP export defects. Export of MBP-3/+3 and other MBP species with charge alterations in the early mature region also was substantially improved in E. coli cells harboring certain other prlA mutations originally selected as extragenic suppressors of signal sequence mutations altering the hydrophobic core of the LamB or MBP signal peptide. In addition, the enzymatic activity of alkaline phosphatase (PhoA) fused to a predicted cytoplasmic domain of an integral membrane protein (UhpT) increased significantly in cells harboring prlA666. These results suggest a role for PrlA/SecY in determining the orientation of signal peptides and possibly other membrane-spanning protein domains in the cytoplasmic membrane.

description: In dealing with the problem of recognition of handwritten character patterns of varying shapes and sizes, selection of a proper feature set is important to achieve high recognition performance. The current research aims to evaluate the performance of the convex hull based feature set, i.e. 125 features in all computed over different bays attributes of the convex hull of a pattern, for effective recognition of isolated handwritten Bangla basic characters and digits. On experimentation with a database of 10000 samples, the maximum recognition rate of 76.86% is observed for handwritten Bangla characters. For Bangla numerals the maximum success rate of 99.45%. is achieved on a database of 12000 sample. The current work validates the usefulness of a new kind of feature set for recognition of handwritten Bangla basic characters and numerals.

description: The pathogenic Neisseria species are capable of utilizing transferrin as their sole source of iron. A neisserial transferrin receptor has been identified and its characteristics defined; however, the biochemical identities of proteins which are required for transferrin receptor function have not yet been determined. We identified two iron-repressible transferrin-binding proteins in Neisseria gonorrhoeae, TBP1 and TBP2. Two approaches were taken to clone genes required for gonococcal transferrin receptor function. First, polyclonal antiserum raised against TBP1 was used to identify clones expressing TBP1 epitopes. Second, a wild-type gene copy was cloned that repaired the defect in a transferrin receptor function (trf) mutant. The clones obtained by these two approaches were shown to overlap by DNA sequencing. Transposon mutagenesis of both clones and recombination of mutagenized fragments into the gonococcal chromosome generated mutants that showed reduced binding of transferrin to whole cells and that were incapable of growth on transferrin. No TBP1 was produced in these mutants, but TBP2 expression was normal. The DNA sequence of the gene encoding gonococcal TBP1 (tbpA) predicted a protein sequence homologous to the Escherichia coli and Pseudomonas putida TonB-dependent outer membrane receptors. Thus, both the function and the predicted protein sequence of TBP1 were consistent with this protein serving as a transferrin receptor.

description: Here, we compare the material quality of AlxIn1-xN layers deposited on Si with different crystallographic orientations, (100) and (111), via radio-frequency (RF) sputtering. To modulate their Al content, the Al RF power was varied from 0 to 225 W, whereas the In RF power and deposition temperature were fixed at 30 W and 300oC, respectively. X-ray diffraction measurements reveal a c-axis-oriented wurtzite structure with no phase separation regardless of the Al content (x = 0-0.50), which increases with the Al power supply. The surface morphology of the AlxIn1-xN layers improves with increasing Al content and it is similar for samples grown on both Si substrates (the root-mean-square roughness decreases from 12 nm to 2.5 nm). Furthermore, from TEM images we notice a similar grain-like columnar morphology and defect density on samples deposited on both Si substrates under the same conditions. Simultaneously grown AlxIn1-xN-on-sapphire samples point to a residual n-type carrier concentration in the 1020-1021 cm-3 range. The optical band gap energy of these layers evolves from 1.75 eV to 2.56 eV with increasing Al content, consistent with the blue shift of their low-temperature photoluminescence. In general, the material quality of the AlxIn1-xN films on Si is similar for both crystallographic orientations. Nonetheless, samples deposited on sapphire show an improved structural and morphological characteristic likely due to the lower difference in lattice constants between the nitride and the sapphire substrate.

description: Spectral clustering became a popular choice for data clustering for its ability of uncovering clusters of different shapes. However, it is not always preferable over other clustering methods due to its computational demands. One of the effective ways to bypass these computational demands is to perform spectral clustering on a subset of points (data representatives) then generalize the clustering outcome, this is known as approximate spectral clustering (ASC). ASC uses sampling or quantization to select data representatives. This makes it vulnerable to 1) performance inconsistency (since these methods have a random step either in initialization or training), 2) local statistics loss (because the pairwise similarities are extracted from data representatives instead of data points). We proposed a refined version of $k$-nearest neighbor graph, in which we keep data points and aggressively reduce number of edges for computational efficiency. Local statistics were exploited to keep the edges that do not violate the intra-cluster distances and nullify all other edges in the $k$-nearest neighbor graph. We also introduced an optional step to automatically select the number of clusters $C$. The proposed method was tested on synthetic and real datasets. Compared to ASC methods, the proposed method delivered a consistent performance despite significant reduction of edges.

Статья содержит характеристику основных направлений противостояния ad hock (в каждом конкретном случае) «коллективного Запада» формирующемуся широкому российско-китайскому альянсу. Автор отмечает, что на сегодняшний день можно констатировать наличие реальных предпосылок для еще большего укрепления существующего де-факто российско-китайского стратегического партнерства, на фоне которого особенно явственны устремления новой администрации США спровоцировать политический раскол между Россией и Китаем. Высказывается вывод, что развитие взаимоотношений между РФ, КНР и США, скорее всего, будет иметь крайне неровный характер, в результате чего могут возникать локальные военные конфликты разной политической напряженности.

description: HMf, a histone-related protein from Methanothermus fervidus, was found to bind preferentially to a DNA that is intrinsically bent as a result of the presence of phased oligo(dA) tracts. The intergenic regions in M. fervidus DNA are A+T rich and frequently contain oligo(dA) tracts, some of which may have the size and phasing required to create a net bending in one direction. The binding of HMf to bent DNA could play a direct role in gene expression and stabilization of the genome of this organism.

description: Overproduction of the sn-glycerol-3-phosphate acyltransferase in Escherichia coli leads to incorporation of this integral membrane protein into ordered tubular arrays within the cell. Freeze-fracture-etch shadowing was performed on suspensions of partially purified tubules and whole bacteria. This procedure revealed the presence of ridges and grooves defining a set of long-pitch left-handed helical ridges. The long-pitch helices represented chains of acyltransferase dimers. Tubules observed within the cell were often closely packed, with an apparent alignment of grooves and ridges in adjacent tubules. Fracture planes passing through the tubules indicated the presence of a bilayer structure, with some portion of the enzyme being associated with the membrane. The major portion of the enzyme extended from the hydrophilic surface, forming a large globular structure that, in favorable views, displayed a central cavity facing the cytoplasm. Computer analysis of shadowed tubules revealed that the left-handed helices were six stranded, with a pitch of 1,050 A (105.0 nm) and a spacing of 75 A (7.5 nm) between acyltransferase dimers along the chains. Analysis of the predicted secondary structure failed to reveal obvious transmembrane segments, suggesting that very little of the protein was inserted into the bilayer.

description: The modern quantum theory of magnetism in solids is getting commonly derived using Green's functions formalism. The popularity draws itself from remarkable opportunities to capture the microscopic landscape of exchange interactions, starting from a tight-binding representation of the electronic structure. Indeed, the conventional method of infinitesimal spin rotations, considered in terms of local force theorem, opens vast prospects of investigations regarding the magnetic environment, as well as pairwise atomic couplings. However, this theoretical concept practically does not devoid of intrinsic inconsistencies. In particular, naturally expected correspondence between single and pairwise infinitesimal spin rotations is being numerically revealed to diverge. In this work, we elaborate this question on the model example and canonical case of bcc iron. Our analytical derivations discovered the principal preference of on-site magnetic precursors if the compositions of individual atomic interactions are in focus. The problem of extremely slow or even absent spatial convergence while considering metallic compounds was solved by suggesting the original technique, based on reciprocal space framework. Using fundamental Fourier transform-inspired interconnection between suggested technique and traditional spatial representation, we shed light on symmetry breaking in bcc Fe on the level of orbitally decomposed total exchange surrounding.

Против тех стран, которые проводят независимую от Соединенных Штатов политику, будут использоваться методы «информационной войны». А для смены политических режимов в неугодных для США странах может быть использована «стратегия непрямых действий». Политика США по использованию «мягкосило-вого» арсенала в целях сохранения мировой гегемонии порождает нестабильность в мире и создает угрозу для безопасности государств-членов ШОС.
Umgang verschiedener Gemeinde-Sozialdienste des Kantons Luzern mit dem Zusammenhang zwischen Armut und Gesundheit

Year: 2024

description: Diese Bachelorarbeit untersucht den Umgang verschiedener Sozialdienste des Kantons Luzern
mit dem Zusammenhang von Armut und Gesundheit in ihrer Arbeit mit Sozialhilfebeziehenden.
Basierend auf der Studie "Gesundheit von Sozialhilfebeziehenden", die im Auftrag des
Bundesamtes für Gesundheit (BAG) durchgeführt wurde, wird aufgezeigt, dass
Sozialhilfebeziehende in der Schweiz einen signifikant schlechteren Gesundheitszustand und ein
risikoreicheres Gesundheitsverhalten als die restliche Bevölkerung aufweisen. Ziel der Arbeit ist
es, die bestehenden Praktiken der Sozialdienste zu analysieren und Optimierungsmöglichkeiten
zu identifizieren, um die Gesundheit von Sozialhilfebeziehenden zu verbessern. Hierzu wurden
qualitative Befragungen von Sozialdiensten durchgeführt, die die Wahrnehmung des
Zusammenhangs zwischen Armut und Gesundheit, die aktuellen Praktiken und die
Herausforderungen in der Betreuung von Sozialhilfebeziehenden beleuchten. Die Ergebnisse
zeigen, dass der Zusammenhang zwischen Armut und Gesundheit in den Sozialdiensten teilweise
erkannt und berücksichtigt wird, jedoch eine adäquate Bearbeitung des Themas aufgrund
zeitlicher und finanzieller Ressourcen oft eingeschränkt ist. Zur Verbesserung der
Gesundheitsversorgung werden konkrete Massnahmen und Strategien vorgeschlagen, die
sowohl die individuelle Beratung als auch die strukturelle Unterstützung durch die Institutionen
umfassen. Abschliessend enthält die Bachelorarbeit Empfehlungen zur besseren
Berücksichtigung gesundheitlicher Aspekte in der Sozialhilfe, mit dem Ziel die gesundheitlichen
Ungleichheiten zu verringern und die Lebensqualität der Betroffenen nachhaltig zu verbessern.

description: In an effort to make an inventory of the tRNA genes of Mycoplasma pneumoniae, a DNA fragment was found to contain a sequence that can be folded into a hairpin structure very similar to that of the 4.5S RNA of Escherichia coli. Recombinant plasmids carrying this region were able to complement E. coli strains that were deficient in 4.5S RNA. S1 mapping showed that the mature transcript is only 79 nucleotides long.

description: The two-parameter Minkowski like inequality written for composite quantum system state is obtained for arbitrary Hermitian nonnegative matrix with trace equal to unity. The inequality can be used as entropic and information inequality for density matrix of noncomposite finite quantum system, e.g., for a single qudit state. The analogs of strong subadditivity condition for the single qudit is discussed in context of obtained Minkowski like inequality.

description: Several software packages for relativistic cosmological simulations that do not fully implement the Einstein equation have recently been developed. Two of the free-licensed ones are inhomog and gevolution. A key question is whether globally emergent volume evolution that is faster than that of a Friedmannian reference model results from the averaged effects of structure formation. Checking that emergent volume evolution is correctly modelled by the packages is thus needed. We numerically replace the software's default random realisation of initial seed fluctuations by a fluctuation of spatially constant amplitude in a simulation's initial conditions. The average volume evolution of the perturbed model should follow that of a Friedmannian expansion history that corresponds to the original Friedmannian reference solution modified by the insertion of the spatially constant perturbation. We derive the equations that convert from the perturbed reference solution to the effective solution. We find that inhomog allows emergent volume evolution correctly at first order through to the current epoch. For initial conditions with a resolution of $N = 128^3$ particles and an initial non-zero extrinsic curvature invariant $I_i = 0.001$, inhomog matches an exact Friedmannian solution to -0.0058% (Einstein-de Sitter, EdS) or -0.0033% (LCDM). We find that gevolution models the decaying mode to fair accuracy, and excludes the growing mode by construction. For $N = 128^3$ and an initial scalar potential $Φ$ = 0.001, gevolution is accurate for the decaying mode to 0.012% (EdS) or 0.013% (LCDM). We conclude that this special case of an exact non-linear solution for a perturbed Friedmannian model provides a robust calibration for relativistic cosmological simulations.

description: The recently emerged spectral clustering surpasses conventional clustering methods by detecting clusters of any shape without the convexity assumption. Unfortunately, with a computational complexity of $O(n^3)$, it was infeasible for multiple real applications, where $n$ could be large. This stimulates researchers to propose the approximate spectral clustering (ASC). However, most of ASC methods assumed that the number of clusters $k$ was known. In practice, manual setting of $k$ could be subjective or time consuming. The proposed algorithm has two relevance metrics for estimating $k$ in two vital steps of ASC. One for selecting the eigenvectors spanning the embedding space, and the other to discover the number of clusters in that space. The algorithm used a growing neural gas (GNG) approximation, GNG is superior in preserving input data topology. The experimental setup demonstrates the efficiency of the proposed algorithm and its ability to compete with similar methods where $k$ was set manually.

description: A total of 508 random clones from five Mycoplasma genitalium genomic libraries were partially sequenced and analyzed. This resulted in the identification of 291 unique contigs. Sequence information from these clones (100,993 nucleotides), representing approximately 17% of this pathogen's genome, was analyzed by comparison to the DNA and protein sequence data bases. The frequency with which clones could be identified, by virtue of possessing homology to another data base entry, was 46%. Sequence analysis indicated the following. (i) The M. genitalium genome contains many genes involved in various metabolic processes. (ii) Repetitive DNA may comprise as much as 4% of this genome. (iii) The MgPa adhesin gene may be the result of horizontal transfer from an unknown origin. (iv) Not all dinucleotide pairs are present in this genome at the expected frequency. (v) This genome potentially encodes approximately 390 proteins and makes very efficient use of its limited amount of DNA. In addition, this study allowed us to estimate the number of genes involved with various cellular functions.
