Many H-Copies in Graphs with a Forbidden Tree

For graphs $H$ and $F$, let $\operatorname{ex}(n, H, F)$ be the maximum possible number of copies of $H$ in an $F$-free graph on $n$ vertices. The study of this function, which generalises the well-studied Tur\'an numbers of graphs, was initiated recently by Alon and Shikhelman. We show that if $F$ is a tree then $\operatorname{ex}(n, H, F) = \Theta(n^r)$ for some integer $r = r(H, F)$, thus answering one of their questions.
Clinical Efficacy of Western Medicine Combined with Chinese Medicine for Pelvic Inflammatory Disease (Damp-Heat and Stasis Type)

Objective: This study was undertaken to evaluate the clinical efficacy of Western medicine combined with Chinese medicine for pelvic inflammatory disease (damp-heat and stasis type). Methods: Seventy-four patients who were diagnosed with pelvic inflammatory disease (damp-heat and stasis type) by our hospital during July 2021 to July 2022 were randomized into two groups: the participants in the control group received conventional Western medicine treatment, and the participants in the study group received Western medicine combined with Chinese medicine. Results: After treatment, the total effectiveness of the control group (72.98%) was significantly lower than that of the study group (94.59%), (P < 0.05); the whole blood viscosity high cut, whole blood viscosity low cut, fibrinogen and plasma viscosity of the control group were all lower than those of the study group (P < 0.05); the levels of CRP, IL-6, and TNF-? in the control group were higher and IL-2 levels in the control group were lower than those in the study group (P < 0.05). Conclusion: Western medicine combined with Chinese medicine is more effective in curing damp-heat and stasis-type pelvic inflammatory disease by improving the blood rheological indexes and lowering the level of inflammatory factors.
Origin of Streamer Material in the Outer Corona

We investigate the nature and origin of the outward-moving density inhomogeneities ("blobs") detected previously with the Large Angle and Spectrometric Coronagraph on the Solar and Heliospheric Observatory. The blobs are concentrated around the thin plasma layer that surrounds the heliospheric current sheet and that constitutes the outer streamer belt; they represent only a small, fluctuating component of the total density within the plasma sheet. As noted before in Sheeley et al., blobs are characterized by low speeds and are continually emitted from the elongated tips of helmet streamers at 3-4 R from Sun center. We suggest that both the blobs and the plasma sheet itself represent closed-field material injected into the solar wind as a result of footpoint exchanges between the stretched helmet-streamer loops and neighboring open field lines. The plasma sheet is thus threaded by newly reconnected, open magnetic field lines, which lend the white-light streamer belt its filamentary appearance. Since in situ observations at 1 AU show that the slow wind (with speeds below 500 km s−1) spreads over an angular extent much greater than the ≲3° width of the plasma sheet, we deduce that a major component of this wind must originate outside the helmet streamers (i.e., from just inside coronal holes).
Effect of substitutions on the thermoelectric figure of merit of half-Heusler phases at 800 °C

The merit of thermally stable MNiSn (M=Ti, Zr, Hf) half-Heusler phases, as n-type thermoelectric materials, for high-temperature power generation has been examined. Sb doping at the Sn site is shown to increase both the figure of merit, ZT, and the temperature at which ZT is maximized. The benefits of increased alloying at the M and Ni sites, on the thermal conductivity and thermoelectric transport properties, have also been investigated. The thermoelectric figure of merit, ZT∼0.8 at T∼800°C, for select Sb-doped MNiSn alloys was found to meet or exceed the industry benchmark set by SiGe alloys.
Friends or foe? The complementarity or substitutability of financial development and FDI, financial development, and trade openness on domestic investment

ABSTRACT This paper examines the relationship between financial development and FDI and between financial development and trade openness in boosting domestic investment. Initially, this paper examined this issue for panel data sample of 161 countries over 1995–2018. Considering the issue of aggregation bias due to heterogeneous nature of countries in the sample, this complementarity or substitutability effect between financial development and FDI as well as financial development and trade openness have further been re-examined by using 129 developing country samples. Using panel fixed effects (FE) and two-step system GMM estimation technique, the empirical results demonstrate the substitutability between financial development and FDI as well as a substitutability relationship between financial development and trade openness in driving domestic investment. The results hold for both the samples and also in alternative measures of financial development and extended specifications.
A burst model for line emission in the solar atmosphere. III - A reassessment of the assumptions of constant pressure and steady state coronal equilibrium in the solar transition region

We investigate the temperature dependence of the electron densities inferred from various spectral line diagnostics for the quiet Sun, two active regions, and the 1973 June 15 flare, all observed by NRL instruments on Skylab. We find that the common assumption of constant pressure in these solar regions is very poor, especially for the quiet Sun and the active regions, and that a constant density assumption is much closer to the observations. Such a conclusion is not contradicted by the morphology of these regions, as observed by the HRTS instrument. We also investigate the variation of the nonthermal mass motion with departures of the line formation temperature from that corresponding to ionization equilibrium
Analisis Difusi Inovasi pada Inovasi Produk Batik di Kelurahan Jenggot Dalam Mendukung Upaya Pengembangan Ekonomi Lokal Kota Pekalongan

The development of innovation in a particular area cannot be separated from the diffusion of innovation. This diffusion of innovation occurs because of the process of social interaction by related actors in the region. This is explained by Rogers (2003), that the diffusion of innovation is a process when innovation is communicated or mentioned through certain channels for a certain period of time to members of a social system, which then becomes part of the social system. With the diffusion of innovation, an area will experience changes in certain conditions due to the impact of emerging innovations, which will play a role in developing the character of the region. As happened in Jenggot village, the emergence or entry of new patterns influenced changes in the market in terms and the direction of development of the existing batik patterns in the village. Batik patterns that were originally patterned and impressed monotonously with plant and animal-based patterns are becoming more contemporary and fashionable. The diffusion of innovation helps business owners either directly or indirectly in promoting their batik products. Thus increasing the value of the batik product itself.
Nursing Assessment of Pressure Injury Risk with the Braden Scale Validated against Sensor-Based Measurement of Movement

Nursing staff assessment to accurately identify pressure injury (PrI) risk is a hallmark in PrI prevention care. Risk scores from the Braden Scale for Predicting Pressure Sore Risk© (hereafter Braden), a commonly used tool for assessing PrI risk, signal the need for preventative care. Braden Mobility, Activity, and Sensory Perception subscale subgroups associated with repositioning movement features help identify preventative strategies that minimize pressure intensity and duration. Evidence confirming subscale rating accuracy is needed. This study compared assessment score accuracy with movement data collected via accelerometer sensor. Sample included 913 nursing home residents from the Turn Everyone and Move for Pressure Ulcer Prevention (TEAM-UP) cluster randomized trial. Movements and Braden Mobility and Activity subscale scores were evaluated for significant differences and associations. Mobility subgroups explained a small-medium amount of variance in mean lying and upright movement features (0.002 ≤ R2 ≤ 0.195). Activity subgroups explained a small-medium amount of variance in mean lying, upright, and ambulating movements (0.016 ≤ R2 ≤ 0.248). Significant associations occurred among subscale subgroups and most movements. Nursing assessment ratings using Braden scale’s Mobility and Activity subscale scores are accurate indicators of actual repositioning movements and can be relied upon for PrI prevention care planning for older adults.
ON ASYMPTOTIC PROPERTIES OF A TWO DIMENSIONAL FREQUENCY ESTIMATOR

Estimating parameters of a two dimensional frequency model is an important problem in statistical signal processing. In this paper, we consider the two-dimensional frequency model in presence of an additive stationary noise. We consider two different estimators and obtain their asymptotic properties. The asymptotic properties can be used to construct confidence intervals of the unknown parameters and for testing purposes also. The small sample performances of these estimators are observed using numerical simulations.
Bicalutamide Anticancer Activity Enhancement by Formulation of Soluble Inclusion Complexes with Cyclodextrins

Bicalutamide (BCL) is a nonsteroidal antiandrogen drug that represents an alternative to castration in the treatment of prostate cancer, due to its relatively long half-life and tolerable side effects. However, it possesses a very low water solubility that can affect its oral bioavailability. In this work, we developed inclusion complexes of BCL with the highly soluble hydroxypropyl-β-cyclodextrin (HP-β-CyD) and sulfobutylether-β-cyclodextrin (SBE-β-CyD) to increase the water solubility and anticancer activity of BCL. The inclusion complexes were prepared using the freeze-drying method and were then characterized in a solid state via differential scanning calorimetry and X-ray analysis and in solution via phase-solubility studies and UV-vis and NMR spectroscopy. The BCL/HP-β-CyD and BCL/SBE-β-CyD inclusion complexes were amorphous and rapidly dissolved in water. Both the 1H-NMR spectra and molecular modeling studies confirmed the penetration of the 2-(trifluoromethyl)benzonitrile ring of BCL within the cavity of both cyclodextrins (CyDs). Due to the consistent improvement of the water solubility of BCL, the inclusion complexes showed higher antiproliferative activity toward the human prostate androgen-independent cell lines, DU-145 and PC-3, with respect to free BCL. These results demonstrate the ability of HP-β-CyD and SBE-β-CyD to complex BCL, permitting the realization of liquid formulations with potentially high oral bioavailability and/or possible parenteral administration.
Anisotropically etched deep gratings for InP/InGaAsP optical devices

We report a new grating fabrication technique for optical devices in the InP/InGaAsP system. Conventional, but very shallow, holographically defined wet etching is used to pattern ultrathin masking layers grown by chemical beam epitaxy. This is followed by selective and anisotropic wet etching, which is shown to yield exceptionally deep, narrow‐pitch gratings with reproducible profiles and dimensions.
FINITE FLAT SPACES

We say that a finite metric space $X$ can be embedded almost isometrically into a class of metric spaces $C$, if for every $\epsilon > 0$ there exists an embedding of $X$ into one of the elements of $C$ with the bi-Lipschitz distortion less then $1 + \epsilon$. We show that almost isometric embeddability conditions are equal for following classes of spaces (a) Quotients of Euclidean spaces by isometric actions of finite groups, (b) $L_2$-Wasserstein spaces over Euclidean spaces, (c) Compact flat manifolds, (d) Compact flat orbifolds, (e) Quotients of bi-invariant Lie groups by isometric actions of compact Lie groups. (This one is the most surprising.) We call spaces which satisfy this conditions finite flat spaces. The question about synthetic definition naturally arises. Since Markov type constants depend only on finite subsets we can conclude that bi-invariant Lie groups and their quotients have Markov type $2$ with constant $1$.
Canonical Generators for the Cohomology of Moduli of Parabolic Bundles on Curves

The aim of this paper is to determine generators of the rational cohomology algebras of moduli spaces of parabolic vector bundles on a curve, under some ‘primality’ conditions (see Assumptions 1.1 and 1.2) on the parabolic datum. These generators are canonical in a sense which will be made precise below. Our results are new even for usual vector bundles (i.e., vector bundles without parabolic structure) whose rank is greater than 2 and is coprime to the degree; in this case, they are generalizations of a theorem of Newstead [8], where the case of vector bundles of rank 2 and odd degree is studied. ∗On leave from the School of Mathematics, SPIC Science Foundation, Madras, India.
Coherent Lagrangian vortices: the black holes of turbulence

Abstract We introduce a simple variational principle for coherent material vortices in two-dimensional turbulence. Vortex boundaries are sought as closed stationary curves of the averaged Lagrangian strain. Solutions to this problem turn out to be mathematically equivalent to photon spheres around black holes in cosmology. The fluidic photon spheres satisfy explicit differential equations whose outermost limit cycles are optimal Lagrangian vortex boundaries. As an application, we uncover super-coherent material eddies in the South Atlantic, which yield specific Lagrangian transport estimates for Agulhas rings.
Multi-Hop RF Wireless Power Transfer for Autonomous Wireless Sensor Network

This paper is devoted to studying multi-hop wireless power transfer (WPT), which is especially applicable in autonomous wireless sensor networks. The main objective of the current work is to investigate the possibility of increasing the efficiency of WPT using a multi-hop transmission approach. The study describes the main limitations of the multi-hop RF energy transmission, analyses the possible technical solution of a multi-hop sensor node, and evaluates the performance of multi-hop WPT compared to the classical technique. The research combines RF signal transmission simulations and experimental studies. Multi-hop WPT analysis is made for the sub-GHz frequency band and two wireless nodes. Friis approximation of point-to-point signal propagation is used for simulating the multi-hop energy transmission in free space, while the method of Shooting and Bouncing Ray is used for multichannel propagation simulation. Current work expands the WPT applications by providing an approach to increase the distance of RF energy transmission for the wireless sensor nodes in the areas with lower coverage.
Large-Scale 3D Printing for Construction Application by Means of Robotic Arm and Gantry 3D Printer: A Review

Additive manufacturing technologies are becoming more popular in various industries, including the construction industry. Currently, construction 3D printing is sufficiently well studied from an academic point of view, leading towards the transition from experimental to mass large-scale construction. Most questions arise about the applicability of construction 3D printers for printing entire buildings and structures. This paper provides an overview of the different types of construction 3D printing technologies currently in use, and their fundamental differences, as well as some significant data on the advantages of using these advanced technologies in construction. A description of the requirements for composite printing is also provided, with possible issues that may arise when switching from lab-scale construction printing to mass large-scale printing. All printers using additive manufacturing technologies for construction are divided into three types: robotic arm printers, portal-type printers, and gantry 3D printers. It is noted that gantry printers are more suitable for large-scale printing since some of their configurations have the ability to construct buildings that are practically unlimited in size. In addition, all printers are not capable of printing with concrete containing a coarse aggregate, which is a necessary requirement in terms of the strength and economic feasibility of 3D printing material for large-scale applications.
Infinite Dimensional Geometry and Quantum Field Theory of Strings. II. Infinite Dimensional Noncommutative Geometry of a Self-Interacting String Field

A geometric interpretation of quantum self–interacting string ﬁeld theory is given. Relations between various approaches to the second quantization of an interacting string are described in terms of the geometric quantization. An algorythm to construct a quantum nonperturbative interacting string ﬁeld theory in the quan- tum group formalism is proposed. Problems of a metric background (in)dependence are discussed.
Moderate Treadmill Exercise Alleviates NAFLD by Regulating the Biogenesis and Autophagy of Lipid Droplet

Lipid droplet is a dynamic organelle that undergoes periods of biogenesis and degradation under environmental stimuli. The excessive accumulation of lipid droplets is the major characteristic of non-alcoholic fatty liver disease (NAFLD). Moderate aerobic exercise is a powerful intervention protecting against the progress of NAFLD. However, its impact on lipid droplet dynamics remains ambiguous. Mice were fed with 15 weeks of high-fat diet in order to induce NAFLD. Meanwhile, the mice performed 15 weeks of treadmill exercise. Our results showed that 15 weeks of regular moderate treadmill exercise alleviated obesity, insulin intolerance, hyperlipidemia, and hyperglycemia induced by HFD. Importantly, exercise improved histological phenotypes of NAFLD, including hepatic steatosis, inflammation, and locular ballooning, as well as prevented liver fat deposition and liver injury induced by HFD. Exercise reduced hepatic lipid droplet size, and moreover, it reduced PLIN2 protein level and increased PLIN3 protein level in the liver of HFD mice. Interestingly, our results showed that exercise did not significantly affect the gene expressions of DGAT1, DGAT2, or SEIPIN, which were involved in TG synthesis. However, it did reduce the expressions of FITM2, CIDEA, and FSP27, which were major involved in lipid droplet growth and budding, and lipid droplet expansion. In addition, exercise reduced ATGL protein level in HFD mice, and regulated lipophagy-related markers, including increasing ATG5, LAMP1, LAMP2, LAL, and CTSD, decreasing LC3II/I and p62, and promoting colocalization of LAMP1 with LDs. In summary, our data suggested that 15 weeks of moderate treadmill exercise was beneficial for regulating liver lipid droplet dynamics in HFD mice by inhibiting abnormal lipid droplets expansion and enhancing clearance of lipid droplets by lysosomes during the lipophagic process, which might provide highly flexible turnover for lipid mobilization and metabolism.

Progressive Multifocal Leukoencephalopathy-Immune Reconstitution Inflammatory Syndrome (PML-IRIS) Presenting with Refractory Status Epilepticus in a Patient with HIV-1

Sir, Progressive multifocal leukoencephalopathy (PML) occurs due to the re‐activation of the polyoma John Cunningham (JC) virus in immunocompromised patients although a few reports have described its occurrence in immunocompetent patients. PML may occur in up to 5% of patients with acquired immunodeficiency syndrome (AIDS). [1] After initiation of Highly active antiretroviral therapy (HAART), patients with HIV may develop a worsening attributable to immune reconstitution, termed PML‐Immune reconstitution inflammatory syndrome (IRIS). [2] Unlike PML, patients with PML‐IRIS show contrast enhancement on MRI. The prevalence of seizures in PML is up to 18% to 44%. [3] The risk for seizures is increased if PML is located adjacent to the cortex. [4] We present the first case of refractory status epilepticus (RSE) in PML‐IRIS associated with HIV infection.
Some Consequences of a Recursive Number-Theoretic Relation that is Not the Standard Interpretation of Any of its Formal Representations

We give a precise definition of a formal mathematical object as any symbol for an individual constant, predicate letter, or a function letter that can be introduced through definition into a formal mathematical language without inviting inconsistency. We then show: there is an elementary, recursive, number-theoretic relation that is not a formal mathematical object, since it is not the standard interpretation of any of its representations in Goedel's formal system P; the range of a recursive number-theoretic function does not always define a (recursively enumerable set) formal mathematical object consistently in any Axiomatic Set Theory that models P; there is no P-formula, Con(P), whose standard interpretation is unambiguously equivalent to Goedel's number-theoretic definition of "P is consistent"; every recursive number-theoretic function is not strongly representable in P; Tarski's definitions of "satisfiability" and "truth" can be made constructive, and intuitionistically unobjectionable, by reformulating Church's Thesis constructively; the classical definition of Turing machines can be extended to include self-terminating, converging, and oscillating routines; a constructive Church's Thesis implies, firstly, that every partial recursive number-theoretic function can be constructively extended as a unique total function, and, secondly, that we can define effectively computable functions that are not classically Turing-computable; Turing's and Cantor's diagonal arguments do not necessarily define Cauchy sequences.
Label-Free Optical pH Measurement Based on Chitosan-TEOS-PDMS Hydrogel Layer for Microfluidic Applications

The optical pH sensor based on smart hydrogel material was designed for use in microfluidic applications. The chitosan-tetraethyl orthosilicate (chitosan-TEOS) interpenetrating network was synthesized as a pH-sensitive part of the sensor. This chitosan-TEOS-PDMS layer was bonded by oxygen plasma treatment to a thin layer of polydimethylsiloxane (PDMS), which enabled easily integrating of the sensor layer into the microfluidic chips. Also, the thickness of this PDMS layer worked as an adjustable parameter to control the sensitivity of the sensor. In addition, the optical astigmatism method (the method used in CD/DVD optical pickup unit) was utilized to measure the pH-induced variations of the sensor layer by monitoring the laser beam profile on a charge-coupled device (CCD). The experimental results showed that the fabricated sensor responded to pH changes and became stable in less than 90 s. It showed a sensitivity of 54 and 94 pixel/pH using the spin-coated PDMS thickness of 75 and 28 $\mu \text{m}$ , respectively.
