The controllability of a thermoelastic plate problem revisited

In this paper, the controllability for a thermoelastic plate problem with a rotational inertia parameter is considered under two scenarios. In the first case, we prove the exact and approximate controllability when the controls act in the whole domain. In the second case, we prove the interior approximate controllability when the controls act only on a subset of the domain. The distributed controls are determined explicitly by the physical constants of the plate in the first case, while this is no longer possible in the second case as the relation (79) is no longer valid. In this case, we propose an approximation of the control function with an error that tends to zero. By means of a powerful and systematic approach based on spectral analysis, we improve some already existing results on the optimal rate of the exponential decay and on the analyticity of the associated semigroup.
Increase in TPSB2 and TPSD1 Expression in Synovium of Hip Osteoarthritis Patients Who Are Overweight

While research suggests that increasing body mass index (BMI) is a risk factor for hip osteoarthritis (HOA), the mechanisms of this effect are not fully understood. Tryptases are among the main proteases found in mast cells (MCs) and contribute to OA pathology. TPSB2, which encodes β-tryptase, is increased in the synovium of overweight and obese knee OA patients. However, it remains unclear whether tryptase in the synovium of HOA is increased with increasing BMI. Here, we investigated tryptase genes (TPSB2 and TPSD1) in the synovium of overweight HOA patients. Forty-six patients radiographically diagnosed with HOA were allocated to two groups based on BMI, namely normal (<25 kg/m2) and overweight (25–29.99 kg/m2). TPSB2 and TPSD1 expression in the synovium of the two groups was compared using real-time polymerase chain reaction. To compare TPSB2 and TPSD1 expression in MCs between the groups, we isolated the MC-rich fraction (MC-RF) and MC-poor fraction (MC-PF), extracted using magnetic isolation. TPSB2 and TPSD1 expression was increased in the overweight group compared with the normal group. Expression of both genes in the MC-RF was significantly higher than that in MC-PF in both groups. However, TPSB2 and TPSD1 expression levels in the MC-RF did not differ between the groups. Tryptase genes were highly expressed in the synovium of overweight HOA patients. Further investigation to reveal the role of tryptase in the relationship between increasing BMI and HOA pathology is required.
Between the number and the word: quantitative methods in business history revisited

This article extends our earlier analysis (2010) to gauge, first, to what extent quantitative methods have been used in recent business history research and, second, the impact that quantitative methods may have had on the citations of business history articles. We used data from the two premier journals in the field (Business History and Business History Review) of the last 20 years. We found that the quantitative content has not increased in relative terms recently in these journals, yet it has in absolute terms. However, at the same time more sophisticated statistical methods have been used more frequently also in business historical research. Contrary to our earlier results, quantitative methods no longer have an easily discernible impact on citation patterns, yet the explicit use of theories seems to have increased the appeal of such scholarship. The unclear impact on citations may be due, at least in part, to a time lag in interdisciplinary knowledge networks. We also argue that the growing impact of economics and economic history, global and comparative history, and digital big data methods will necessitate more use of quantitative methods in the future, with citation impacts becoming observable only in the coming decades.
Occupations and Preoccupations of the Australian Library Profession: An Analysis of Job Advertisements and Professional Literature

ABSTRACT The aim of this paper was to find out how knowledge and skills in demand by libraries compare with librarians’ preoccupations and aspirations. Two sets of data were analysed using content analysis. A) 972 criteria in 127 Australian library-related job advertisements (from 2021) were coded against ALIA’s Foundation knowledge for entry-level library and information professionals. B) 465 articles published in INCITE (an Australian professional LIS magazine) from 2018 to 2020 were mapped against the framework afforded by the IFLA Trend Report 2019 Update. From the ten domains in ALIA’s foundation knowledge, behavioural skills were the most sought domain in the job advertisements (84.3% of advertisements), followed by those of leadership and management (58.3%), digital technologies (49.6%), and literacies and learning (22%). Professionalism (5.5%) and research (14.2%) were the least sought domains. Of the three key trends identified by IFLA, the top preoccupation in the professional literature was found to be ‘dealing with uncertainty’ (60.2% of articles). This is the first study to analyse both job advertisements and professional literature and map them against expected professional competencies and the sector’s emerging trends.
Antenna-coupled Photoemission from Single Quantum Emitters

Optical antennas are analogs of their radiowave and microwave counterparts, and can be defined as devices that serve to efficiently convert free-propagating optical radiation to localized energy, and vice-versa. Colloidal metal nanoparticles with their strong plasmonic optical response offer a convenient realization of optical antennas. Such nanoparticle antennas serve to spatially enhance and localize fields, and modify the excitation rate and the radiative decay rate when placed close to single emitters (molecules, quantum dots, etc.). In addition, they can also cause undesirable losses, leading to an increase in the non-radiative decay rates of these emitters. This interplay of rates can lead to a strong modification of the emission characteristics over the intrinsic behavior. We study photoemission from single emitters coupled to antennas of different geometries made from colloidal metal nanoparticles. We demonstrate enhancements of fluorescence from single quantum emitters by a factor 10 to 100, with the highest enhancements resulting for molecules with very low intrinsic quantum yields. Such enhancements afford an improvement in resolution for fluorescence imaging down to λ/40. We also investigate changes to fluorescence blinking of a colloidal quantum dots (QD) coupled to an antenna, as a function of antenna-QD distance. We find that power-law blinking is preserved unaltered even as the antenna drastically modifies the excitonic decay rate in the QD, and reduces the blinking probability.
The Determinants of Cryptocurrency Returns

This study examines the determinants of cryptocurrency returns, namely Trading Volume, Price Volatility, and Market Capitalization. This study uses Bitcoin, Ethereum, Tether, USD Coin, and BNB, which are the Top 5 largest Cryptocurrency Market Capitalizations in 2022. The testing method used in this study is a panel data regression analysis. The results of this study prove that Trading Volume and Price Volatility have a significant and positive effect on Cryptocurrency Returns. In contrast, Market Capitalization does not substantially impact Cryptocurrency Returns. If investors want to earn high returns, then it is advisable to choose cryptocurrencies with high trading volume and high price volatility. But keep in mind, with high price volatility can also mean a greater risk of the coin.

Modeling and Control of a Snake-like Serial-link Structure

HICKS, GREGORY PHILIP. Modeling and Control of a Snake-like Serial-link Structure (Under the direction of Kazufumi Ito). The topic considered is the modeling and control of a snake-like serial-link structure. The system is assumed to have torque controls about the joints, is considered to lie in an isotropic plane, and is assumed to interact with this plane in a manner which adheres to some suitable friction laws. Such a structure is hyper-redundant, making the robotic realization thereof potentially robust with regards to mechanical failure and highly suited for obstacle avoidance tasks and terrain adaptability. It is for these reasons that the structure is studied. Lagrangian mechanics is used to develop a mathematical model for the system. The resulting dynamics possess symmetries which allow them to be placed in a reduced form. Using this form in conjunction with a technique known as feedback linearization, one finds that the dynamics are driven by a three state system describing the evolution of generalized momenta with respect to the device’s internal shape progression. The problem is to determine whether or not there is a shape trajectory that can elicit bulk structure movement. In order to determine the appropriate shape for this task a two-pronged approach is taken. One approach is to make a shape selection based on the principle mechanism of undulatory locomotion. The other approach is to set up a variational problem to determine an optimal locomotive shape.
IDENTICAL ANTIMICROBIAL EFFECT OF CEFTRIAXONE AND CEFOTAXIME AMONG DIFFERENT BACTERIAL ISOLATES

Background: This study aimed to screen the antimicrobial-resistant profile of these 3rd generation cephalosporins and to identify their similarity and interchangeability. Method: This cross-sectional study, was conducted in all the government hospitals across the Gaza Strip, Palestine. The study started in November 2017 and continued till December 2022. All clinical samples such as wound swabs (pus), urine, sputum, blood, cerebrospinal fluid (CSF), stool, and others in which ceftriaxone and cefotaxime were examined at the same time were collected from hospitalized patients and outpatient clinic attendants. After the identification of the bacterial isolates, a standard disc diffusion technique for drug susceptibility tests was performed. This study was reviewed and approved by The Palestinian Helsinki Committee. Results: In the current study, 24,120 isolates in which ceftriaxone and cefotaxime were examined at the same time were studied. The predominant organisms isolated were, Escherichia coli 9,720 (40.3%), Klebsiella spp. 5,497 (22.8%), Pseudomonas spp. 2,630 (10.9%), and Staphylococcus aureus 1941 (8.0%). Bacterial isolates showed 57.1% and 57.8% resistance against ceftriaxone and cefotaxime, respectively. In this study, 22,404 (92.9%) bacterial isolates were with identical susceptibility test results to ceftriaxone and cefotaxime. The highest match of susceptibility was seen in Acinetobacter spp. 97.3% (770/791), Klebsiella spp. 95.3% (5,241/5,491), and Escherichia coli 94.9% (9,220/9,720). In Staphylococcus aureus it was 90.6% (1,758/1,941). Conclusion: Ceftriaxone and cefotaxime can be interchangeable in most Enterobacteriaceae bacterial species. Ongoing surveillance of different bacterial antimicrobial resistance and multidrug resistance is strongly recommended together with the consideration of implementing antibiotics stewardship programs in all hospitals.
Development of Articulate Storyline 3-Based Digital Teaching Materials on the Subject of Atomic Structure and Periodic Elements System for SMA/MA Students in Class X

The articulate storyline 3 application is a multimedia authoring tool used to create interactive learning media with content from a combination of text, images, graphics, sound, animation, and video that is usable on various devices such as laptops, tablets, and smartphones. Teaching materials developed based on articulate storyline 3 can help independent learning. The development model used as a reference in this study is the Borg and Gall model which consists of 5 stages: preliminary studies, design and development, design validation and revision, product trial, and final product dissemination. The results of the assessment of material and media experts on the level of validity of digital teaching materials have a very valid category with a percentage of validity throughout the whole at 87.95% and 93.3%, respectively. The student response to the digital teaching material during the trial was very positive, with an average overall percentage of 95.71% in small-group trials and 95% in large-group trials. Thus, digital teaching materials based on Articulate Storyline 3 on the subject matter of atomic structure and periodic systems of these elements are suitable for use in chemistry learning activities as a source of independent learning and learning media.
Priority altitude PVTOL aircraft control via immersion and invariance

ABSTRACT In this work, the immersion and invariance (I&I) control technique is used in order to design a new controller that stabilises the PVTOL (planar vertical take-off and landing) aircraft system. The controller gives priority to the control of the aircraft's altitude before controlling the lateral displacement, fact from which interesting features as less thrust effort and less aggressive manoeuvres for roll moment are gained. The fundamental idea for the development of the proposed controller is based on the selection of the target dynamic system in accordance with the nature of the translational motion system to then stabilise the off-manifold dynamics by using the rotational motion system. It is proved that the proposed control scheme is globally asymptotically stable. Simulation results validate our proposal.
The computational brain

From the Publisher: How do groups of neurons interact to enable the organism to see, decide, and move appropriately? What are the principles whereby networks of neurons represent and compute? These are the central questions probed by The Computational Brain. Churchland and Sejnowski address the foundational ideas of the emerging field of computational neuroscience, examine a diverse range of neural network models, and consider future directions of the field. The Computational Brain is the first unified and broadly accessible book to bring together computational concepts and behavioral data within a neurobiological framework. Computer models constrained by neurobiological data can help reveal how networks of neurons subserve perception and behavior--how their physical interactions can yield global results in perception and behavior, and how their physical properties are used to code information and compute solutions. The Computational Brain focuses mainly on three domains: visual perception, learning and memory, and sensorimotor integration. Examples of recent computer models in these domains are discussed in detail, highlighting strengths and weaknesses, and extracting principles applicable to other domains. Churchland and Sejnowski show how both abstract models and neurobiologically realistic models can have useful roles in computational neuroscience, and they predict the coevolution of models and experiments at many levels of organization, from the neuron to the system. The Computational Brain addresses a broad audience: neuroscientists, computer scientists, cognitive scientists, and philosophers. It is written for both the expert and novice. A basic overview of neuroscience and computational theory is provided, followed by a study of some of the most recent and sophisticated modeling work in the context of relevant neurobiological research. Technical terms are clearly explained in the text, and definitions are provided in an extensive glossary. The appendix contains a precis of
Maternal Diet May Modulate Breast Milk Microbiota—A Case Study in a Group of Colombian Women

There is increasing evidence that the diet and nutritional status of women during pregnancy and lactation can modulate the microbiota of their milk and, therefore, the microbiota of the infant. An observational, descriptive, and cross-sectional study was carried out in a group of lactating women. Dietary intake during gestation and the first trimester of lactation was evaluated, and the microbiota was analyzed by 16S ribosomal RNA (rRNA) sequencing using the Illumina platform. Globally, Streptococcus spp. (32%), Staphylococcus spp. (17.3%), Corynebacterium spp. (5.1%) and Veillonella spp. (3.1%) were the predominant bacterial genera. The consumption of simple carbohydrates in gestation (rho = 0.55, p ≤ 0.01) and lactation (rho = 0.50, p ≤ 0.01) were positively correlated with Enterobacter spp. In lactation, a negative correlation was observed between the intake of simple carbohydrates and the genus Bifidobacterium spp. (rho = −0.51 p ≤ 0.01); furthermore, a positive correlation was identified between the intake of folic acid and Akkermansia spp. (rho = 0.47, p ≤ 0.01). Amplicon sequence variants (ASVs) associated with the delivery mode, employment relationship, the baby’s gender, birth weight, the Body Mass Index (BMI) of the breastfeeding woman, and gestational weight gain were recovered as covariates in a linear mixed model. The results of this research showed that the maternal nutritional status and diet of women during gestation and lactation could modulate the microbiota of breast milk.
Progress in the Treatment of Lumbar Disc Herniation

In recent years, the number of patients with lumbar disc herniation (LDH) has gradually increased and their age has gradually become younger. It seriously affects the daily life and work of patients and increases their sense of pain. At home and abroad, the treatment methods for LDH are mainly divided into two categories, Western medicine treatment and traditional Chinese medicine treatment. Western medicine treatment mainly focuses on surgery and drug treatment, and minimally invasive surgery during surgery is gradually becoming a trend, but it may cause complications, which is not conducive to the postoperative recovery of patients. Western medicine treatment can alleviate pain symptoms to a certain extent, but long-term use leads to poor patient compliance. Traditional Chinese medicine mainly includes acupuncture and moxibustion, bone setting, etc. In addition to treatment, sports and psychological therapies also play an important role in the intervention and treatment of LDH. Each method has its own advantages, and different treatment methods should be given to different patients in order to achieve the best clinical treatment effect, in order to provide better research direction for clinical scholars.
Quantification of coumarins, furocoumarins and polymethoxyflavones in hydroalcoholic fragrances by supercritical fluid chromatography‐tandem mass spectrometry

ABSTRACT Citrus essential oils, thanks to their pleasant aroma, are certainly the most used ingredients in the formulation of hydroalcoholic fragrances. The non-volatile fraction of Citrus essential oil is composed for 10–20% of coumarins, furocoumarins and polymethoxyflavones. It is well known that furocoumarins induce photosensitization and have potential carcinogenic and mutagenic effects. It follows that furocoumarins levels in cosmetics product are constantly monitored by opinions and regulations issued by the International Fragrance Association. The aim of this research article was to quantify coumarins, furocoumarins and polymethoxyflavones in thirty commercial hydroalcoholic fragrances using supercritical fluid chromatography in combination with triple quadrupole mass spectrometry technique (SFC-QqQ-MS). According to author’s knowledge, this is the first report on the determination of oxygen heterocyclic compounds in hydroalcoholic fragrances by means of SFC-QqQ-MS technique.
Microscopic and Molecular Prevalence of Cryptosporidium spp. in Lambs in Siirt, Turkey

C RYPTOSPORIDIOSIS is a zoonotic disease that occurs acutely or chronically in young or immune-compromised animals and humans, caused by Cryptosporidium species. Cryptosporidium is recognized as one of the major enteropathogens associated with neonatal diarrhea in ruminants. The aim of this study is to determine the prevalence of Cryptosporidium spp. in lambs in Siirt province using microscopic and molecular methods. The fecal materials of the study collected from 194 randomly selected lambs of different sexes, up to 4 weeks of age, in various farms. As a result of microscopic examination, Cryptosporidium spp. oocysts were found in 54 (27.84%) of 194 samples, while specific bands were obtained in 63 (32.47%) samples as a result of Nested PCR analysis. A statistically significant relationship was found between lambs with and without diarrhea ( P <0.001) while no statistically significant relationship was found between age groups, gender, and locations ( P >0.05). In conclusion, the data obtained from this study revealed that Cryptosporidium infection is present in Siirt province, and Cryptosporidium spp. should be considered as one of the agents in the etiology of neonatal diarrhea in lambs.
Cholesteric gratings induced by electric field in mixtures of liquid crystal and novel chiral ionic liquid

ABSTRACT Formation of gratings upon alternating electric field in compositions of highly birefringent liquid crystal (LC) with novel chiral ionic liquid (CIL) enclosed in 10-µm-thick cells is studied. The compatibility of two organic components of the mixture is investigated. The grating is formed in 1–5% CIL mixtures and causes significant changes of the transmission of polarised light through the cells. Transmission of polarised λ = 633 nm light through the 5% CIL sample is studied with respect to frequency (1 Hz–3 MHz) and amplitude (up to 10 V) of alternating voltage and the results are used for sketch a voltage–frequency phase diagram. Two possible ways of formation of the gratings with perpendicular orientation to that formed from initial state are presented. Two twisting axes in the molecular alignments of the cholesteric LC gratings with perpendicular directions are proposed. Optical switch based on four different states of LC including two gratings with perpendicular directions is proposed. Moreover, behaviour of the rotation of a grating induced by AC field in hybrid planar-homeotropic cell is studied in two frequency regimes and rotation by more than 90° upon change of the AC field amplitude is observed.

A Computational Study of the Fourth Painleve Equation and a Discussion of Adams Predictor-Corrector Methods

How far the stability domain of a numerical method for approx imating solutions to differential equations extends along the imaginary axis indicates how useful the method is for approximating solutions to wave equations; this maximu m extent is termed the imaginary stability boundary, also known as the stability ordinate. I has previously been shown that exactly half of Adams-Bashforth, Adams-Moulton, and stagg ered Adams-Bashforth methods have nonzero stability ordinates. In this paper, we cons ider two categories of Adams predictor-corrector methods and prove that they follow a si milar pattern. In particular, if p is the order of the method, AB p-AM p methods have nonzero stability ordinate only for p = 1,2, 5,6, 9,10, . , and AB(p−1)-AMp methods have nonzero stability ordinates only for p = 3,4, 7,8, 11,12, .
