Triangular formation control with mixed distance and bearing measurements under limited field of view constraints

This article addresses the problem of triangular formation control for a three‐agent group with different measuring capabilities: agent 1 can measure local bearings but with limited field of view (FOV), and agents 2 and 3 can only obtain distance measurements. For agent 1, an orientation controller is first designed to steer its heading to the expected direction. Furthermore, a type of switching control law utilizing pure bearing measurements is proposed to reach the desired angle with respect to the other two agents. Concurrently, it is guaranteed that the flip ambiguity of the formation can be excluded. For agents 2 and 3, the extended distance‐based control algorithm is proposed by invoking the so‐called signed area strategy to determine their actuation. With this control scheme, it is proven that the triangular formation is stabilized globally even in the presence of FOV constraints. The effectiveness is validated through numerical simulations and physical experiments on three nano quadrotors.

This paper studies the pathwise asymptotic stability of the zero solution of scalar stochastic differential equation of Ito type. Specifically, we provide conditions for solutions to converge to zero at given non-exponential rates. The results completely classify the rates of decay of many parameterised families of stochastic differential equations.
Neurotensin receptors in GtoPdb v.2023.1

Neurotensin receptors (nomenclature as recommended by NC-IUPHAR [39]) are activated by the endogenous tridecapeptide neurotensin (pGlu-Leu-Tyr-Glu-Asn-Lys-Pro-Arg-Arg-Pro-Tyr-Ile-Leu) derived from a precursor (NTS, 30990), which also generates neuromedin N, an agonist at the NTS2 receptor. [3H]neurotensin (human, mouse, rat) and [125I]neurotensin (human, mouse, rat) may be used to label NTS1 and NTS2 receptors at 0.1-0.3 and 3-5 nM concentrations respectively.

Algorithms in Invariant Theory (Texts and Monographs in Symbolic Computation)

J. Kung and G. -C. Rota, in their 1984 paper, write: Like the Arabian phoenix rising out of its ashes, the theory of invariants, pronounced dead at the turn of the century, is once again at the forefront of mathematics. The book of Sturmfels is both an easy-to-read textbook for invariant theory and a challenging research monograph that introduces a new approach to the algorithmic side of invariant theory. The Groebner bases method is the main tool by which the central problems in invariant theory become amenable to algorithmic solutions. Students will find the book an easy introduction to this classical and new area of mathematics. Researchers in mathematics, symbolic computation, and computer science will get access to a wealth of research ideas, hints for applications, outlines and details of algorithms, worked out examples, and research problems.
Twelve Weeks of High-Intensity Interval Training Alters Adipose Tissue Gene Expression but Not Oxylipin Levels in People with Non-Alcoholic Fatty Liver Disease

Lifestyle modifications, including increased physical activity and exercise, are recommended for non-alcoholic fatty liver disease (NAFLD). Inflamed adipose tissue (AT) contributes to the progression and development of NAFLD and oxylipins such as hydroxyeicosatetraenoic acids (HETE), hydroxydocosahexanenoic acids (HDHA), prostaglandins (PEG2), and isoprostanoids (IsoP), which all may play a role in AT homeostasis and inflammation. To investigate the role of exercise without weight loss on AT and plasma oxylipin concentrations in NAFLD subjects, we conducted a 12-week randomized controlled exercise intervention. Plasma samples from 39 subjects and abdominal subcutaneous AT biopsy samples from 19 subjects were collected both at the beginning and the end of the exercise intervention. In the AT of women, a significant reduction of gene expression of hemoglobin subunits (HBB, HBA1, HBA2) was observed within the intervention group during the 12-week intervention. Their expression levels were negatively associated with VO2max and maxW. In addition, pathways involved in adipocyte morphology alterations significantly increased, whereas pathways in fat metabolism, branched-chain amino acids degradation, and oxidative phosphorylation were suppressed in the intervention group (p < 0.05). Compared to the control group, in the intervention group, the ribosome pathway was activated, but lysosome, oxidative phosphorylation, and pathways of AT modification were suppressed (p < 0.05). Most of the oxylipins (HETE, HDHA, PEG2, and IsoP) in plasma did not change during the intervention compared to the control group. 15-F2t-IsoP significantly increased in the intervention group compared to the control group (p = 0.014). However, this oxylipin could not be detected in all samples. Exercise intervention without weight loss may influence the AT morphology and fat metabolism at the gene expression level in female NAFLD subjects.
NanoFN10: A High-Contrast Turn-On Fluorescence Nanoprobe for Multiphoton Singlet Oxygen Imaging

An “off-on” fluorescent nanoprobe for near-infrared multiphoton imaging of singlet oxygen has been developed. The nanoprobe comprises a naphthoxazole fluorescent unit and a singlet-oxygen-sensitive furan derivative attached to the surface of mesoporous silica nanoparticles. In solution, the fluorescence of the nanoprobe increases upon reaction with singlet oxygen both under one- and multiphoton excitation, with fluorescence enhancements up to 180-fold. The nanoprobe can be readily internalized by macrophage cells and is capable of imaging intracellular singlet oxygen under multiphoton excitation.
Literature review of the Internet Provider Service Quality based on Sentiment Analysis

As of February 2020, Covid-19 has spread in Indonesia. Since then, people's behavior started to change. The spread of the virus required people to do a physical distance and stay at home. The offline activity started to be shifted into online activities. Working from home, learning from home, and buying from home are the new lifestyle. In this situation, people depend more on a wifi connection, and it could be seen as an opportunity for the internet service provider company. In fact, providing the best service quality to customers is still a challenge faced by the internet service provider as there are still a lot of complaints from customers. Therefore, companies need to measure their service quality performance based on their customer's testimonials. One of the ways to see customers' opinions regarding the service quality is to do text mining, more specifically sentiment analysis from Twitter because people tend to give more honest testimonials in their tweets. The service quality research with text mining to do the analysis of people's sentiment related to the company's service quality is potentially utilized for this study due to its being considered more efficient than using a questionnaire. A literature exploration from previous research was conducted to identify whether using text mining and sentiment analysis to measure the service quality provided by ISP company is possible to do. Six papers were then reviewed. Result shows that using text mining and sentiment analysis to identify the service quality provided by companies is possible to do. Out of six papers that were reviewed, only two of them using ISP as the main object. Service quality literature which use text mining and sentiment analysis to define the quality of service provided in ISP industry is still rarely done by researcher. Meanwhile, public’s need for internet service is growing. This should be seen as an opportunity for researcher to do more research regarding the service quality of ISP companies so they could improve.
Tutorial: Defects in semiconductors—Combining experiment and theory

Point defects affect or even completely determine physical and chemical properties of semiconductors. Characterization of point defects based on experimental techniques alone is often inconclusive. In such cases, the combination of experiment and theory is crucial to gain understanding of the system studied. In this tutorial, we explain how and when such comparison provides new understanding of the defect physics. More specifically, we focus on processes that can be analyzed or understood in terms of configuration coordinate diagrams of defects in their different charge states. These processes include light absorption, luminescence, and nonradiative capture of charge carriers. Recent theoretical developments to describe these processes are reviewed.
A Dynamic Product Evaluation Model Based on Online Customer Reviews from the Perspective of the Elaboration Likelihood Model

Plenty of online customer reviews (OCRs) provide consumers with an abundant source of word-of-mouth (WOM). It makes potential customers evaluate alternative products or services more conveniently. Thus, relative studies have been arising. Considering that existing research is almost deployed from the perspective of reviewers, the study proposes an evaluation model based on the OCRs from the view of potential customers. In the model, the OCRs in text form are translated into probabilistic linguistic term sets from the perspective of the cognitive process model, namely, the elaboration likelihood model, for further evaluation. Meanwhile, the influence of the OCRs’ published time is also taken into consideration, and then, the model is transformed into a dynamic evaluation model. In general, we propose a dynamic product evaluation model to simulate the cognitive process of the potential consumers disposing of OCRs. In addition, an evaluation of 6 hotels in Chengdu, Sichuan Province, is developed based on the proposed dynamic product evaluation model, and some discussions, as well as conclusions, are also carried out.
Mode-locking at very high repetition rates more than terahertz in passively mode-locked distributed-Bragg-reflector laser diodes

We propose a technique for achieving mode-locking at very high repetition rates more than terahertz with high output power using a distributed-Bragg-reflector (DBR) laser, including an intracavity saturable absorber. This method is based on harmonic passive mode-locking at high gain levels and the selectivity of harmonic numbers related to the spectrum-filtering property of the intracavity Bragg reflector. Transform-limited pulses at repetition rates from 500 GHz to 1.54 THz were generated with an output power exceeding 15 mW. We studied stability of harmonic pulses by using conventional self-consistent mode-locking equations. We also discuss the effect of the spectrum-filtering properties of the intracavity Bragg reflector to the characteristics of mode-locked pulses.
An FPGA Based Crypto Processor through Triangular Modulo Arithmetic Technique (TMAT)

In this paper a block cipher based new cryptosystem has been proposed, where the encryption is done through Triangular Modulo Arithmetic Technique (TMAT), which consists of three phases. The original message is considered as a stream of bits. In Phase 1, bit stream is divided into a number of equal size blocks. Then the Triangular algorithm is performed on odd blocks, where even blocks are remain unchanged and together form a bit stream. In Phase 2, MAT is performed on that bit stream, which is divided into a number of blocks, each containing n bits, n is 2 k, , k is 1, 2, 3 and so on. Then modulo addition is performed between first and second block and the content of the second block is replaced by the result, where the first block is remain unchanged. This is continuing till the last block is changed and also for block size n is 2, 4, 8, and so on. In case of modulo addition the carry out of the MSB is discarded. In Phase 3, the Triangular algorithm is performed on even blocks but odd blocks are remain unchanged and together form output stream. In case of decryption, reverse algorithm is used, where modulo subtraction technique is performed instead of performing modulo arithmetic technique.
A price leadership method for solving the inspector's non-constant-sum game

Abstract : An inspector's game is a non-constant sum 2person game in which one player has promised to perform a certain duty a5d the other player is allowed to occasionally inspect and verify that the duty has indeed been performed. A solution to a variant of such a game is given in this paper, based on the assumption that the inspector can announce his mixed strategy in advance, if he so wishes, whereas the other player, who has already given his promise, cannot threat by explicitly saying that he will not keep his word.

Pulsed field magnetization of a rectangular Y–Ba–Cu–O bulk, single grain superconductor assembly

The practical magnetization of arrays of multiple single grain, bulk high temperature superconductors is essential for practical applications, such as trapped flux rotating machines, magnetic resonance imaging and nuclear magnetic resonance. We report a systematic investigation of the pulsed field magnetization (PFM) of a bulk assembly consisting of two rectangular Y–Ba–Cu–O bulk single grains, in close proximity, at various temperatures. The measurements of the dynamic variation of the magnetic flux density, supported by numerical analysis, reveal that the induced screening currents during the rise of a pulsed field may greatly enhance the flux density in the region of the junction leading to uneven flux penetration and to an increased likelihood of flux jumps in this region. Such coupling between field and current promotes magnetic flux penetration and improves the peak trapped field from 3.01 T for a bulk single grain to 3.11 T for the bulk assembly at 30 K, improving the magnetization efficiency from 80% to 90%. The peak trapped field was further enhanced to 3.39 T and 3.31 T for the single bulk single grain and the bulk assembly, respectively, by employing a two-step multi-pulse PFM process.
Determination of Minerals in Soft and Hard Cheese Varieties by ICP-OES: A Comparison of Digestion Methods

For sample preparation prior to mineral analysis, microwave digestion (~2 h) is quicker and requires lower acid volume as compared to dry (6–8 h) and wet digestion (4–5 h). However, microwave digestion had not yet been compared systematically with dry and wet digestion for different cheese matrices. In this work, the three digestion methods were compared for measuring major (Ca, K, Mg, Na and P) and trace minerals (Cu, Fe, Mn and Zn) in cheese samples using inductively coupled plasma optical emission spectrometry (ICP-OES). The study involved nine different cheese samples with moisture content varying from 32 to 81% and a standard reference material (skim milk powder). For the standard reference material, the relative standard deviation was lowest for microwave digestion (0.2–3.7%) followed by dry (0.2–6.7%) and wet digestion (0.4–7.6%). Overall, for major minerals in cheese, strong correlation was observed between the microwave and the dry and wet digestion methods (R2 = 0.971–0.999), and Bland–Altman plots showed best method agreement (lowest bias), indicating the comparability of all three digestion methods. A lower correlation coefficient, higher limits of agreement and higher bias of minor minerals indicate possibilities of measurement error.
Mental Health in Coronary Heart Disease (CHD) Patients: Findings from the UK Household Longitudinal Study (UKHLS)

Objectives: Mental health conditions in patients with coronary heart disease (CHD) are closely related to clinical outcomes. Thus, this study’s goal is to investigate how CHD affects general and specific aspects of mental health. Methods: We analyzed data from Wave 10 Understanding Society: the UK Household Longitudinal Study (UKHLS), which were collected between 2018 and 2019. After removing people who had missing data, there were 450 participants who indicated that they have CHD, and 6138 age- and sex-matched healthy participants indicated that they were not clinically diagnosed with CHD. Results: The main findings were that participants with CHD had more mental health problems, as shown by the GHQ-12 summary score (t (449) = 6.00, p < 0.001, 95% C.I. [0.20, 0.40], Cohen’s d = 0.30), social dysfunction and anhedonia, (t (449) = 5.79, p < 0.001, 95% C.I. [0.20, 0.40], Cohen’s d = 0.30), depression and anxiety (t (449) = 5.04, p < 0.001, 95% C.I. [0.15, 0.33], Cohen’s d = 0.24), and loss of confidence (t (449) = 4.46, p < 0.001, 95% C.I. [0.11, 0.30], Cohen’s d = 0.21). Conclusion: This study implies that GHQ-12 is a valid assessment of mental health problems in CHD patients, and there is a need to consider how different aspects of mental health are affected by CHD rather than solely focusing on depression or anxiety problems alone in patients with CHD.
A toddler infected with mucormycosis – reporting the youngest case of mucormycosis in post COVID phase

Mucormycosis is a rare disease but has gained more attention than before because of coronavirus disease 2019 (COVID-19) pandemic. Mucormycosis is fungal infection caused by fungi Mucoraceae. [1] It mostly affects immunocompromised adults and children and causes mortality of about 50%. We are reporting the management of rhino-orbital mucormycosis in a 3-year-old girl, which till date must be the youngest reported case of this fatal disease in India.
Estimation of particulate zinc using MERIS data of the Pearl River Estuary

Marine heavy metals in the particulate phase are considered to be undetectable from remote sensing since their minor spectral signal is masked by marine optical constitutes. However, over 80% of heavy metals adsorb to and complex with the suspended sediment and the quantity of adsorbed heavy metals strongly depends on suspended sediment load and size. Thus, the suspended sediment load and size could be useful information to estimate heavy metal levels through remote-sensing techniques. We investigate the potential to derive heavy metal concentration, using zinc as an example. Eight cruises in the Pearl River Estuary were carried out to measure zinc concentrations in the particulate phase (C zn) and remote-sensing reflectance (R rs) data from 2009 to 2010. The relationship of R rs ratio in the near infrared bands and the scattering spectral slope (which indicates particle size distribution (PSD)) is first proposed. According to a previously established suspended sediment algorithm for the study area and the newly proposed relationship of remote-sensing reflectance and suspended sediment size, a piecewise algorithm is developed to retrieve C zn. The accuracies of the algorithm developed here (correlation coefficient (r) = 0.88, mean relative error (MRE) = 24.7% and root mean square error (RMSE) = 5.51) are higher than those algorithms only considering suspended sediment load (r = 0.79, MRE = 35.3% and RMSE = 8.93) or size (r = 0.78, MRE = 30.0% and RMSE = 7.19). The algorithm is applied to Medium Resolution Imaging Spectrometer (MERIS) full resolution data to obtain C zn distribution in the Pearl River Estuary. The C zn from image is mainly in the range from 10 to 63 μg l−1, which is consistent with the in situ data ranges (5.67–86.62 μg l−1).
Disrupting the Organizational Frontlines

As an introduction to a Journal of Service Research special issue in 2017, Singh et al. advanced the concept of studying the organizational frontline as a noun, signaling a conceptual shift from the paradigm of using “frontline” as a qualifying adjective to modify a phenomenon of interest (i.e., frontline employee, frontline tensions, or frontline knowledge). This special issue builds upon this concept by presenting papers that examine the frontline itself. Specifically, the focus of this special issue is to highlight changes that are impacting the organizational frontline, driven by both man and nature, that have sparked disruptions in frontline routine. A functioning society is based upon personal routine and interpersonal assumptions for guiding our behaviors (Collins 1981). That is, we all rely upon social norms to help guide us. What happens, though, when such assumptions and routines are disrupted? What triggers such disruptions, and what forms might such disruptions take? The purpose of this introduction to the special issue is to examine such key elements of disruption in relation to changes developing at the organizational frontline. This examination of disruption will then be linked to each of the articles found in the special issue. In order to accomplish this, we first begin with a discussion of what is meant by disruption. We then offer a definition of disruption in relation to the organizational frontline. Following this, we discuss the sources, severity, and speed elements associated with disruption at the organizational frontline. This allows for the categorization of disruption, which then facilitates the placement of research focused on disruption and changes in the organizational frontline. We conclude by looking forward to research needed across these domains.
Providing security using CAPTCHA: CAPTCHA as a graphical password

Various security primitives uses hard mathematical problems. Use of hard AI problems for security is emerging and exciting new pattern, but has not yet been explored. In our project, we present a new security primitive based on hard AI problems, this system is named as Captcha as graphical passwords (CaRP). CaRP is Captcha as well as graphical password scheme. CaRP symbolize a number of security problems together, such as online guessing attacks, relay attacks, and shoulder-surfing attacks. Generally, a CaRP password can be found only probabilistically by automatic online guessing attacks even if the password is in the search set CaRP also offers well approach to address the well-known image hotspot problem in popular graphical password systems, like PassPoints, that generally leads to choices of weak password.
