FeelPen: A Haptic Stylus Displaying Multimodal Texture Feels on Touchscreens

The ever-emerging mobile market induced a blooming interest in stylus-based interactions. Most state-of-the-art styluses either provide no haptic feedback or only deliver one type of sensation, such as vibration or skin stretch. Improving these devices with display abilities of a palette of tactile feels can pave the way for rendering realistic surface sensations, resulting in more natural virtual experiences. However, integrating necessary actuators and sensors while keeping the compact form factor of a stylus for comfortable user interactions challenges their design. This situation also limits the scientific knowledge of relevant parameters for rendering compelling artificial textures for stylus-based interactions. To address these challenges, we developed FeelPen, a haptic stylus that can display multimodal texture properties (compliance, roughness, friction, and temperature) on touchscreens. We validated the texture rendering capability of our design by conducting system identification and psychophysical experiments. The experimental results confirmed that FeelPen could render a variety of modalities with wide parameter ranges necessary to create perceptually salient texture feels, making it a one-of-a-kind stylus. Our unique design and experimental results pave the way for new perspectives with stylus-based interactions on future touchscreens.

An Economic Analysis of the Factors Affecting the Organization and Cultivation of the Wheat Crop in Iraq Using Logistic Regression

The research aimed to analyze the factors affecting the organization and cultivation of the wheat crop in Iraq by using one of the appropriate econometric analysis methods for this type of research, which is the logistic regression, through which it is possible to know the results of the application of agricultural legislation and the variables affecting compliance with those legislation as well as knowing the role of agricultural legislation in supporting policy steps agriculture in Iraq. The results showed that among the model variables, there was a set of factors described as the most influential on the farmer’s decision to adhere to the government agricultural plan, including the variable delay in receiving marketing amounts and the variable providing loans, as well as the variable value of the returns achieved in the presence of government support in favour of adhering to the agricultural plan. As for the farmers’ decision to market their crops to the state, it was found that the most influential variables were the commitment to the agricultural plan, the state’s selling price variable, and the total area. The research concluded that paying attention to the aspect of financing and providing agricultural loans to farmers will lead to farmers getting rid of the financial restrictions imposed on them by the private sector, and thus increasing the likelihood of their commitment to implementing agricultural legislation. Also, the continued provision of government support, especially in the aspect of output, will lead to an improvement in the level of farm income for farmers, which makes them needless to search for other means to obtain income and thus comply with the government legislation drawn up. The research recommended the need to work on improving the reality of agricultural crop production by providing government support for the use of modern technologies to increase production rates per unit area and achieve greater returns for farmers. As well as the need for a strict supervisory body working to ensure that farmers do not violate the government legislation imposed in order to regulate production and develop the agricultural sector.
Mycosynthesis of Silver Nanoparticles and Evaluation as Insecticidal Against the Sunn Pest Eurygaster testudinaria in Vitro

Fungi are used to synthesize metal nanoparticles such as silver nanoparticles (AgNPs) because of their specifications as lower toxicity and eco-friendly behavior. Extracellular mycosynthesis of Lecanicillium lecanii silver nanoparticles (AgNPs) was performed, which was done by a redox reaction, where the filtrate crude of L. lecanii acts as a reducing and stabilizing agent for the formation of nanoparticles. The green synthesized AgNPs were evaluated as insecticidal against the adults of sunn pest Eurygaster testudinaria. The AgNPs were characterized by ultraviolet-visible (UV–vis) spectroscopy, Fourier transform infrared (FITR) spectroscopy, X-ray diffraction (XRD), and Field Emission Scanning Electron Microscopy (FESEM). The UV–Vis spectroscopy showed a characteristic absorption peak at 418.5 nm due to surface plasma resonance. FESEM analysis showed that synthesized AgNPs were semi-spherical with an average size of 39.45 nm. The AgNPs showed strong activity in mortality of adults of E. testudinaria under conditions during different periods of time to recorded 100% at concentration 100 ppm compared with 0.00% in control treatment after 10 days from treatment.
What Does the Milky Way Look Like?

In spite of much work, the overall spiral structure morphology of the Milky Way remains somewhat uncertain. In the last two decades, accurate distance measurements have provided us with an opportunity to solve this issue. Using the precise locations of very young objects, for the first time, we propose that our galaxy has a multiple-arm morphology that consists of two-arm symmetry (the Perseus and Norma Arms) in the inner parts and that extends to the outer parts, where there are several long, irregular arms (the Centaurus, Sagittarius, Carina, Outer, and Local Arms).
STUDIES OF SURFACE DIFFUSION AND DISSI- PATIVE PARTICLE DYNAMICS

In the first part of this thesis, we study diffusion of atoms on solid surfaces. To this end, we carry out Monte Carlo simulations for a lattice-gas model of O/W(110), first on clean surfaces and then on surfaces containing small concentrations of quenched (immobile) impurities. In both cases, we examine how thermodynamic non-equilibrium affects tracer diffusion and collective diffusion of atoms on a surface. We find that non-equilibrium effects can play an important role when there are strong interactions in the system. These effects persist even when there are only slight deviations from equilibrium. We also find that even minute impurity concentrations can lead to major changes in the diffusion coefficients. The combined effect is not, however, additive. Indeed, we find that the non-equilibrium effects are most pronounced on clean surfaces, while on surfaces covered by impurities the role of non-equilibrium conditions is weaker. This is essentially due to the similarity between disorder as induced either by the non-equilibrium condition or by the presence of impurities on the surface. In the second part of the thesis, we consider methodological aspects of the dissipative particle dynamics (DPD) technique. First, we address the question: “How to integrate the equations of motion in DPD simulations? ” We test and analyze several novel DPD integration schemes on an equal footing through DPD simulations of different model systems. By monitoring a number of physical observables including temperature, radial distribution function, radius of gyration for polymers, and tracer diffusion, we find that the methods by Lowe and Shardlow give the best overall performance and are superior also to the integrators tested in previous studies. Second, we study the dynamics of polymer melts. In standard DPD, as well as in other coarse-grained soft potential models, there is a problem that polymers can penetrate through themselves. This is a clear artifact, and has direct consequences on polymer dynamics. To correct this problem, we tune the conservative forces within the polymer chain so strong that chains cannot cut through each other. Indeed, if a certain geometric criterion is met, it is impossible for polymer chains to cross. Through DPD simulations, we show that our approach is able to reproduce the Rouse-like dynamics for short chains and reptational dynamics for longer chains. The results are in good agreement with polymer theories and experiments.
Unrecognized diversity, genetic structuring, and phylogeography of the genus Triplophysa (Cypriniformes: Nemacheilidae) sheds light on two opposite colonization routes during Quaternary glaciation that occurred in the Qilian Mountains

Abstract In recent years, the influence of historical geological and climatic events on the evolution of flora and fauna in the Tibetan Plateau has been a hot research topic. The Qilian Mountain region is one of the most important sources of biodiversity on the Qinghai‐Tibet Plateau. Many species existed in the region during the Pleistocene glacial oscillation, and the complex geographical environment provided suitable conditions for the survival of local species. The shrinkage, expansion, and transfer of the distribution range and population size of species have significant effects on genetic diversity and intraspecific differentiation. To reveal the effects of geological uplift and climate oscillation on the evolution of fish populations in the Qilian Mountains, we investigated the genetic structure, phylogenetic relationship, and phylogeographical characteristics of genus Triplophysa species in the Qilian Mountains using the mitochondrial DNA gene (COI), three nuclear genes (RAG1, sRH, and Myh6) and 11 pairs of nuclear microsatellite markers. We collected 11 species of genus Triplophysa living in the Qilian Mountains, among which Triplophysa hsutschouensis and Triplophysa papillosolabiata are widely distributed in the rivers on the northern slope of the Qilian Mountains. There was a high degree of lineage differentiation among species, and the genetic diversity of endemic species was low. The different geographical groups of T. papillosolabiata presented some allogeneic adaptation and differentiation, which was closely related to the changes in the river system. Except for the population expansion event of T. hsutschouensis during the last glacial period of the Qinghai‐Tibet Plateau (0.025 MYA), the population sizes of other plateau loach species remained stable without significant population expansion. Starting from the east and west sides of the Qilian Mountains, T. hsutschouensis, and T. papillosolabiata showed two species colonization routes in opposite directions. The geological events of the uplift of the Qinghai‐Tibet Plateau and the climatic oscillation of the Quaternary glaciation had a great influence on the genetic structure of the plateau loach in the Qilian Mountains, which promoted the genetic differentiation of the plateau loach and formed some unique new species. The results of this study have important guiding significance for fish habitat protection in the Qilian Mountains.
Novel Variant Identified in the Enhancer Region of Host Transcription Factor, BRN3A, is a Significant Risk Factor for HPV-Induced Uterine Cervix Cancer

Among the HPV-mediated cervical cancers, cellular factor BRN3A has gained considerable attention due to its role in promoting an anti-apoptotic cellular environment and in facilitating epitheliotropic transformations of the host. The majority of previous studies looked at BRN3A's molecular characteristics; however, the possibility of genetic variations in BRN3A's auto-regulatory region in relation to cervical cancer risk has been underestimated until now. In a retrospective study in the Eastern UP population, India, we detected genetic variations in the cis-regulatory proximal enhancer region located around 5.6 kb upstream of transcription start site of BRN3A. Our analysis of PCR and DNA sequencing confirmed this novel SNP (BRN3A g.60163379A>G) within the auto-regulatory region of BRN3A. As compared to control subjects, cancer cases exhibited a 1.32-fold higher allele frequency (χ2 = 6.315, p = 0.012). In homozygous (GG) but not in heterozygous conditions, odds ratio (OR) analysis suggests a significant association of cancer risk with the SNP (OR = 2.60, p ≤ 0.004). We further confirmed using the functional analysis that this SNP increased the luciferase gene activity in HPV-positive cervical cancer SiHa cells that were exposed to progesterone. As a result of the association of polymorphisms in a non-coding region of an oncogene with increased cancer risks, we are suggesting that this genetic variation in non-coding region can be used in prediction, diagnosis, or predicting the progression of the disease.
Testing the predictive value of functional traits in diverse ant communities

Abstract Associating morphological features with ecological traits is essential for understanding the connection between organisms and their roles in the environment. If applied successfully, functional trait approaches link form and function in an organism. However, functional trait data not associated with natural history information provide an incomplete picture of an organism's role in the ecosystem. Using data on the relative trophic position of 592 ant (Formicidae) samples comprising 393 species from 11 subfamilies and 19 widely distributed communities, we tested the extent to which commonly used functional proxies (i.e., morphometric traits) predict diet/trophic position as estimated from stable isotopes (δ15N). We chose ants as a group due to their ubiquity and abundance, as well as the wealth of available data on species traits and trophic levels. We measured 12 traits that have previously been identified as functionally significant, and corrected trait values for size and evolutionary history by using phylogenetically corrected trait residuals. Estimated trophic positions varied from 0.9 to 4.8 or roughly 4 trophic levels. Morphological data spanned nearly the entire size range seen in ants from the smallest (e.g., Strumigenys mitis total length 1.1 mm) to the largest species (e.g., Dinoponera australis total length 28.3 mm). We found overall body size, relative eye position, and scape length to be informative for predicting diet/trophic position in these communities, albeit with relatively weak predictive values. Specifically, trophic position was negatively correlated with body size and positively correlated with sensory traits (higher eye position and scape length). Our results suggest that functional trait‐based approaches can be informative but should be used with caution unless clear links between form and function have been established.
Treatment of large gastric trichobezoar in children: Two case reports and literature review

Rationale: Gastric trichobezoars are a rare form of bezoar formed from swallowed human hair as well as hair from dolls or animals, blankets, and carpets. They usually develop in young women who are emotionally disturbed, depressed, or mentally retarded, with trichotillomania and trichophagia. They can lead to abdominal pain, gastric ulceration, bleeding, obstruction, and perforation. Patient concerns: A 13-year-old girl was admitted to our institution with complaints of nausea, vomiting, and epigastric pain for 2 days. She underwent laparoscopic removal of a large gastric trichobezoar at our institution 5 years ago. A 12-year-old girl presented at our institution due to epigastric pain, dizziness, and melena for 2 days. Diagnosis: They were diagnosed with gastric trichobezoar by abdominal computed tomography scan and upper gastrointestinal endoscopy. Interventions: Large gastric trichobezoars were removed via a mini-laparotomy. Outcomes: They recovered well postoperatively without complication. Lessons: Although the recurrence of gastric trichobezoar after surgery is rare, few recurrent cases were reported in the literature. Therefore, psychiatric consultation and regular follow-up after treatment should be considered in the children and their parents to prevent the recurrence of gastric trichobezoar.
