Sentiment Classification of Tweets with Explicit Word Negations and Emoji Using Deep Learning

The widespread use of social media platforms such as Twitter, Instagram, Facebook, and LinkedIn have had a huge impact on daily human interactions and decision-making. Owing to Twitter's widespread acceptance, users can express their opinions/sentiments on nearly any issue, ranging from public opinion, a product/service, to even a specific group of people. Sharing these opinions/sentiments results in a massive production of user content known as tweets, which can be assessed to generate new knowledge. Corporate insights, government policy formation, decision-making, and brand identity monitoring all benefit from analyzing the opinions/sentiments expressed in these tweets. Even though several techniques have been created to analyze user sentiments from tweets, social media engagements include negation words and emoji elements that, if not properly pre-processed, would result in misclassification. The majority of available pre-processing techniques rely on clean data and machine learning algorithms to annotate sentiment in unlabeled texts. In this study, we propose a text pre-processing approach that takes into consideration negation words and emoji characteristics in text data by translating these features into single contextual words in tweets to minimize context loss. The proposed preprocessor was evaluated on benchmark Twitter datasets using four deep learning algorithms: Long Short-Term Memory (LSTM), Recurrent Neural Network (RNN), and Artificial Neural Network (ANN). The results showed that LSTM performed better than the approaches already discussed in the literature, with an accuracy of 96.36%, 88.41%, and 95.39%. The findings also suggest that pre-processing information like emoji and explicit word negations aids in the preservation of sentimental information. This appears to be the first study to classify sentiments in tweets while accounting for both explicit word negation conversion and emoji translation.
Outcomes of Ceramic-on-Ceramic Total Hip Arthroplasties After Ten Years at Cork University Hospital Ireland

Objectives: We conducted a retrospective observational study to investigate the patients’ reported outcomes and survival of ceramic-on-ceramic total hip arthroplasty. Patients and Methods: 238 patients underwent ceramic on ceramic hip arthroplasties between January, 2010 and October 2012. Out of these, 205 patients (86.1%) had uncemented fixations and 33 patients (13.9%) had cemented fixations with THA using a CoC femoral head and liner. For each patient, WOMAC and SF-12 scores were measured at six weeks, six months, two years, and five years. Radiological follow up to 10 years. The patients who received revision surgery were identified in the database. Results: The mean preoperative WOMAC and SF-12 scores were 39.83±12.29 and 30.07±2.18, respectively. At 5 years, the mean WOMAC score had improved from 39.83 ± 12.29 to 90.40 ± 5.30 (p < 0.01), Wilcoxon signed-rank test; the mean SF-12 score had improved from 30.07 ± 2.18 to 34.40 ± 2.22 (p < 0.01, Wilcoxon signed-rank test). Four patients (1.68%) got revision within 10 years postoperatively. Conclusion: The CoC THA showed statistically significant clinical improvement in WOMAC score and functional score of SF-12 after 5 years follow-up with satisfactory survival after 10 years.
Curcumin–Triterpene Type Hybrid as Effective Sonosensitizers for Sonodynamic Therapy in Oral Squamous Cell Carcinoma

Sonodynamic therapy (SDT) is a non-invasive therapeutic modality in cancer treatment that combines low-intensity ultrasound (US) and sonosensitizers. Tumor cells are destroyed through the synergistic effects of ultrasound and a chemical sonosensitizer. This study focused on the synthesis and in vitro evaluation of the sonodynamic effect of natural curcumin, triterpene oleanolic acid, and their semi-synthetic derivatives on tongue cancer SCC-25 and hypopharyngeal FaDu cell lines. The combination of the tested compounds with sonication showed a synergistic increase in cytotoxicity. In the group of oleanolic acid derivatives, oleanoyl hydrogen succinate (6) showed the strongest cytotoxic effect both in the SCC-25 and FaDu cell lines. Comparing curcumin (4) and its pyrazole derivative (5), curcumin showed a better cytotoxic effect on SCC-25 cells, while curcumin pyrazole was more potent on FaDu cells. The highest sonotherapeutic activity, compared to its individual components, was demonstrated by a structural linker mode hybrid containing both curcumin pyrazole-oleanoyl hydrogen succinate units within one complex molecule (7). This study can be beneficial in the context of new perspectives in the search for effective sonosensitizers among derivatives of natural organic compounds.
Inclusion/Exclusion Meets Measure and Conquer Exact Algorithms for Counting Dominating Sets

In this paper, two central techniques from the field of ex- ponential time algorithms are combined for the first time: inclusion/ex- clusion and branching with measure and conquer analysis. In this way, we have obtained an algorithm that, for each κ ,c ounts the number of dominating sets of size κ in O(1.5048 n ) time. This algorithm improves the previously fastest algorithm that counts the number of minimum dominating sets. The algorithm is even slightly faster than the previous fastest algorithm for minimum dominating set, thus improving this result while computing much more information. When restricted to c-dense graphs, circle graphs, 4-chordal graphs or weakly chordal graphs, our combination of branching with inclusion/ex- clusion leads to significantly faster counting and decision algorithms than the previously fastest algorithms for dominating set. All results can be extended to counting (minimum) weight dominating sets when the size of the set of possible weight sums is polynomially bounded.
Refrigeration Control Algorithm for Managing Supermarket’s Overall Peak Power Demand

Demand-side management is an integral part of smart grids, which stabilizes and optimizes the power supply grid. For the consumer side, the demand management represents a way to reduce the energy costs. In this brief, a controllability of refrigeration system’s power demand is validated in order to manage the supermarket’s overall peak power demand. The applied control approach performs short-term adjustments of the refrigeration power demand, while taking into account the temperature limitations of air and stored items. Separate temperature constraints increase the demand shifting capabilities, and an additional dynamic reference adjustment approach provides a mean to significantly increase the control performance needed for overall peak demand minimization. Simulation model of the commercial refrigeration system and real overall power demand measurements are used as a use case. The results show high usability and applicability of the proposed approach to manage even the worst case overall peak power demands solely with refrigeration power demand adjustments.

In this paper, We proposed the efficient method of cleaning impulse noise using mean shift segmentation. This method do its job for the pixel which is identified as impulse noise using mean shift segmentation instead of all pixel of image by the existing method. we found that the quality of image is improved by measuring the sum of square error in result image and impulse noise is cleaned efficiently by doing experiment.
Self-Evolving Chebyshev Radial Basis Function Neural Complementary Sliding Mode Control

A novel intelligent complementary sliding mode control (ICSMC) method is proposed for nonlinear systems with unknown uncertainties in this paper. A self-evolving Chebyshev radial basis function neural network (RBFNN) (SECRBFNN) with self-learning parameters and structure is proposed and combined with complementary sliding mode control (CSMC). CSMC not only has the advantages of the strong robustness of traditional SMC but also has certain advantages in reducing chattering and control accuracy. The SECRBFNN, which combines the advantages of the Chebyshev network (CN) and an RBFNN, is used to estimate unknown uncertainties in nonlinear systems. Meanwhile, a node self-evolution mechanism is proposed to avoid redundancy in the number of neurons. Eventually, the detailed simulation results demonstrate the feasibility and superiority of the proposed method.
High-power laser diodes with high polarization purity

Fiber-coupled laser diode modules employ power scaling of single emitters for fiber laser pumping. To this end, techniques such as geometrical, spectral and polarization beam combining (PBC) are used. For PBC, linear polarization with high degree of purity is important, as any non-perfectly polarized light leads to losses and heating. Furthermore, PBC is typically performed in a collimated portion of the beams, which also cancels the angular dependence of the PBC element, e.g., beam-splitter. However, we discovered that single emitters have variable degrees of polarization, which depends both on the operating current and far-field divergence. We present data to show angle-resolved polarization measurements that correlate with the ignition of high-order modes in the slow-axis emission of the emitter. We demonstrate that the ultimate laser brightness includes not only the standard parameters such as power, emitting area and beam divergence, but also the degree of polarization (DoP), which is a strong function of the latter. Improved slow-axis divergence, therefore, contributes not only to high brightness but also high beam combining efficiency through polarization.
Amelioration of Ultrasonic Transducer to Study CuO Doped Thin Films

Ultrasonic pulse echo technique was used to study cupric oxide (CuO) thin films. CuO thin films were prepared using sol gel technique. They were doped with Lithium (Li) (1%, 2% and 4%). Thin films’ thickness (d) and band gap energy (Eg) were measured. In addition, elastic moduli (longitudinal (L), shear (G), bulk (K) and Young’s (E)) and Poisson’s ratio (v) were determined to estimate the microstructure properties of the prepared films. The study ameliorated the used transducers to overcome their dead zone and beam scattering; wedges were developed. The results showed the effectiveness of these wedges. They enhanced transducers’ sensitivity by changing the dead zone, beam diameter, beam directivity and waves’ transmission. Also, the study noted that Li doping caused the improvement of CuO thin films to be more useful in solar cell fabrication. Li-CuO thin films had narrower band gap. Thus, they acquired a high quantum yield for the excited carriers; also they gained more efficiency to absorb solar light.
Achromatic on-chip focusing of graphene plasmons for spatial inversions of broadband digital optical signals

Abstract. On-chip focusing of plasmons in graded-index lenses is important for imaging, lithography, signal processing, and optical interconnects at the deep subwavelength nanoscale. However, owing to the inherent strong wavelength dispersion of plasmonic materials, the on-chip focusing of plasmons suffers from severe chromatic aberrations. With the well-established planar dielectric grating, a graded-index waveguide array lens (GIWAL) is proposed to support the excitation and propagation of acoustic graphene plasmon polaritons (AGPPs) and to achieve the achromatic on-chip focusing of the AGPPs with a focus as small as about 2% of the operating wavelength in the frequency band from 10 to 20 THz, benefiting from the wavelength-independent index profile of the GIWAL. An analytical theory is provided to understand the on-chip focusing of the AGPPs and other beam evolution behaviors, such as self-focusing, self-collimation, and pendulum effects of Gaussian beams as well as spatial inversions of digital optical signals. Furthermore, the possibility of the GIWAL to invert spatially broadband digital optical signals is demonstrated, indicating the potential value of the GIWAL in broadband digital communication and signal processing.
Back to the Basics: Usefulness of Naturally Aged Mouse Models and Immunohistochemical and Quantitative Morphologic Methods in Studying Mechanisms of Lung Aging and Associated Diseases

Aging-related molecular and cellular alterations in the lung contribute to an increased susceptibility of the elderly to devastating diseases. Although the study of the aging process in the lung may benefit from the use of genetically modified mouse models and omics techniques, these approaches are still not available to most researchers and produce complex results. In this article, we review works that used naturally aged mouse models, together with immunohistochemistry (IHC) and quantitative morphologic (QM) methods in the study of the mechanisms of the aging process in the lung and its most commonly associated disorders: cancer, chronic obstructive pulmonary disease (COPD), and infectious diseases. The advantage of using naturally aged mice is that they present characteristics similar to those observed in human aging. The advantage of using IHC and QM methods lies in their simplicity, economic accessibility, and easy interpretation, in addition to the fact that they provide extremely important information. The study of the aging process in the lung and its associated diseases could allow the design of appropriate therapeutic strategies, which is extremely important considering that life expectancy and the number of elderly people continue to increase considerably worldwide.
Planar premixed-flame/end-wall interaction: the jump conditions across the thin flame

Within the context of time-dependent interaction of a planar premixed laminar flame with a cold parallel end wall, the jump conditions for the first (spatial) derivatives of the dependent variables across the thin flame are obtained through the solution of the nonlinear diffusive-reactive boundary-value problem that describes the structure of the flame zone. Recently developed numerical techniques are employed to yield solutions of this boundary-value problem.
Bean-Counting Research and the Mismanagement of Knowledge Production in Business Schools

Notorious cases of corporate misconduct often revolve around the misapplication of pay to performance. Yet many business schools have too easily given themselves up to these kinds of high-powered incentives in the management of research. This practice is contrary to the very management knowledge taught in business school classrooms and it can wreak havoc with business schools’ mission of knowledge production. The reduction of managing research to a bean-counting performance evaluation, that is, keeping count of discrete units of research outputs as A-class journal hits and citation counts, has arguably tilted the scales in favor of form and against content. This undermines both the quality of knowledge produced and the autonomy that academics need to create knowledge. Much as combat sports, football or soccer, and democratic societies prevent certain traits and actions from conferring an unfair advantage, academics need to reclaim the principle of a level playing field to prevent practices inimical to the academic enterprise.
Electron collisions—experiment, theory, and applications

Electron collisions with atoms, ions, and molecules have represented an important area of ‘applied quantum mechanics’ for more than a century. This Topical Review is the write-up of the Allis Prize Lecture given by the author at the 2016 meeting of the Division of Atomic, Molecular, and Optical Physics of the American Physical Society and the 2017 Gaseous Electronics Conference. In light of the enormous size of the field, the examples presented were selected in order to tell the story of how experimental and theoretical/numerical methods have developed over time, how fruitful collaborations between data producers (experimentalists and theorists) and data users have led to significant progress, and how the results of these studies, which were often designed for fundamental research in order to push both experiment and theory to new frontiers, continue to be highly sought after for modeling applications in a variety of fields. The impact of electron collision studies on other fields, such as photoinduced processes and quantum information, is also discussed.
Soft x-ray imaging telescope (Xtend) onboard X-ray Astronomy Recovery Mission (XARM)

X-ray Astronomy Recovery Mission (XARM) scheduled to be launched in early 2020’s carries two soft X-ray telescopes. One is Resolve consisting of a soft X-ray mirror and a micro calorimeter array, and the other is Soft X-ray Imaging Telescope (Xtend), a combination of an X-ray mirror assembly (XMA) and an X-ray CCD camera (SXI). Xtend covers a field of view (FOV) of 38′ × 38′ , much larger than that of Resolve (3′ × 3 ′ ) with moderate energy resolution in the energy band from 0.4 keV to 13 keV, which is similar to that of Resolve (from 0.3 keV to 12 keV). Simultaneous observations of both telescopes provide complimentary data of X-ray sources in their FOV. In particular, monitoring X-ray sources outside the Resolve FOV but inside the Xtend FOV is important to enhance the reliability of super high resolution spectra obtained with Resolve. Xtend is also expected to be one of the best instruments for low surface brightness X-ray emissions with its low non X-ray background level, which is comparable to that of Suzaku XIS. The design of Xtend is almost identical to those of Soft X-ray Telescope (SXT) and Soft X-ray Imager (SXI) both on board the Hitomi satellite. However, several mandatory updates are included. Updates for the CCD chips are verified with experiment using test CCD chips before finalizing the design of the flight model CCD. Fabrication of the foils for XMA has started, and flight model production of the SXI is almost ready.
A Systematic Review of the Effect of Vericiguat on Patients with Heart Failure

Despite recent advances in heart failure (HF) therapy, the risk of cardiovascular (CV) mortality, morbidity, and HF hospitalization (HFH) are major challenges in HF treatment. We aimed to review the potential of vericiguat as a treatment option for HF. A systematic literature review was performed using the PubMed database and ClinicalTrials.gov. Four randomized controlled trials were identified, which study the safety and efficacy of vericiguat in HF patients. Vericiguat activates soluble guanylate cyclase (sGC) by binding to the beta-subunit, bypassing the requirement for NO-induced activation. The nitric oxide (NO)–sGC–cyclic guanosine monophosphate (cGMP) pathway plays an essential role in cardiovascular (CV) regulation and the protection of healthy cardiac function but is impaired in HF. Vericiguat reduced the risk of CV death and HFH in HF patients with reduced ejection fraction (HFrEF) but showed no therapeutic effect on HF with preserved ejection fraction (HFpEF). The trials demonstrated a favorable safety profile with most common adverse events such as hypotension, syncope, and anemia. Therefore, vericiguat is recommended for patients with HFrEF and a minimum systolic blood pressure of 100 mmHg. Treatment with vericiguat is considered when the individual patient experiences decompensation despite being on guideline-recommended medication, e.g., angiotensin-converting inhibitor/AT1 receptor antagonist, beta-adrenoceptor antagonist, spironolactone, and sodium-glucose transporter 2 inhibitors. Furthermore, larger studies are required to investigate any potential effect of vericiguat in HFpEF patients. Despite the limitations, vericiguat can be recommended for patients with HFrEF, where standard-of-care is insufficient, and the disease worsens.
POST-DISCIPLINE COMMUNICATION ON THE STRAIGHT WAY

The development of communication studies is currently driven by the information technology paradigm, making the discipline of communication a very sexy study, leaving other disciplines behind. Old communication studies traditions such as media effects, framing studies, agenda- setting, as well as various media impact studies, public relations, broadcasting, journalism and the like are grouped as traditional communication studies. Meanwhile, the development of the world of communication driven by social media and internet-based technology has made the world of communication very sexy and has attracted the attention of various disciplines by starting to connect disciplines outside of communication with communication disciplines, so that communication is referred to as post-communication. discipline. This study examines thinking by classifying the development of thinking in traditional communication disciplines and post- discipline communication. Collecting data using interviews and conducting library research. The conclusion of this study is that the communication discipline in today's world is distinguished between traditional and post-discipline disciplines. In developed countries, these two disciplines become an equally important conversation, while in new developing countries, communication of traditional disciplines becomes dominant. In Indonesia, communication stakeholders must maintain these two communication disciplines, this is what is meant by straight way communication.
