Event-related microblog retrieval in Turkish

: Microblogs, such as tweets, are short messages in which users are able to share any opinion and information. Microblogs are mostly related to real-life events reported in news articles. Finding event-related microblogs is important to analyze online social networks and understand public opinion on events. However, finding such microblogs is a challenging task due to the dynamic nature of microblogs and their limited length. In this study, assuming that news articles are given as queries and microblogs as documents, we find event-related microblogs in Turkish. In order to represent news articles and microblogs, we examine encoding methods, namely traditional bag-of-words and word embeddings provided by BERT and FastText pretrained language models based on deep learning. We find the distance between the encoded news article and microblog to measure text similarity or relatedness between them. We then rank microblogs according to their relatedness to the input query. The experimental results show that (i) BERT-based model outperforms other encoding methods in Turkish, though bag-of-words with Dice similarity has a challenging performance in short text; (ii) news title is successful to represent event as query, and (iii) preprocessing Turkish microblogs has positive impact in bag-of-words and also FastText embeddings, while BERT embeddings are robust to noise in Turkish.
A cephalometric study of sella turcica size and morphology among young Iraqi normal population in comparison to patients with maxillary malposed canine

Sella turcica - bony depression located in sphenoid bone that houses and protects the pituitary gland. Calcification of the interclinoid ligament of the sella turcica, or sella turcica bridging, has been associated with severe craniofacial deviations and with dental anomalies. The permanent canines are the foundation of an esthetic smile and functional occlusion. It's the most commonly ectopically erupting permanent teeth after maxillary first molars, so an attempt to guide impacted canines into functional occlusion should be made . The aims of this study were to establish normative reference standards of Sella Turcica size in Iraqi sample that could assist in a more objective evaluation and detection of pathological conditions, secondly to compare the size measurements of Sella Turcica between normal subjects and patients with buccally and palatally maxillary malposed canine, and to evaluate the prevalence of Sella Turcica bridging in young subjects with malposed canine using lateral cephalometric imaging. Material and method: Lateral cephalometric images for 40 subjects(18 male and 22 female), aged between 13 and 25 years, with displaced or impacted canines were reviewed and compared with a control group (60 male and 60 female). The size of Sella turcica (length, depth and diameter) was measured and the bridging was evaluated. Results: The results show no significant differences in linear dimensions between genders, and the prevalence of Sella Turcica bridging was higher in subjects with malposed canine (70%) when compared with control group. All linear measurements of Sella Turcica were within standard range. The prevalence of Sella Turcica bridge in subjects with displaced or impacted canine is increased. Conclusion: Early appearance of Sella Turcica bridge during development should alert clinicians to possible tooth anomalies in later life.
The Pictures we Like are our Image: Multiple Instance Regression for Mapping Aesthetic Preferences into Personality Traits

Flickr allows its users to tag the pictures they like as “favorite”. As a result, many users of the popular photosharing platform produce galleries of favorite pictures that account, at least in principle, for their aesthetic preferences. This article proposes new approaches, based on Computational Aesthetics and Multiple Instance Regression, capable of inferring the personality traits of Flickr users from the galleries above. In particular, the approaches map low-level features extracted from the pictures into numerical scores corresponding to the Big-Five Traits, both self-assessed and attributed. The experiments were performed over 60,000 pictures tagged as favorite by 300 users (the PsychoFlickr Corpus). The results show that it is possible to predict beyond chance both self-assessed and attributed traits. In line with the state-of-the-art of personality computing, these latter are predicted with higher effectiveness (correlation up to 0.68 between actual and predicted traits).
UNBOUNDED EIGENVALUE PROBLEMS IN THE GENERALIZED FORM

Unbounded eigenvalue problems in the generalized form are reformulated, implicitly leading to bounded standard eigenvalue problems. By performing implicit linear fractional transformations, the way this can be done is doubly parametrized by the resolvent set. The reformulated problems are then studied in terms of appropriate quotients which can be used to approximate eigenvalues. Based on the location of these quotients, a case for the notion of symmetric eigenvalue problem is made by inspecting an unbounded quadratic form involving two operators. A notion of self-adjointness then arises through reality of the spectrum. The structure proposed extends the classical self-adjointness of a single operator in a natural way. Orthogonality of eigenvectors takes place together with variational characterizations of eigenvalues. In approximating eigenvalues, trial functions are generated by iterating with a certain type of linear fractional transformation, potentially giving rise to cubic convergence in the self-adjoint case proposed.
Effect of High Frequency Current Injection on Optical Feedback Noise in Semiconductor Lasers Operating in Multimode

The performance of semiconductor injection lasers is limited by optical feedback noise. The laser intensity noise is greatly increased even by small amount of optical feedback. Although superposition of high-frequency current on the injection current is popularly used to solve the problem, proper modulation frequency and depth must be chosen empirically. In this paper, we numerically analyze this problem based on a set of multimode rate equations, modified to include OFB (optical feedback) and HFI (high frequency current). We concentrate only on low frequency type noise where intensity noise is maximum in the lower frequency region. The results show that the feedback noise was reduced when HFI released coupling effects and thereby suppressed mode hopping. The feedback noise was still remained high when the modulation frequency was coincided with a rational number of the round trip time period of optical feedback. A simple formula together with a tree is newly reported from experimental and numerical data to find the rational numbers at which the feedback noise remains high for a particular external cavity length. Dependency of the rational numbers on external cavity lengths is also reported in this paper.
The Influence of Exchange Rate Fluctuations on US Outward FDI

This paper makes a contribution to the literature on the effects of uncertainty of exchange rates over the foreign direct investment (FDI) decisions of US firms. The purpose being to find out what influence fluctuations of the value of a currency and the volatility of the exchange rates has on the level of US outward FDI. The focus is on the value of the home country currency in relation to host country currency and the level of exchange rate volatility; this is done by adopting the model by Pantelidis & Kyrkilis (2003, 2005), to this one additional independent variable is included, namely exchange rate volatility which was not used in their model. Based on the multiple correlation analysis, the findings revels a significant relation between the change in currency value (ER) and change in US outward FDI. Moreover the relation between volatility (ERVL) and change in US outward FDI is also significant.
Association between Negative Life Events on Mental Health and College Student Adjustment: A Mediated Moderating Effect

Objective: To explore the association between negative life events and college student adjustment and to explore the mediating and moderating effects of social support and grade level in the relationship between the two. Methods. The research was conducted with 1717 college students using the Adolescent Self-Rating Life Events Checklist (ASLEC), China College Student Adjustment Scale (CCSAS), and the Social Support Rating Scale (SSRS). Results. (1) Negative life events were significantly negative in correlation with adjustment and social support (r = −0.373, −0.174, Ps < 0.001), while social support was significantly positive in correlation with adjustment (r = 0.359, P < 0.001). (2) The main effects of negative life events, social support, and grade on adjustment were significant (effect = −0.190, P < 0.001, 95% CI [−0.288∼−0.092]; effect = 0.307, P < 0.001, 95% CI [0.265∼0.348]; effect = 0.163, P < 0.001, 95% CI [0.126∼0.200]). (3) In the relationship between negative life events and adjustment, social support played a mediating role (effect = −0.054, 95% CI [−0.071∼−0.037]) and grade level played a moderating role (effect = −0.049, P=0.009, 95% CI [−0.085∼−0.012]). Conclusion. Negative life events, social support, and grade level affected college student adjustment, and social support networks for college students should be actively constructed and targeted education should be conducted according to different grade levels, which can promote college student adjustment.
Evaluation of the Effect of PDCA in Hospital Health Management

PDCA plays a very important role in the hygienic management of hospital operating rooms. Before the PDCA management from February 2018 to February 2019, routine hygiene management in the operating room was adopted; after the PDCA management from February 2018 to February 2019, PDCA cycle management was adopted. 500 surgical patients were randomly selected from both groups. We compare the quality control checklist scores of hand hygiene management, environmental hygiene management, medical waste management, and disinfection and isolation management in the routine group and the PDCA group. We also compared the detection rate of pathogenic bacteria in surgical incisions of the routine group and the PDCA group and the infection rate of various surgical incisions, air samples, surface samples, disinfectants, and sterilization rates of sterile items. The PDCA group's hand hygiene management score, environmental hygiene management score, medical waste management score, and disinfection and isolation management score were higher than those in the conventional group (P < 0.05). The detection rate of pathogenic bacteria in the PDCA group, the infection rate of type I, type II, and type III incisions, and the total infection rate of surgical incisions were lower than those in the conventional group, and the difference was statistically significant (P < 0.05). The qualified rate of air samples and surface samples in the PDCA group was higher than that in the conventional group (P < 0.05), and the difference in the qualified rate of disinfectants and sterile items between the two groups was not statistically significant (P > 0.05). The hygiene management of the operating room adopts PDCA sustainable improvement management measures to effectively increase the qualification rate of disinfection and sterilization, reduce the detection rate of pathogenic bacteria and infection rate of surgical incisions, and strengthen the management quality of hand hygiene, environmental hygiene, medical waste, and disinfection and isolation.
The use of the wavelet approximation signal as a tool for the diagnosis of rotor bar failures

The aim of this paper is to present a way for the diagnosis of rotor bar breakages in induction machines. The method is focused on the study of an approximation signal resulting from the wavelet decomposition of the startup stator current. The existence of a left sideband harmonic is used as an evidence of the rotor failure for most of the diagnosis methods based on the analysis of the stator current. Thus, a detailed description of the evolution of the left sideband harmonic during the startup transient is given in this paper; for this purpose, some physical considerations are done and a numerical model is used. In this sense, it is shown that the approximation signal of a particular level, obtained from the discrete wavelet transform (DWT) of the stator startup current, practically reproduces the time evolution of the left sideband harmonic during the startup. The diagnosis method proposed consist on checking if the selected approximation signal matches with the shape of the left sideband harmonic evolution described before. The method is checked through simulation and laboratory tests, being proved that it can be a useful tool for the rotor bar breakage diagnosis.
Korean /l/-flapping in an /i/-/i/ context

In this study, we aim to describe kinematic characteristics of Korean /l/-flapping in two speech rates (fast vs. comfortable). Production data was collected from seven native speakers of Seoul Korean (four females and three males) using electromagnetic midsagittal articulometry (EMMA), which provided two dimensional data on the x-y plane. We examined kinematic properties of the vertical/horizontal tongue tip gesture, the vertical/horizontal (rear) tongue body gesture, and the jaw gesture in an /i/-/i/ context. Gestural landmarks of the vertical tongue tip gesture are directly measured. This serves as the actual anchoring time points to which relevant measures of other trajectories referred. The study focuses on velocity profiles, closing/opening spatiotemporal properties, constriction duration, and constriction minima were analyzed. The results are summarized as follows. First, gradiently distributed spatiotemporal values of the vertical tongue tip gesture were on a continuum. This shows more of a reduction in fast speech rate, but no single instance of categorical reduction (deletion). Second, Korean /l/-flapping predominantly exhibited a backward sliding tongue tip movement, in 83% of production, which is apparently distinguished from forward sliding movement in English. Lastly, there was an indication of vocalic reduction in fast rate, truncating spatial displacement of the jaw and the tongue body, although we did not observe positional variations with speech rate. The present study shows that Korean /l/-flapping is characterized by mixed articulatory properties with respect to flapping sounds of other languages such as English and Xiangxiang Chinese. Korean /l/ flapping demonstrates a language-universal property, such as the gradient nature of its flapping sounds that is compatible with other languages. On the other hand, Korean /l/-flapping also shows a language-particular property, particularly distinguished from English, in that a backward gliding movement occurs during the tongue tip closing movement. Although, there was no vocalic reduction in V2 observed in terms of jaw and tongue body height, spatial displacement of these articulators still suggests truncation in fast speech rate.
Antiviral Abidol is Associated with the Reduction of In-Hospital Mortality in COVID-19 Patients

Abstract Objective: Coronavirus disease 2019 (COVID-19) is a global public health crisis. There are no specific antiviral agents for the treatment of SARS-CoV-2. Information regarding the effect of Abidol on in-hospital mortality is scarce. The present study aimed to evaluate the treatment effect of Abidol for patients with COVID-19 before and after propensity score matching (PSM). Methods: This retrospective cohort study analyzed 1019 patients with confirmed COVID-19 in China from December 22, 2019 to March 13, 2020. Patients were divided to Abidol (200 mg, tid, 5–7 days, n = 788, 77.3%) and No-Abidol (n = 231, 22.7%) groups. The primary outcome was the mortality during hospitalization. Results: Among 1019 COVID-19 patients, the age was (60.4 ± 14.5) years. Abidol-treated patients, compared with No-Abidol-treated patients, had a shorter duration from onset of symptoms to admission, less frequent renal dysfunction, lower white blood cell counts (lymphocytes <0.8) and erythrocyte sending rate, lower interleukin-6, higher platelet counts and plasma IgG and oxygen saturation, and less frequent myocardial injury. The mortality during hospitalization before PSM was 17.9% in Abidol group and 34.6% in No-Abidol (hazard ratio (HR) = 2.610, 95% confident interval (CI): 1.980–3.440), all seen in severe and critical patients. After PSM, the in-hospital death was 13.6% in Abidol and 28.6% in No-Abidol group (HR = 2.728, 95% CI: 1.598–4.659). Conclusions: Abidol-treatment results in less in-hospital death for severe and critical patients with COVID-19. Further randomized study is warranted to confirm the findings from this study.
Evaluation of 3D-CEUS in the Recurrence of Liver Cancer after Radiofrequency Ablation

Background Radiofrequency ablation (RFA) has the similar curative effects to surgery, but RFA will lead to higher postoperative local recurrence rate. 3D-CEUS is a minimally invasive examination method, which is used to analyze the sensitivity to postoperative recurrence in this study. Methods The clinical data of 60 patients with liver cancer admitted to our hospital (February 2018-February 2020) were retrospectively analyzed. All patients were treated with RFA and were followed up with 3D-CEUS, MRI, and enhanced CT examination after surgery. The ROC curve was used to analyze the differences of different examination methods in judging postoperative recurrence. Results For the 60 patients, 52 patients (86.7%) had a single lesion and 8 patients (13.3%) had multiple lesions, with a total of 72 lesions. After RFA, 56 lesions (77.8%) were completely inactivated and 16 lesions (22.2%) remained. Totally inactivated lesions were detected as follows: 51 (91.1%) by 3D-CEUS, 42 (75.0%) by MRI, and 50 (89.3%) by enhanced CT. During a 2-year follow-up, a total of 26 recurrent lesions were detected, 24 (92.3%) by 3D-CEUS, 12 (46.2%) by MRI, and 25 (96.2%) by enhanced CT, indicating that the sensitivity of 3D-CEUS and enhanced CT was obviously higher than that of MRI (P < 0.001), without conspicuous difference between sensitivity of 3D-CEUS and enhanced CT (P > 0.05). Conclusion As a new imaging examination method based on artificial intelligence, 3D-CEUS has a high sensitivity in patients with liver cancer who underwent RFA, which can effectively judge the recurrence after surgery and should be widely used in practice.
Physical Fitness and Chemotherapy Tolerance in Patients with Early-Stage Breast Cancer

ABSTRACT Introduction An optimal relative dose intensity (RDI) of adjuvant chemotherapy is associated with better survival in patients with breast cancer. Little is known about the role of physical fitness in attaining an adequate RDI in patients with early-stage breast cancer. We investigated the association between pretreatment physical fitness and RDI in this population. Methods We pooled individual patient data from two randomized exercise trials that studied exercise programs in early breast cancer: the Physical Exercise During Adjuvant Chemotherapy Effectiveness Study (n = 230) and the Physical Activity during Chemotherapy Treatment (n = 204) study. Logistic regression models were used to evaluate the association between pretreatment fitness and achieving an optimal RDI (≥85%). In addition, we added an interaction term to the model to explore the potential moderating effect of participating in an exercise program. Results Data were available for 419 patients (mean age at diagnosis, 50.0 ± 8.6 yr). In the total sample, lower pretreatment physical fitness was associated with significantly lower odds of achieving ≥85% RDI: age-adjusted odds ratio (OR) of 0.66 (95% confidence interval (CI), 0.46–0.94). In patients allocated to the supervised exercise intervention during chemotherapy (n = 173), the association between pretreatment physical fitness and RDI was almost completely mitigated (OR, 0.95 (95% CI, 0.54–1.56)), whereas it was more pronounced in patients who received care as usual (n = 172; OR, 0.31 (95% CI, 0.13–0.63); Pinteraction = 0.022). Conclusions Early-stage breast cancer patients with relatively lower levels of pretreatment physical fitness have lower odds of achieving an optimal dose of chemotherapy. Given that physical fitness is modifiable and our results suggest that following a moderate-to-high intensity exercise training during chemotherapy could improve treatment completion, clinicians should not refrain from referring patients to supportive exercise programs because of low fitness.
Propagação vegetativa de plantas de pariparoba [Pothomorphe umbellata (L.) Miq.] em diferentes substratos e número de nós das estacas

This experiment was carried out at the Department of Plant Production, College of Agronomical Sciences, Sao Paulo State University - UNESP, Botucatu, Sao Paulo State, Brazil, from August to December 2006. The experiment included two types of cuttings, with one and two nodes, and three different substrates: fine sand, soil (Dystrophic Red Latosol) and a mix (soil + cattle manure + commercial substrate + vermiculite, at the proportion 3:1:1:1). The experimental design was in a 2 x 3 factorial arrangement with four replicates in completely randomized blocks. The following biometric variables were analyzed: percentage of plant survival, leaf number and length, besides leaf and root dry and fresh mass. The obtained results were subjected to Analysis of Variance and the means to Tukey's test with 5% probability. Cuttings with one node had higher percentage of plant survival, compared to those presenting two nodes, and cuttings propagated on the mix substrate had higher values of leaf length, and leaf and root dry and fresh mass. Therefore, P. umbellata cuttings with one node are recommended to be propagated on a substrate with the proportions 3:1:1:1 of soil + cattle manure + commercial substrate + vermiculite.
Anterior glottoplasty: the effect of inclusion of the vocal fold lamina propria to frequency elevation

Abstract Background Anterior glottoplasty is a commonly used treatment for voice feminization. But it remains in dispute over whether to suture of the ligament as part of the procedure. Objectives This study aimed to explore the effect of inclusion of the vocal lamina propia. Material and methods Anterior webs were created in 8 excised canine larynges by sutures placed at 10%, 20%, and 30% of the vocal fold length, respectively. The suture depth was divided into two groups: epithelium layer (Shallow Suture, SS group) and deep layers of vocal fold lamina propia (Deep Suture, DS group). Results For anterior webs between 0% and 30%, the frequency elevation ranged from 3% to 151% of the pre-web fundamental frequency (fo) in SS group and from 13% to 222% in DS group. No significance was found between two groups at three different sutures (p = .486 for suture at 10% of vocal fold length, 0.686 for 20%, 0.886 for 30%, respectively). Conclusions and significance The frequency in excised canine larynx increased continuously as the anterior glottic webs ranged from 0% to 30%. The inclusion of the vocal fold lamina propia does not affect the frequency elevation.
Mapping intracellular pH in tumors using amide and guanidyl CEST‐MRI at 9.4 T

In principle, non‐invasive mapping of the intracellular pH (pHi) in vivo is possible using endogenous chemical exchange saturation transfer (CEST)‐MRI of the amide and guanidyl signals. However, the application for cancer imaging is still impeded, as current state‐of‐the‐art approaches do not allow for simultaneous compensation of concomitant effects that vary within tumors. In this study, we present a novel method for absolute pHi mapping using endogenous CEST‐MRI, which simultaneously compensates for concentration changes, superimposing CEST signals, magnetization transfer contrast, and spillover dilution.
