A Recommendation System to Predict Missing Adsorption Properties of Nanoporous Materials

Published: March 2021

Nanoporous materials (NPMs) selectively adsorb and concentrate gases into their pores, and thus could be used to store, capture, and sense many different gases. Modularly synthesized classes of NPMs, such as covalent organic frameworks (COFs), offer a large number of candidate structures for each adsorption task. A complete NPM-property table, containing measurements of the relevant adsorption properties in the candidate NPMs, would enable the matching of NPMs with adsorption tasks. However, in practice the NPM-property matrix is only partially observed (incomplete); (i) many properties of any given NPM have not been measured and (ii) any given property has not been measured for all NPMs.The idea in this work is to leverage the observed (NPM, property) values to impute the missing ones. Similarly, commercial recommendation systems impute missing entries in an incomplete item-customer ratings matrix to recommend items to customers. We demonstrate a COF recommendation system to match COFs with adsorption tasks by training a low rank model of an incomplete COF--adsorption-property matrix. A low rank model, trained on the observed (COF, adsorption property) values, provides (i) predictions of the missing (COF, adsorption property) values and (ii) a "map" of COFs, wherein COFs with similar (dissimilar) adsorption properties congregate (separate). We find the performance of the COF recommendation system varies for different adsorption tasks and diminishes precipitously when the fraction of missing entries exceeds 60%. The concepts in our COF recommendation system can be applied broadly to many different materials and properties.

After coronary illness and all malignancies stroke is the third basic reason for death on the planet.study was aimed to determine the possible relationship between mean corpuscular volume and thrombotic stroke in young people. The study was carried out at a tertiary care hospital. The case-control study was done in 50 patients of young thrombotic cerebrovascular disease and 50 healthy age and sex-matched controls. Estimation of MCV levels was done in both the groups and compared. The mean age of cases was 41.56 ± 9.51. total of 50 cases of young stroke, 36 (72%) was male. The mean and SD values of MCV levels for the case group were 96.78±7.54, for the control group were 82.07±7. Out of the 50 young stroke patients, 17 (34%) had MCV levels ≥101fL. In the control group, all the subjects had MCV levels ≤ 100fL. The mean haemoglobin level was 14.29, with SD ± 1.48 in cases, and the control group mean haemoglobin level was 12.41 with SD±1.39. Mean serum haemoglobin levels were higher in cases than controls. The Significant Macrocytosis (MCV≥100fL) can be a new, low cost and early marker in anticipating the risk of developing thrombotic stroke in young adults who may or may not have anaemia.

O uso intenso do solo e a não adoção de práticas conservacionistas resulta em sua degradação e impactos ao ambiente. Nesse sentido, o presente estudo teve como objetivo avaliar a capacidade de uso e a aptidão agrícola das terras de algumas propriedades rurais da Bacia Hidrográfica do Arroio Pelotas, localizadas no município de Pelotas/RS, utilizando as metodologias propostas, respectivamente, por Lepsch et al. (1991) e Schneider, Giasson e Klamt (2007). Para isso, foram avaliadas três propriedades rurais com pastagem, uma com lavoura e cinco com pomares de pêssego de diferentes idades (0, 2, 6, 8 e 12 anos). A partir dos resultados levantados, verifica-se que as áreas apresentam limitações quanto a capacidade de uso e aptidão agrícola, especialmente relacionadas à pouca profundidade efetiva do solo e, aos riscos de erosão associados à declividade e à textura média na camada superficial do solo. Apesar das limitações quanto ao uso destas áreas, a pastagem e a fruticultura são usos menos intensos de exploração do solo do que as culturas anuais, contudo, ainda se tornam necessárias a implementação de novas práticas conservacionistas do solo e da água ou manutenção daquelas já utilizadas.

Capacity of use and agricultural aptitude of land of rural properties located in the Pelotas River hydrographic basin
Abstract
The intense use of the soil and the failure to adopt conservationist practices, leads to its degradation and impacts on the environment. In this sense, the present study aimed to evaluate the capacity of use and the agricultural aptitude of the lands of some rural properties of the Hydrographic Basin of Arroio Pelotas, located in the municipality of Pelotas/RS, using the methodologies proposed, respectively, by Lepsch et al. (1991) and Schneider, Giasson e Klamt (2007). For this, were evaluated three rural properties with pasture, one with annual crops and five with peach orchards of different ages (0, 2, 6, 8 and 12 years). From the results obtained, the areas have limitations in terms of their use capacity and agricultural aptitude, especially related to the little effective depth of the soil and the risks of erosion associated with the slope and the medium texture in the superficial layer of the soil. Despite the limitations on the use of these areas, pasture and orchards are less intense uses of soil than annual crops, however, it is still necessary to implement new soil and water conservation practices or maintain those already used.

ABSTRACT

Introduction:
The prognosis of patients with persistent or recurrent cervical cancer (CC) is poor, and patient selection for exenterative surgery is challenging. The aim of this study was to determine the outcomes of patients undergoing pelvic exenteration (PE) for persistent or recurrent CC after treatment with radiotherapy in Belarus.

Methods:
A retrospective study was performed of 22 patients with persistent and recurrent CC who underwent supralevator PE from 2006 to 2012 at NN Alexandrov National Cancer Centre. Anterior PE was performed in 16 (72.7%) patients, posterior PE in 2 (9.1%) and total PE in 4 (18.2%) patients.

Results:
The mean surgical procedure time was 289.1 minutes. Urinary diversion was performed in 20 patients: 5 (25.0%) underwent ureterostomy and 15 (75.0%) underwent neobladder formation. Fecal diversion with end colostomy (Hartman’s procedure) was performed in 5 patients and in one patient a rectosigmoid resection with anastomosis was performed.
The median follow-up time was 87 months (range, 4.4–146.0 months). To date, 16 (72.7%) patients have died of cervical cancer and there were no deaths due to other causes. The median survival was 17 months with a 5-year survival rate of 31.8% (SE 9.9%). Cox regression analysis showed that surgical margin status and pelvic lymph node involvement were independent risk factors for survival.

Conclusions:
PE was found to be a safe and feasible option for patients with persistent or recurrent cervical cancer who do not have other potentially curative treatment options. Careful patient selection is needed to determine which patients will benefit from this treatment.

Bullying is one of the serious problems that is vulnerable to occur in adolescence as experienced by students of 9th grade SMPN A Surabaya. Bullying has a variety of negative impacts on victims and people who witness or bystander that see bullying behavior, that is including physical and psychological impacts. Bullying can be overcome by assertive behavior. Assertive behavior makes the victim and bystander able to express opinions straightforwardly and boldly without hurting the offender to stop bullying behavior. Assertive behavior can be enhanced through assertive training. This research was conducted with the aim of seeing the effectiveness of assertive training to: (1) increase students' understanding of bullying and assertive behavior; and (2) increasing assertive behavior of students to be able to overcome bullying at schools. This research is a quantitative research with experimental method. The type of experiments conducted are one group pretest-posttest design. Subjects are selected by purposive sampling. The subjects involved were 25 students in 9th grade students of SMPN A Surabaya. Assertive behavior is measured by the assertiveness scale by Robert E. Alberti and Michael L. Emmons (2002) which has been translated into Indonesian by Nabila (2015). Assertiveness scale is given before and after training for each subject. Subjects underwent 8 training sessions which were held for 2 days. The collected data was analyzed by paired sample t-test. The results show that: (1) there are significant differences in the subject's understanding of bullying and assertiveness before and after the study, where the subject's average understanding increases after training; (2) student assertiveness behavior significantly increases after training. Overall, assertive training is effective for increasing student understanding and effective for enhancing assertive behavior.

Density inversion of selected microgravity anomalies using L2-smoothing and minimum support focusing stabilizers
Authors: ZVARA Ivan , PAŠTEKA Roman , KARCOL Roland 
Published: March 2021

Interpretation and inversion of microgravity anomalies belong to important tasks of near-surface geophysics, mostly in cavities detection in engineering, environmental and archaeological applications. One of the mostly used concepts of inversion in applied gravimetry is based on the approximation of the model space by means of 2D or 3D elementary sources with the aim to estimate their densities by means of the solution of a corresponding linear equation system. There were published several approaches trying to obtain correct and realistic results, which describe real parameters of the sources. In the proposed contribution we analyse the properties of two additional functionals, which describe additional properties of the searched solution – namely so-called L2-smoothing and minimum support focusing stabilizers. For the inversion itself, we have used the regularized conjugate gradient method. We have studied properties of these two stabilizers in the case of one synthetic model and one real-world dataset (microgravity data from St. Nicholas church in Trnava). Results have shown that proposed algorithm with the minimum support stabilizer can generate satisfactory model results, from which we can describe real geometry, dimensions and physical properties of interpreted cavities.

Authors: CHIPADE Radhika A. , RAMANATHAN Thekke Variyam 
Published: March 2021

BeiDou Navigation Satellite System (BDS) is composed of satellites in geostationary Earth orbit (GEO), medium Earth orbit (MEO) and inclined geosynchronous orbit (IGSO). However, the orbit determination of geostationary Earth orbits and of geosynchronous orbits (GSO) with small inclination angle and small eccentricity is a challenging task that is addressed in this paper using Extended Kalman Filter (EKF). The satellite positions were predicted in Earth-centred inertial (ECI) reference frame when propagated through Keplerian model and perturbation force model for different values of right ascension of ascending node (RAAN). Root mean square (RMS) errors of 9.61 cm, 6.73 cm and 11.46 cm were observed in ECI X, Y and Z satellite position coordinates of GSO respectively, whereas, the RMS errors for GEO satellite were 8.89 cm, 7.92 cm, and 0.93 cm respectively in ECI X, Y and Z coordinates; for perturbation force model with maximum value of RAAN when compared with dynamic orbit determination model. Kolmogorov-Smirnov test for EKF reported a p-value > 0.05, indicating a good fit of perturbation force model for orbit propagation. Orbit determination using EKF with perturbation force model were compared with that using EKF with Kepler's model. Wilcoxon Rank Sum test was used to compare the residuals from EKF algorithm through Kepler's model and perturbation force model. EKF with Perturbation force model showed improvement in predicting the satellite positions as compared to Kepler's model. EKF with Perturbation force model was further applied to International GNSS Service (IGS) station data and kilometre level accuracy was achieved. RMS errors of 0.75 km, 2.53 km and 1.91 km were observed in ECI X, Y and Z satellite position coordinates of GSO, respectively, whereas, the RMS errors for GEO satellite were 3.89 km, 4.20 km and 6.66 km respectively in ECI X, Y and Z coordinates for perturbation force model.

OBJECTIVE
For instrumented correction surgery for adolescent idiopathic scoliosis (AIS), surgeons are increasingly switching from titanium (Ti) alloy rods to stiffer cobalt-chromium (CoCr) rods. The authors conducted the first multicenter randomized controlled clinical trial to investigate whether these materials affect the outcomes in terms of spine correction and quality of life (QOL). This trial was registered at UMIN Clinical Trials Registry on September 3, 2012, under the identifier UMIN000008838 (level of evidence 1).

METHODS
Female AIS patients (Lenke types 1–3, patient age 10–19 years) were recruited at 5 Japanese institutions and randomized into two cohorts: 6.0-mm-diameter Ti rods were placed in one group, and 6.0-mm-diameter CoCr rods were placed in the other. Patients were followed up at 2 weeks and 3, 6, and 12 months with radiographic examination to quantify the sagittal and coronal correction (Cobb angle, thoracic kyphosis, rib hump, and apical vertebral rotation). Patients completed questionnaires (Scoliosis Research Society–22r, 12-Item Short-Form Health Survey, and Scoliosis Japanese Questionnaire–27) at 6 and 12 months to assess QOL.

RESULTS
A total of 69 AIS patients were randomized to the demographically similar Ti (n = 37) or CoCr (n = 32) cohort. Four adverse events were recorded, two in each cohort, but these were not related to the rod material. At the final follow-up, both Ti and CoCr cohorts showed significant improvement in spinal correction, including the Cobb angle, thoracic kyphosis, and rib hump size. The correction rates were 68.4% and 67.1% for the Ti and CoCr cohorts, respectively. No parameters differed significantly between the cohorts at any time. Survey data showed improved but similar outcomes in both cohorts.

CONCLUSIONS
Both treatments (Ti and CoCr) produced similar results and were efficient in engendering clinically significant spine corrections.

INTRODUCTION: Atypical intraductal epithelial proliferation (AIDEP) is a breast lesion categorised as “indeterminate” if identified on core needle biopsy (CNB). The rate at which these lesions are upgraded following diagnostic excision varies in the literature. Women diagnosed with AIDEP are thought to be at increased risk of breast cancer. Our aim was to identify the rate of upgrade to invasive or in situ carcinoma in a group of patients diagnosed with AIDEP on screening mammography and to quantify their risk of subsequent breast cancer. METHODS: We conducted a retrospective review of a prospectively maintained database containing all patients diagnosed with AIDEP on CNB between 2005 and 2012 in an Irish breast screening centre. Basic demographic data was collected along with details of the original CNB result, rate of upgrade to carcinoma and details of any subsequent cancer diagnoses. RESULTS: In total 113 patients were diagnosed with AIDEP on CNB during the study period. The upgrade rate on diagnostic excision was 28.3% (n = 32). 6.2% (n = 7) were upgraded to invasive cancer and 22.1% (n = 25) to DCIS. 81 patients were not upgraded on diagnostic excision and were offered 5 years of annual mammographic surveillance. 9.88% (8/81) of these patients went on to receive a subsequent diagnosis of malignancy. The mean time to diagnosis of these subsequent cancers was 65.41 months (range 20.18–145.21). CONCLUSION: Our data showing an upgrade rate of 28% to carcinoma reflects recently published data and we believe it supports the continued practice of excising AIDEP to exclude co-existing carcinoma.
