Some properties of the closed global shadow graphs and their zero forcing number
Authors: Raksha M. R. , Dominic Charles 
Published: August 2022

Abstract
Zero forcing is one of the dynamic vertex coloring problem. Zero forcing number is the minimum cardinality of the zero forcing sets. This parameter is the upper bound for the maximum nullity. A new class of graph where the maximum nullity is equal to the zero forcing number of the graph is defined as closed global shadow graph. Basic properties and zero forcing number of this graph class is analysed.
A Jurdjevic-Quinn theorem for stochastic differential systems under weak conditions
Authors: Florchinger Patrick 
Published: August 2022

Abstract
The purpose of this paper is to provide sufficient conditions for the stabilizability of weak solutions of stochastic differential systems when both the drift and diffusion are affine in the control. This result extends the well–known theorem of Jurdjevic– Quinn (Jurdjevic and Quinn, 1978) to stochastic differential systems under weaker conditions on the system coefficients than those assumed in Florchinger (2002).
A new approach to maximize the overall return on investment with price and stock dependent demand under the nonlinear holding cost
Authors: Bhadoriya Amrita , Jani Mrudul Y. , Chaudhari Urmila , Tadvi Aniket C. 
Published: August 2022

Abstract
This study investigates an inventory model for deteriorating products with a price and stock-dependent demand pattern where the holding cost is a non-linear function of both time and stock level. Moreover, a decreased price and a higher stock level lead to a higher rate of demand. Consequently, in this article, we present a new approach, aiming at maximization of the return on investment by maximizing the profit/cost ratio. If an inventory manager has the potential to invest in a variety of projects, but disposes of only limited resources, it is logical to strategically plan towards a better return on investment. As a result, the manager’s objective will be to develop an inventory policy with a possibly high return on investment. Therefore, a new strategy is considered in this article to optimize the profitability ratio in terms of replenishment time and selling price, which is determined as the proportion between the profit and the overall cost of the inventory scheme. This research demonstrates that optimizing the profitability ratio is equivalent to decreasing the average inventory cost of a product per unit. Also, the optimality is graphically checked and one numerical illustration is discussed to explain the result of the proposed model. Finally, sensitivity analysis of key parameters is performed to show the applicability of the proposed model. The profit/cost ratio is more sensitive to price elasticity markup or purchasing cost compared to the other parameters used. Also, for decision-makers, several helpful management insights are derived.
A Use Case of Patent Classification Using Deep Learning with Transfer Learning
Authors: Henriques Roberto , Ferreira Adria , Castelli Mauro 
Published: August 2022

Abstract

Purpose
Patent classification is one of the areas in Intellectual Property Analytics (IPA), and a growing use case since the number of patent applications has been increasing worldwide. We propose using machine learning algorithms to classify Portuguese patents and evaluate the performance of transfer learning methodologies to solve this task.

Design/methodology/approach
We applied three different approaches in this paper. First, we used a dataset available by INPI to explore traditional machine learning algorithms and ensemble methods. After preprocessing data by applying TF-IDF, FastText and Doc2Vec, the models were evaluated by cross-validation in 5 folds. In a second approach, we used two different Neural Networks architectures, a Convolutional Neural Network (CNN) and a bi-directional Long Short-Term Memory (BiLSTM). Finally, we used pre-trained BERT, DistilBERT, and ULMFiT models in the third approach.

Findings
BERTTimbau, a BERT architecture model pre-trained on a large Portuguese corpus, presented the best results for the task, even though with a performance of only 4% superior to a LinearSVC model using TF-IDF feature engineering.

Research limitations
The dataset was highly imbalanced, as usual in patent applications, so the classes with the lowest samples were expected to present the worst performance. That result happened in some cases, especially in classes with less than 60 training samples.

Practical implications
Patent classification is challenging because of the hierarchical classification system, the context overlap, and the underrepresentation of the classes. However, the final model presented an acceptable performance given the size of the dataset and the task complexity. This model can support the decision and improve the time by proposing a category in the second level of ICP, which is one of the critical phases of the grant patent process.

Originality/value
To our knowledge, the proposed models were never implemented for Portuguese patent classification.

The effectiveness of the occupational therapy technologies in restoring sensitivity of the paretic upper limb in the early recovery stage of ischemic stroke
Authors: Maykova T. V. , Afanasyev S. M. 
Published: August 2022

Aim. To restore the sensory functions of the paretic upper limb in patients with post-stroke hemiparesis by applying the occupational therapy in order to improve the ability to daily activities and independence.Material and methods. Under observation there were 63 patients with post-stroke hemiparesis. The level of sensory functions of the upper limb was determined using the tests recommended by the European Stroke Organization for stroke control in clinical practice.Results. While developing the program of the occupational therapy intervention a correctional and developmental strategy was chosen. Patients were randomized into 2 groups. In the main group the “mirror” therapy was used, it was combined with the art therapy. At the beginning, the “mirror” therapy was used for 1 month, followed by the functional tasks and the art therapy. As a result of the program applied, the sensory functions of the upper limb were completely restored or significantly improved in the vast majority of patients, which led to recovery and improvement of its dexterity.
Conclusions. Sensory insufficiency of the paretic upper limb, which is formed during ischemic stroke, is a limiting factor in restoring its motor activity in the vast majority of patients, and it hinders independence in their domestic and professional activities.The use of the “mirror” therapy as a key trigger, a starting factor to stimulate the mechanisms of neuronal plasticity with further addition of the art therapy, with the purposeful application of tasks for training of proprioceptive and perceptual qualities, made it possible to restore or significantly improve the sensory functions of the paretic upper limb and its dexterity.Key words: ischemic stroke; occupational therapy; recovery of sensitivity.

Authors: Neeley Darren K. , George Steven Z. , Minick Kate , Snow Greg , Brennan Gerard 
Published: August 2022

OBJECTIVE: To predict 30- and 180-day improvements in disability and pain for patients seeking physical therapy care for low back pain (LBP). DESIGN: Longitudinal cohort. METHODS: Baseline assessment was completed by 259 patients with chief complaint of LBP, and the assessment includes psychosocial measures (Keele STarT Back Screening [SBST] and the Optimal Screening for Prediction of Referral and Outcome Yellow Flag [OSPRO-YF] tools), the Optimal Screening for Prediction of Referral and Outcome Review of Symptoms (OSPRO-ROS) and the Review of Symptoms Plus (OSPRO-ROS+) tools, the Charlson Comorbidity Index (CCI), the Area Deprivation Index (ADI), and the National Institute of Health Chronic Pain Criteria (NIH-CP). Using the Modified Low Back Disability Questionnaire (MDQ) and the Numeric Pain Rating Scale (NPRS) as primary outcomes, statistical analysis determined multiple sets of predictor variables with similar model performance. RESULTS: The parsimonious “best model” for prediction of the 180-day MDQ change included 3 predictors (Admit MDQ, NIH-CP, and OSPRO ROS+) because it had the lowest penalized goodness-of-fit statistic (BIC = −35.21) and the highest explained variance (R2 = 0.295). The parsimonious “best model” for 180-day NPRS change included 2 variables (Admit NPRS and OSPRO-ROS+) with the lowest penalized goodness-of-fit statistic (BIC = −18.2) and the highest explained variance (R2 = 0.190). CONCLUSION: There were many model options with similar statistical performance when using established measures to predict MDQ and NPRS outcomes. A potential variable set for a standard predictive model that balances statistical performance with pragmatic considerations included the OSPRO-ROS+, OSPRO-YF, NIH-CP definition, and admit MDQ and NPRS scores.

Published: August 2022

Background:
Preoperative optimization in patients undergoing posterior spinal fusion is essential to limit the number and severity of postoperative complications. Here, we, additionally, evaluated the impact of hypoalbuminemia on morbidity and mortality after posterior spinal fusion surgery.

Methods:
This retrospective analysis was performed using data from a prospective multicentric database (ACSNSQIP:2015–2020) regarding patients undergoing posterior spinal fusions. Factors studied included; baseline demographics and 30-day postoperative complications (i.e., reoperations, readmissions, and mortality rates).

Results:
There were 6805 patients who met the inclusion criteria. They averaged 62 years of age and had an average BMI of 30.2. Within the 30-day postoperative period, 634 (9.3%) sustained complications; 467 (6.9%) were readmitted, 263 (3.9%) required reoperations, and 37 (0.5%) expired. Although multiple preoperative risk factors were analyzed, hypoalbuminemia, severe hypoalbuminemia, and dialysis were the strongest independent risk factors associated with complications (i.e., reoperations, readmissions, and mortality).

Conclusion:
Hypoalbuminemia, severe hypoalbuminemia, and dialysis were significant predictors for morbidity and mortality after posterior spinal fusion surgery.

Authors: Balutkina Natalya A. , Stukalova Anna A. 
Published: August 2022

In contemporary information space, repository formation is one of the urgent tasks of libraries of scientific and educational institutions. Institutional repositories (IRs) provide unhindered access to scholarly works posted by scientists and specialists for general user, increasing the demand for the library's information resources.The article represents the review of foreign and domestic publications on the formation and development of institutional repositories. The authors consider the advantages of forming Open Access (OA) Repositories both among prospective authors and potential users: archiving and keeping materials in the IR up-to-date, ensuring visibility and possibility of using scientific research through global access, rapid dissemination of research results, increasing the citation of submitted materials, growth of prestige of the organization, the development of scientific communication, etc. The authors found out that placing publications in international archives (arXiv, BioXiv, etc.) or corporate projects (BASE, HathiTrust) has a greater impact on the visibility and potential citation of publications.The article identifies the problems of formation and use of repositories: labour intensity of content placement process, the complexity of data exchange, copyright management, the lack of incentives in providing information about their scientific work, the need for additional time and labour resources when maintaining the IR, the financial costs of maintaining the repository, and the difficulties of search in the IR. The authors note that the IR functionality depends on the software capabilities. The paper gives the examples of new generation repositories and presents their features: self-filling, automatic classification based on text mining and machine learning, data management processes between different systems, easy-to-use interfaces.

O ESPECTRO DO SILÊNCIO NA DINÂMICA FAMILIAR À LUZ DO FILME O VAZIO DO DOMINGO
Authors: Oliveira Laura Souza Eletherio de , Machado Rebeca Nonato 
Published: August 2022

RESUMO
No contexto da psicoterapia de família, a investigação sobre a comunicação é uma dimensão crucial para o entendimento da dinâmica familiar. As interações familiares são permeadas de mensagens verbais e afetos, representados por experiências de silêncio que estabelecem sentidos singulares na convivência íntima entre os membros. Diante da complexidade do fenômeno do silêncio nas interações humanas, este estudo tem como objetivo refletir os significados variados e os desdobramentos do silêncio na interação familiar, a partir da revisão de literatura no campo da psicoterapia de família, em suas abordagens sistêmicas e psicanalíticas. Para complementar a discussão, analisamos o filme “O Vazio do Domingo” (2018), utilizando o método análise temática a fim de ilustrarmos o espectro do silêncio. Refletiu-se que existe um silêncio na interação do grupo familiar de caráter repousante, desvelando o ápice da intimidade amorosa humana. Por outro lado, também há o silêncio que evidencia a perturbação dos vínculos e afetos, manifestando uma experiência emocional conflituosa, favorecendo a manutenção de um sofrimento compartilhado insuportável de ser vivenciado e representado.
