Isolated Q-learning for Offline Reinforcement Learning
Authors: Zhang Huihui , Han Xu 
Published: May 2024

Abstract

Conventional online reinforcement learning (RL) systems interact with their environments to gather data, aiming to develop an optimal policy that maximizes a predefined cumulative reward. Nevertheless, the applicability of online RL is limited under conditions where cost and safety are critical concerns. Offline RL emerges as a solution by leveraging previously collected datasets to derive an effective policy without further interacting with the environment. A significant hurdle in offline RL is the propensity to overestimate the values of actions not represented in the data (out-of-distribution, or OOD actions), often due to insufficient exploration of the state-action space. Prior works tend to add to the algorithm complexity to improve the performance, however, this paper halves the algorithm computation as well as gaining performance improvement.In this paper, we delve into the inaccuracies associated with isolated critic training, devoid of policy enhancement typically driven by actor training. We hypothesize that the dataset's inherent Q-values (behavior Q-values) may be more accurate than those derived from actor-critic cycles, which are susceptible to overestimation and volatility.Upon validating the dataset Q-values' reliability, we propose pre-training models to capture these values before commencing offline training, potentially streamlining algorithmic efficiency across various models and reducing computational demands.Moreover, by harnessing precise dataset Q-value estimations, we advocate for a conservative approach to offline training, which demonstrably mitigates value overestimation.Our methodologies have the potential to be generalized among offline RL and may show a new perspective on the ways of optimizing the offline learning.
Knockdown Resistance (kdr) Associated Organochlorine Resistance in Mosquito-Borne Diseases (Anopheles subpictus): Systematic Reviews Study
Authors: Abbasi Ebrahim , Daliri Salman 
Published: May 2024

Abstract

Introduction: Anopheles subpictus is one of the main vectors of malaria in East Asia, and Australia. One of the important obstacles to fighting against this vector is knockdown resistance, which prevents the effectiveness of insecticides. Based on this, the present study was conducted to survey the resistance of Anopheles subpictus against organochlorine insecticides in the world in a systematic review.
Material and methods: This study was conducted in the field of knockdown resistance, and related mutations in Anopheles subpictusagainst organochlorine insecticides by systematic review method. In the international databases Web of Science, Scopus, PubMed, Bioone, ProQuest, and Embase, all articles published until the end of May 2023 were extracted, and reviewed.
Results: Four articles on KDR in the Anopheles subpictuswere included in the systematic review process. Based on the findings, kdr in Anopheles subpictus was reported against organochlorine toxins in India, Pakistan, and Sri Lanka, but no resistance was observed in Mekong Delta. In this vector, the range of the kdr ratio was between 70 and 90%. Resistance to organochlorine pesticides was originally noted in India and then spread to Sri Lanka and Pakistan due to the L1014F mutation.
Conclusions: Based on the findings, a lot of proportion of Anopheles subpictus has resistance to organochlorine insecticides and this resistance has spread to other areas where this vector operates. Hence, it is necessary to use combined insecticides to fight this vector.

Abstract

This paper investigates performance optimization of Gaussian mixture algorithms in the context of mathematical analysis. Using advanced optimization methods, adapted to the specific requirements of mathematical problems, we investigate how to improve the efficiency and precision of Gaussian mixture algorithms. Through experimental results and analyses, we demonstrate the benefits of these optimizations on various applications of mathematical analysis.
In addition, we focus on developing new techniques to address challenges arising from the application of Gaussian mixture algorithms in mathematical analysis, such as overlearning and scalability problems. Through detailed experiments on different data sets and mathematical analysis problems, we provide deeper insight into the performance and applicability of the optimized algorithms. Our work also highlights the importance of the adaptability of algorithms in different contexts of mathematical analysis and the need for continuous improvement of optimization methodologies in order to adequately respond to the dynamic demands of the research community..
Focus on Non-osteoporotic Post-menopausal Women with Asymptomatic Primary Hyperparathyroidism: A Monocentric Series
Authors: Castellano Elena , Attanasio Roberto , Boriano Alberto , Gianotti Laura , Borretta Giorgio 
Published: May 2024

Objective:
Primary Hyperparathyroidism (PHPT) is a common disease, frequently
diagnosed in post-menopausal women, among whom Osteoporosis (OP) is a common finding.
To date, no study has specifically evaluated the asymptomatic PHPT (aPHPT) patients without
OP, in particular post-menopausal women who are exposed to an increased risk of developing
OP.

Materials and Methods:
This study involved a retrospective cross-sectional evaluation. From
our database of 500 consecutive patients diagnosed with PHPT, 178 post-menopausal aPHPT
were retrieved.

Results:
The clinical, biochemical, and imaging data of the 85 patients without OP were not
different from those of the 93 with OP, except for bone alkaline phosphatase (significantly
higher in the latter group). Among these 85 patients without OP, the 45 patients meeting surgical
criteria for parathyroidectomy had significantly higher values of serum PTH (240 vs. 99
ng/L, p =0.03) and calcium (total, 11.2 ± 0.7 vs. 10.6 ± 0.4 mg/dL, p <0.001; ionized, 1.45 ±
0.12 vs. 1.36 ± 0.8 mmol/L, p =0.044) and lower values of serum phosphate (2.57 ± 0.7 vs. 2.94
± 0.5 mg/dL, p =0.009) and eGFR (68.5 ± 23.8 vs 80.8 ± 14.4 mL/min/1.73 m2, p =0.006) than
the 40 aPHPT patients not meeting surgical criteria, without any difference in densitometric
data and calculated fracture risk.

Conclusion:
In our series, post-menopausal aPHPT patients without OP accounted for almost a
sixth of the whole PHPT series. About half of these patients did not meet surgical criteria, but
their T scores and 10-year fracture risk calculated by FRAX were not significantly different
from post-menopausal aPHPT without OP meeting surgical criteria.

Published: May 2024

Background
Care partners of people with serious illness experience significant challenges and unmet needs during the patient’s treatment period and after their death. Learning from others with shared experiences can be valuable, but opportunities are not consistently available.

Objective
This study aims to design and prototype a regional, facilitated, and web-based peer support network to help active and bereaved care partners of persons with serious illness be better prepared to cope with the surprises that arise during serious illness and in bereavement.

Methods
An 18-member co-design team included active care partners and those in bereavement, people who had experienced serious illness, regional health care and support partners, and clinicians. It was guided by facilitators and peer network subject-matter experts. We conducted design exercises to identify the functions and specifications of a peer support network. Co-design members independently prioritized network specifications, which were incorporated into an early iteration of the web-based network.

Results
The team prioritized two functions: (1) connecting care partners to information and (2) facilitating emotional support. The design process generated 24 potential network specifications to support these functions. The highest priorities included providing a supportive and respectful community; connecting people to trusted resources; reducing barriers to asking for help; and providing frequently asked questions and responses. The network platform had to be simple and intuitive, provide technical support for users, protect member privacy, provide publicly available information and a private discussion forum, and be easily accessible. It was feasible to enroll members in the ConnectShareCare web-based network over a 3-month period.

Conclusions
A co-design process supported the identification of critical features of a peer support network for care partners of people with serious illnesses in a rural setting, as well as initial testing and use. Further testing is underway to assess the long-term viability and impact of the network.
Near-real-time Identification of the Source of Ionospheric Disturbances
Authors: Maletckii Boris , Astafyeva E 
Published: May 2024

The ionosphere is characterised by a large number of disturbances
generated in response to a wide range of phenomena, including natural
hazards, space weather and man-made events. Such disturbances are known
as travelling ionospheric disturbances (TID). Identification of the
origin of TID, especially in real or near-real-time (NRT), is an
extremely difficult task, and it is one of the most interesting
scientific questions. In this paper we present, for the first time, an
approach for an automatic and NRT-compatible detection and recognition
of the source of ionospheric disturbances in time series of total
electron content (TEC) measured by the Global Navigation Satellite
Systems (GNSS) method. The main idea is 1) to analyse main
characteristics (such as spatio-temporal features and frequency content)
of TID generated by known sources, and 2) in NRT, to rapidly examine
TID’s, and, based on this information, recognize their source.
Currently, our database contains TEC data series with response to
earthquakes, volcanic eruptions, tornadoes, explosions, rocket launches
and equatorial plasma bubbles. Our developments are important for the
future assessment of natural hazards from the ionosphere, and also for
NRT Space Weather nowcast and applications. Also, our work presents
important information about the physical properties of TID of different
origins.

Authors: Peraza-Balderrama José Néstor , Valdés-Cuervo Ángel Alberto , Parra-Pérez Lizeth Guadalupe , Urías-Murrieta Maricela 
Published: May 2024

The study examined the psychometric properties of a Digital Security Scale (DSS-A) in a sample of 868 adolescents (460 female, 408 male), made up of 424 early adolescents (M age = 11.84 years, SD = 0.36) and 444 middle adolescents (M age = 13.44, SD = 0.49). The sample was randomly split into two for validation (n = 434) and cross-validation (n = 434) purposes. The results confirmed the fit of a one second-order factor model with four first-order factors (personal data protection, safe relationships, healthy internet use, and self-disclosure). As expected, digital security dimensions were positively associated with parental mediation. Measurement invariance was found in this model by gender and stage of adolescence. Latent mean comparisons showed differences by gender and stage of adolescence. Overall, findings indicate that the measurement model is helpful for measuring adolescents’ digital security behaviors.

Separation of Surety Agreement and Guarantee Agreement
Authors: Aktaş Murat Ali 
Published: May 2024

Objective: The purpose of this research is to learn the differences between the “Surety Agreement” and the “Guarantee Agreement”, which are often confused in collateral law.

Method: The research method used in this study was based on finding the general result to be obtained after comparing the opinions of academics with court decisions based on domestic legal rules in Turkey.

Results and Discussion: In contracts established in commercial and social life, there are remedies such as "Surety Agreement" or "Guarantee Agreement" to eliminate or significantly reduce the risk of the debtor's inability to pay the debt. It has been concluded that the Guarantee Agreement provides a stronger guarantee than the Surety Agreement, is established by a different contract from the articles of association, the creditor has the right to apply directly to the guarantor in the articles of association, and in case of hesitation, he has the right to apply to the guarantor. there is a practice and consensus on this issue before the Turkish courts and academics.

Research Implications: The information and documents that can be used in this research have been obtained completely from open sources. all of the quoted information is written in the footnotes and bibliography section.

Originality/Value: The novelty of this research is that it explains the reasons for using the “Bank Guarantee Letter”, the most well-known example of which is due to the fact that the Guarantee Agreement provides more effective protection to the creditor party in the field of collateral law.
História imediata e participante da formação de professores na cidade de São Paulo (2001-2004)
Authors: Pisaneschi Lucilene Schunck Costa , Bauer Carlos 
Published: May 2024

Este artigo apresenta a história imediata de uma experiência formativa de professores vivenciada, entre os anos de 2001 e 2004, no âmbito da Secretaria Municipal de Educação de São Paulo (SME-SP), em um momento em que a formação docente tinha como pressuposto para sua construção o princípio da autonomia defendido por Paulo Freire. O relato estabelece um diálogo entre o pensamento de Adorno e Freire no que diz respeito às categorias de autonomia e emancipação, cortejado por premissas marxianas em torno do papel do indivíduo na história. Também se tem como finalidade a compreensão da importância e dos limites presentes na experiência de formação em serviço dos professores desta conceituada rede municipal de ensino brasileira, operada nos primórdios do século XXI.
