Published: November 2023

BACKGROUND

Young people today are exhibiting increasing rates of disordered eating behaviors, as well as eating disorders (EDs), alongside other mental and behavioral problems such as anxiety and depression. However, limited access to mental health care means that EDs, disordered eating behaviors, and comorbid mental health problems are often underdiagnosed and undertreated. Digital mental health interventions (DMHIs) offer accessible and scalable alternatives to traditional treatment modalities, but their effectiveness has not been well established among adolescents with EDs and disordered eating behaviors.

OBJECTIVE

This study uses data from a collaborative care pediatric DMHI to determine whether participation in a DMHI is associated with a reduction in adolescents’ disordered eating behaviors.

METHODS

Adolescent members in care with Bend Health Inc completed the SCOFF questionnaire at baseline (before the start of care) and approximately every month during care to assess disordered eating behaviors. They also completed assessments of mental health symptoms at baseline. Member characteristics, mental health symptoms, and disordered eating behaviors of adolescents with elevated SCOFF scores at baseline (before the start of care) were compared to those of adolescents with nonelevated SCOFF scores at baseline. Members participated in web-based coaching or therapy sessions throughout the duration of mental health care.

RESULTS

Compared to adolescents with nonelevated SCOFF scores (n=520), adolescents with elevated SCOFF scores (n=169) were predominantly female and exhibited higher rates of elevated anxiety and depressive symptoms. SCOFF scores decreased over time in care with the DMHI for 61.4% (n=70) of adolescents with elevated SCOFF scores, and each additional month of participation was associated with greater improvements in disordered eating behaviors (F1,233=72.82; P<.001).

CONCLUSIONS

Our findings offer promising preliminary evidence that participation in mental health care with a collaborative care DMHI may be beneficial in the reduction of disordered eating symptoms in adolescents, including those who are experiencing comorbid anxiety and depressive symptoms.

Telecommunications have an important role in facilitating communication and information exchange, especially in emergency situations such as natural disasters and unexpected community events. Implementing mobile technology is a promising solution to improve the response and handling of in-kind problems. Mobile technology allows the public to quickly report incidents of disaster or security issues through applications or short message services. The implementation of mobile technology facilitates real-time communication between the community and Babinsa. The public can send reports quickly, convey important information, and share photos or videos as evidence of events. Babinsa, on the other hand, can respond more efficiently to these reports and take necessary actions based on the information received. Apart from that, mobile technology also supports two-way communication between Babinsa and the community. The public can also get the latest information about emergencies, efforts handling, or evacuation via app or direct message notification. Thus, the implementation of mobile technology can make a significant contribution to improving communication, response, and handling of disasters and community events.

Sistem monitoring kualitas udara merupakan sistem yang digunakan untuk mengetahui indeks kualitas udara disuatu wilayah. Sensor node merupakan perangkat pengumpulan data berbasis mikroprosesor yang ditempatkan di wilayah yang dimonitor. Terkadang lokasinya berupa area terpencil dengan ketersediaan daya listrik minimal. Padahal sensor node memerlukan daya yang cukup besar terutama saat pengambilan dan pengiriman data. Oleh karena itu, diperlukan suatu sistem penghematan daya. Pada makalah ini dipaparkan sebuah rancangan sistem penghematan daya pada sensor node dengan cara memutus arus ke modul sensor pada saat tidak digunakan untuk pengambilan dan pengiriman data. Rangkaian pensaklaran MOSFET digunakan untuk memutus arus. Pengaturan jeda waktu pengambilan, pengiriman data, dan pengaktifan hemat daya, dilakukan oleh mikrokontroler. Hasil pengujian menunjukkan bahwa terjadi penghematan pemakaian energi pada sensor node sebesar 64 %. Total pemakaian energi yang digunakan selama 5 jam juga terjadi pengurangan, dari yang sebelumnya menggunakan energi sebesar 76.620 Wdtk menjadi sebesar 27.360 Wdtk.

Published: November 2023

Accurate modeling of decoherence errors in quantum processors is crucial for analyzing and improving gate fidelities. To increase the accuracy beyond that of the Lindblad dynamical map, several generalizations have been proposed, and the exploration of simpler and more systematic frameworks is still ongoing. In this paper, we introduce a decoherence model based on the Keldysh formalism. This formalism allows us to include non-periodic drives and correlated quantum noise in our model. In addition to its wide range of applications, our method is also numerically simple, and yields a CPTP map. These features allow us to integrate the Keldysh map with quantum-optimal-control techniques. We demonstrate that this strategy generates pulses that mitigate correlated quantum noise in qubit state-transfer and gate operations.

Hydrogen storage in lithium-decorated single vacancy and Stone-Wales defective silicene: A first-principles investigation
Authors: Sujith Ravindran , Seth Aqshat , Gattu Sai Spoorti , K Sai Srinivasan
Published: November 2023

Defect engineering and metal decoration onto 2-D materials have gained
major attention as a means of creating viable hydrogen storage
materials. This Density Functional Theory (DFT) based study presents
lithium decorated single vacancy (SV) and Stone-Wales (SW) defective
silicene as a viable media for storing hydrogen via physisorption.
Introducing defects increases the Li adatom’s binding energy from -2.36
eV in pristine silicene to -3.44 eV and -2.73 eV in SV and SW silicene,
respectively, thus preventing Li adatom clustering. The presence of
defects and Li adatom further aid hydrogen adsorption onto the
substrates with binding energies present in the US-DOE set range of -0.2
to -0.7 eV/H with the highest binding energy measured
to be -0.389 eV/H . It was seen that both the
Li-decorated defective systems were able to effectively store multiple H
molecules up to 28 H with the
highest gravimetric density being 5.97 wt %. The projected density of
state plots indicates a combined overlap of the Li (p) and Li (s)
orbitals with the H (s) orbital leading to enhanced H
binding energies. Molecular dynamic simulations conducted at 300 K
confirm the stability of the Li adatom as well as the adsorbed H
molecules at room temperature, establishing the

A revised Girvan-Newman clustering algorithm for cooperative groups detection in programming learning
Authors: Chang Wen-Chih
Published: November 2023

Learning to program is a challenging task for novices. Students vary substantially in their ability to understand complex and abstract topics in computer programming logic, such as loop logic, function recursion, arrays, passing parameters, and program structure design. Cooperative learning is an effective method of learning and teaching programming. In traditional cooperative learning, students group themselves, or teachers group students intuitively. This paper proposes a clustering method based on item response theory (IRT) and the revised Girvan?Newman clustering for clustering students by learning ability. Item response theory calculated the learner?s ability and interpersonal relationship questionnaire generated by the social network analysis. The proposed method was validated by conducting a quasi-experimental test in a freshmen programming course, and the method significantly improved learning outcomes in this course.
Knowledge transfer in multi-objective multi-agent reinforcement learning via generalized policy improvement

Even though many real-world problems are inherently distributed and multi-objective, most of the reinforcement learning (RL) literature deals with single agents and single objectives. While some of these problems can be solved using a single-agent single-objective RL solution (e.g., by specifying preferences over objectives), there are robustness issues, as well the fact that preferences may change over time, or it might not even be possible to set such preferences. Therefore, a need arises for a way to train multiple agents for any given preference distribution over the objectives. This work thus proposes a multi-objective multi-agent reinforcement learning (MOMARL) method in which agents build a shared set of policies during training, in a decentralized way, and then combine these policies using a generalization of policy improvement and policy evaluation (fundamental operations of RL algorithms) to generate effective behaviors for any possible preference distribution, without requiring any additional training. This method is applied to two different application scenarios: a multi-agent extension of a domain commonly used in the related literature, and traffic signal control, which is more complex, inherently distributed and multi-objective (the flow of both vehicles and pedestrians are considered). Results show that the approach is able to effectively and efficiently generate behaviors for the agents, given any preference over the objectives.

The recommendation system can alleviate the problem of ?information overload?, tap the potential value of data, push personalized information to users in need, and improve information utilization. Sequence recommendation has become a hot research direction because of its practicality and high precision. Deep Neural Networks (DNN) have the natural advantage of capturing comprehensive relations among different entities, thus almost occupying a dominant position in sequence recommendation in the past few years. However, as Deep Learning (DL)-based methods are widely used to model local preferences under user behavior sequences, the global preference modeling of users is often underestimated, and usually, only some simple and crude user latent representations are introduced. Therefore, this paper proposes a sequential recommendation based on Fusing Session-Aware models and Self-Attention networks (FSASA). Specifically, we use the Self-Attentive Sequential Recommendation (SASRec) model as a global representation learning module to capture long-term preferences under user behavior sequences and further propose an improved session-aware sequential recommendation model as a local learning representation module from user model the user?s dynamic preferences in the historical behavior, and finally use the Gated Recurrent Unit (GRU) module to calculate their weights. Experiments on three widely used recommendation datasets show that FSASA outperforms state-of-the-art baselines on two commonly used metrics.

The rapid growth of network services and applications has led to an exponential increase in data flows on the internet. Given the dynamic nature of data traffic in the realm of internet content distribution, traditional TCP/IP network systems often struggle to guarantee reliable network resource utilization and management. The recent advancement of the Quick UDP Internet Connect (QUIC) protocol equips media transfer applications with essential features, including structured flowcontrolled streams, quick connection establishment, and seamless network path migration. These features are vital for ensuring the efficiency and reliability of network performance and resource utilization, especially when network hosts transmit data flows over end-to-end paths between two endpoints. QUIC greatly improves media transfer performance by reducing both connection setup time and transmission latency. However, it is still constrained by the limitations of single-path bandwidth capacity and its variability. To address this inherent limitation, recent research has delved into the concept of multipath QUIC, which utilizes multiple network paths to transmit data flows concurrently. The benefits of multipath QUIC are twofold: it boosts the overall bandwidth capacity and mitigates flow congestion issues that might plague individual paths. However, many previous studies have depended on basic scheduling policies, like round-robin or shortest-time-first, to distribute data transmission across multiple paths. These policies often overlook the subtle characteristics of network paths, leading to increased link congestion and transmission costs. In this paper, we introduce a novel multipath QUIC strategy aimed at minimizing flow completion time while taking into account both path delay and packet loss rate. Experimental results demonstrate the superiority of our proposed method compared to standard QUIC, Lowest-RTT-First (LRF) QUIC, and Pluginized QUIC schemes. The relative performance underscores the efficacy of our design in achieving efficient and reliable data transfer in real-world scenarios using the Mininet simulator.

Cemented carbide (WC-Co), the widely used tool-die material, is difficult to be machined by conventional and nonconventional techniques. This inspired exploring additive manufacturing (AM) of this material. However, porosity, brittleness due to cobalt depletion, etc. have been reported in the literature with rare success. For the AM of WC-Co, the current work focuses on directed energy deposition, which can be implemented with existing laser cutting-welding workstations, with modifications. To ensure the retention of cobalt even after inevitable vaporization of some of its initial content during deposition, 20 wt. % of Co was mixed with WC powder by low-energy ball milling. Laser power, scan speed, and powder flow rate were varied following a full-factorial design of experiments. The analysis of variance revealed that the experimental model and most of the parameters were significant. Only the laser power came out to be insignificant for the contact angle. The track height and width increased with the laser power and reduced with the scan speed. The contact angle increased with the scan speed and reduced with the powder flow rate. Cross sections of the deposited track showed no pores or cracks. Multiobjective optimization with gray relational analysis was conducted to get the parameter combination giving high values of the contact angle, track height, and width simultaneously. The optimum parameter combination, thus, obtained is 700 W laser power, 5 mm/s scan speed, and 5 g/min powder flow rate. This yielded 305 ± 40 μm track height, 2132 ± 33 μm width, and 152° ± 2° contact angle.
