Controllable multi-agent systems modeled by graphs with exactly one repeated degree
Authors: Alshamary Bader , Anđelić Milica , Dolićanin Edin , Stanić Zoran
Published: September 2024

We consider the controllability of multi-agent dynamical systems modeled by a particular class of bipartite graphs, called chain graphs. Our main focus is related to chain graphs with exactly one repeated degree. We determine all chain graphs with this structural property and derive some properties of their Laplacian eigenvalues and associated eigenvectors. On the basis of the obtained theoretical results, we compute the minimum number of leading agents that make the system in question controllable and locate the leaders in the corresponding graph. Additionaly, we prove that a chain graph with exactly one repeated degree, that is not a star or a regular complete bipartite graph, has the second smallest Laplacian eigenvalue (also known as the algebraic connectivity) in $ (0.8299, 1) $ and we show that the second smallest eigenvalue increases when the number of vertices increases. This result is of a particular interest in control theory, since families of controllable graphs whose algebraic connectivity is bounded from below model the systems with a small risk of power or communication failures.
Robust safe semi-supervised learning framework for high-dimensional data classification
Authors: Ma Jun , Zhu Xiaolong
Published: September 2024

In this study, we introduced an innovative and robust semi-supervised learning strategy tailored for high-dimensional data categorization. This strategy encompasses several pivotal symmetry elements. To begin, we implemented a risk regularization factor to gauge the uncertainty and possible hazards linked to unlabeled samples within semi-supervised learning. Additionally, we defined a unique non-second-order statistical indicator, termed $ C_{p} $-Loss, within the kernel domain. This $ C_{p} $-Loss feature is characterized by symmetry and bounded non-negativity, efficiently minimizing the influence of noise points and anomalies on the model's efficacy. Furthermore, we developed a robust safe semi-supervised extreme learning machine (RS3ELM), grounded on this educational framework. We derived the generalization boundary of RS3ELM utilizing Rademacher complexity. The optimization of the output weight matrix in RS3ELM is executed via a fixed point iteration technique, with our theoretical exposition encompassing RS3ELM's convergence and computational complexity. Through empirical analysis on various benchmark datasets, we demonstrated RS3ELM's proficiency and compared it against multiple leading-edge semi-supervised learning models.
Relocating disaster-prone villages and improving villager well-being: Evidence from Beijing, China
Authors: Wang Jichao , Sui Xiaoning , Zhang Jie , Shi Wenjie , Thompson Wayne L.
Published: September 2024

Relocating disaster-prone villages serves both as a strategy and a method for the Beijing Municipal Government to address the life and work challenges faced by these communities. This approach ensures the safety and security of villagers' lives and property, reduces community and resident vulnerability to disaster risks, enhances resilience, and promotes sustainable development. Using a questionnaire research and disaster sociology perspectives, this study explored the perceptions of the well-being of 360 relocated villagers from ten disaster-prone villages in rural Beijing. Findings show that follow-up support projects, CCP branch secretaries, and community services in these relocated villages significantly improved villagers' well-being. Therefore, we suggest that relocation, the role of the CPC branch, and the development of a diversified social security and service network focused on livelihoods and production are effective in enhancing villagers' well-being.
Celebrating 50 Years of International Consortium for Social Development: Honouring Our Legacy, Shaping Our Future
Authors: Pawar Manohar
Published: September 2024

To celebrate the golden jubilee of the International Consortium for Social Development (ICSD), this article looks at the origin, formation, and purpose of the ICSD, key leaders who led the consortium, its main activities and achievements, and prospects in the years to come. Drawing mainly on the secondary literature and the author’s reflections, the analysis affirms and appreciates that the ICSD was formed on sound grounds and the vision of the leaders who pioneered the ICSD was well thought of as the ideas of social development are increasingly relevant in the contemporary and emerging contexts. Acknowledging the leaders and members who have sustained the consortium for 50 years, it commends its three critical activities: biennial internal conferences; Social Development Issues, a flagship journal of the ICSD; and conceptualizing and theorizing social development, which has contributed to creating and spreading the knowledge of social development worldwide. It also has gradually expanded its activities through its branches. Although there are challenges to articulating its contribution to the theory and practice of social development, ICSD’s role in facilitating it, directly or indirectly, at least to some extent, cannot be denied. The article invites us to pose and ponder, whether the ICSD should have done more and or differently. It argues that such individual and collective reflections help us to envision, plan, and act together for the ICSD, fostering promising futures.
Is nonoperative treatment a valid and successful option for the management of three-part and four-part proximal humerus fractures?
Authors: Waly Mohamed R. , Salah Mohammed M. , El-Shewy Mohamed T. , Hafez Khaled A. , Abdelrazek Begad H.M.Z.
Published: September 2024

Background

Proximal humerus fractures are relatively common, accounting for about 5–9% of all fractures. There is no agreement regarding the optimal interventions for these fractures. This controversy makes a dilemma for decision-makers in the clinic. This study aimed to assess the functional outcome of nonoperative management in Neer’s three, four parts proximal humerus fracture and the incidence of complications.

Patients and methods

This prospective case series study recruited 52 patients with three-part or four-part fractures of the proximal humerus in the Orthopedic Department. Patients were observed and followed up after conservative treatment. Patients of both sexes above 20 years, with closed Neer’s three-part and four-part fractures of proximal humerus, were included. Old (>4 weeks) and open fractures, associated neurovascular injuries, presence of infection, and mentally ill patients were excluded from the study. Ethical approval was obtained from the Institutional Review Board at Cairo University. Written informed consent was obtained from all included patients. American shoulder and elbow surgeon’s score, Constant score, and visual analog scale were assessed at 12 months.

Postinjury radiographs, including true anteroposterior and lateral views, were obtained at 1, 2, 4, and 8 weeks postimmobilization, then at 3, 6, and 12 months following injury.

Results

This study recruited 52 patients with three-part and four-part fractures of the proximal humerus. These patients were managed conservatively, followed up, and observed for 1 year. The mean age of included patients was 64.23 years old (28–87). The majority of included patients were females, 41 (78.8%). Forty-three (82.7%) patients of included patients had three-part fractures and nine (17%) patients had four-part fractures. The age of patients with four-part fractures (75.4 ± 7.8) was higher than the age of patients with three-part fractures (61.6 ± 13.2), and this was statistically significant (P<0.05). The mean Constant score after 12 months was 79.38 ± 8.26 and the American shoulder and elbow surgeon’s was 78.9 ± 11.2. The visual analog score was 3.7 ± 1.7 after 1 year.

Conclusions

Nonoperative treatment of three-part and four-part proximal humeral fractures yield acceptable and satisfactory functional results. Four-part fracture has better clinical results than three-part ones.
Augmentation plate with bone graft in the management of humeral aseptic nonunion after Intramedullary Nailing: Is nail removal mandatory?
Authors: El-Aidy Sherif , Imam Ahmed H. , Safwat Yamen
Published: September 2024

Background

Surgical treatment of aseptic nonunion after intramedullary nail humerus (IMN) offers a wide range of options starting from bone marrow injection to nail removal and usage of alternative fixation methods. There is no consensus regarding nail retaining or nail removal.

Patients and methods

Total 28 patients who had aseptic nonunited fracture humerus after intramedullary nail were treated by a 3.5 locked compression plate using a posterior approach and bone graft with the nail in situ. The study was conducted between January 2019 and December 2022. The age average was 38.6 years old. All nonunions were diaphyseal, with 20 cases having an oligotrophic type while 8 had a hypertrophic type. All nails which were previously used were antegrade with 1 distal locking screw and 2 to 3 proximal locking screws. All nails were seated well without protrusion or encroachment on the supraspinatus tendon. We evaluated pre and post-DASH (Disabilities of arm, shoulder, and hand) scores and visual analog scale (VAS) of pain along with the radiologic union.

Results

The time-lapse between the IMN application and our intervention average was 15.6 months. The patient’s follow-up average was 13.8 months. The final DASH score average was 4.8 (the preop DASH score average was 22). The final VAS pain scale average was 0.6 (the preop VAS pain scale average was 2.8). All cases united after an average of 4.3 months. Two cases had a superficial infection that healed by antibiotics according to culture and sensitivity and repeated dressings.

Conclusion

In this study, surgical treatment obtained excellent clinical and radiological results in aseptic nonunion humerus fractures after IMN failure using 3.5 mm locked compression plate and bone graft with the nail in situ, as long as the conditions of nail retaining are met.
A comprehensive review of challenges and opportunities for stem cell research in India
Authors: Srivastava Kavita , Srivastava Lily , Jain Tanvi
Published: September 2024

Stem cell research is a major focus for scientific and medical communities worldwide due to the potential for stem cells to restore function lost due to disease, trauma, congenital abnormalities, and aging. Stem cells can repair, replace, or regenerate damaged cells, tissues, or organs, making them an important area of research in regenerative medicine. India is emerging as a prominent hub for the development of stem cell therapy (SCT), and it is important to assess the current state of stem cell research in India and the potential for advancement to promote stem cell-based therapy. However, several barriers exist in India that are hindering the rapid expansion of SCT. This article examines the existing regulations that govern SCT in India, comparing them with regulations in developed nations, particularly for patients with unmet clinical needs. It also highlights the importance of public education in dispelling myths, addressing concerns, and promoting the benefits of stem cell research. The article concludes with recommendations for enhancing safety measures in SCT applications to ensure ethical practices and patient well-being.
Geometric rigidity in variable domains and derivation of linearized models for elastic materials with free surfaces
Authors: Friedrich Manuel , Kreutz Leonard , Zemas Konstantinos
Published: September 2024

We present a quantitative geometric rigidity estimate in dimensions

d=2,3

generalizing the celebrated result by Friesecke, James, and Müller [Comm. Pure Appl. Math. 55 (2002), 1461–1506] to the setting of variable domains. Loosely speaking, we show that for each

y \in H^{1}(U;\mathbb{R}^{d})

and for each connected component of an open, bounded set

U\subset \mathbb{R}^{d}

, the

L^{2}

-distance of

\nabla y

from a single rotation can be controlled up to a constant by its

L^{2}

-distance from the group

\mathrm{SO}(d)

, with the constant not depending on the precise shape of

U

, but only on an integral curvature functional related to

\partial U

. We further show that for linear strains the estimate can be refined, leading to a uniform control independent of the set

U

. The estimate can be used to establish compactness in the space of generalized special functions of bounded deformation (

\mathrm{GSBD}

) for sequences of displacements related to deformations with uniformly bounded elastic energy. As an application, we rigorously derive linearized models for nonlinearly elastic materials with free surfaces by means of

\Gamma

-convergence. In particular, we study energies related to epitaxially strained crystalline films and to the formation of material voids inside elastically stressed solids.
„Wieczność wlać w granice małe”. Remigiusza Suszyckiego (1642–1705) wizja zaświatów
Authors: Prabucki Krzysztof
Published: September 2024

The aim of this study is to characterise Pieśni nabożne by Remigiusz Suszycki and to reflect on the vision of the hereafter presented in this poetic cycle. Pieśni nabożne were first printed in 1697 by the print house of Franciszek Cezary the Younger in Kraków. They were subsequently reprinted and supplemented in 1700 and 1702. The collection is internally diverse. The third part, collectively titled Świat górny, contains two genres of works: songs and echoes. On close reading, it is possible to recognise Remigiusz Suszycki’s literary strategy, which consisted in juxtaposing songs and echoes, creating a form of dialogue between two subjects in two corresponding works.

The dialogue that takes place between the two pieces is intended to highlight two different perspectives – the earthly one (representing the human viewpoint) and the heavenly one (showing the vision of the heavenly intelligences). The whole is tied together by an idea related to the tradition of negative theology: throughout Świat górny, unscientific faith is valued positively, while the attitude of man possessing uncertain knowledge is valued negatively, against the background of man’s intellectual achievements in the field of natural science presented in the work. These observations also allow us to present the profile of a little-known author, namely Remigiusz Suszycki. A fuller characterisation of Pieśni nabożne also fills a gap in research on late Baroque religious poetry.
De la réécriture du conte de fées. Politique des contes. Il était une fois Perrault aujourd’hui... d’Alice Brière-Haquet
Authors: Charmion Timothée
Published: September 2024

This review aims to discuss the book Politique des contes. Il était une fois Perrault aujourd’hui... by Alice Brière-Haquet. In this book, after replacing Charles Perrault’s tales in their original context of publication, the author shows how contemporary writers use these tales to put them in resonance with our current times and to express our era and its modernity. That way, she puts an interesting light on the work of Perrault, but also on the challenges involved today in the rewriting of Perrault’s tales. Moreover, her work shows that the parodic rewriting of Perrault’s tales is particularly alive today (the large corpus of these rewritings holds the attention by its ambition and its diversity) but also that the process of rewriting tales is not a specific practice of our contemporary era : indeed, Perrault himself used it in order to invite his readers to interpret political discourses of his time.

Preservation theorems for Tarski's relation algebra
Authors: Bogaerts Bart , Cate Balder ten , McLean Brett , Bussche Jan Van den
Published: September 2024

We investigate a number of semantically defined fragments of Tarski's algebra
of binary relations, including the function-preserving fragment. We address the
question whether they are generated by a finite set of operations. We obtain
several positive and negative results along these lines. Specifically, the
homomorphism-safe fragment is finitely generated (both over finite and over
arbitrary structures). The function-preserving fragment is not finitely
generated (and, in fact, not expressible by any finite set of guarded
second-order definable function-preserving operations). Similarly, the
total-function-preserving fragment is not finitely generated (and, in fact, not
expressible by any finite set of guarded second-order definable
total-function-preserving operations). In contrast, the forward-looking
function-preserving fragment is finitely generated by composition,
intersection, antidomain, and preferential union. Similarly, the
forward-and-backward-looking injective-function-preserving fragment is finitely
generated by composition, intersection, antidomain, inverse, and an `injective
union' operation.
A Refined Laser Method and Faster Matrix Multiplication
Authors: Alman Josh , Williams Virginia Vassilevska
Published: September 2024

The complexity of matrix multiplication is measured in terms of $\omega$, the
smallest real number such that two $n\times n$ matrices can be multiplied using
$O(n^{\omega+\epsilon})$ field operations for all $\epsilon>0$; the best bound
until now is $\omega<2.37287$ [Le Gall'14]. All bounds on $\omega$ since 1986
have been obtained using the so-called laser method, a way to lower-bound the
`value' of a tensor in designing matrix multiplication algorithms. The main
result of this paper is a refinement of the laser method that improves the
resulting value bound for most sufficiently large tensors. Thus, even before
computing any specific values, it is clear that we achieve an improved bound on
$\omega$, and we indeed obtain the best bound on $\omega$ to date: $$\omega <
2.37286.$$ The improvement is of the same magnitude as the improvement that [Le
Gall'14] obtained over the previous bound [Vassilevska W.'12]. Our improvement
to the laser method is quite general, and we believe it will have further
applications in arithmetic complexity.

Published: September 2024

Limb amputation is a process associated with several factors, including traumatic experiences and medical conditions such as diabetes. Physical rehabilitation is essential to improve the independence and quality of life of amputee patients, as well as their psychological well-being. Losing a limb affects social interactions, individuality, and daily activities; it also has an emotional, social, and cognitive impact that can result in mood disorders, including anxiety and depression, challenges adjusting to new jobs, and a decline in quality of life. Consequently, this narrative review examines the therapeutic approaches and strategies that have improved amputee patients’ emotional states, quality of life, ability to adapt, compliance with treatment, and avoidance of risk behaviors.

Authors:   Anaesthesiology and Intensive Care Unit, Hospital Węgrów, Węgrów, Poland., Królak-Ulińska Aneta , Dobrovanov Oleksandr
Published: September 2024

Gram-negative bacteria pose a significant threat as primary agents of infection in septic shock, a condition with high mortality rates in intensive care patients. To combat this, chemists develop antibiotic drugs fortified with protective agents, such as carbapenemase inhibitors, to counter bacterial resistance mechanisms. This study aims to evaluate the clinical efficacy of two antibiotic combinations, imipenem/cilastatin/relebactam (IMI/REL) and piperacillin/tazobactam (PIP/TAZ), in the treatment of septic shock caused by gram-negative bacteria. Seventeen patients diagnosed with septic shock were divided into Group 1 with IMI/REL and Group 2 with PIP/TAZ. All patients received antishock treatment, renal replacement therapy, and ventilation. Bacteriological detection identified four gram-negative pathogens in biological samples, with further phenotyping and genotyping confirming resistance mechanisms.

Los universitarios suelen enfrentarse a una multiplicidad de dificultades escriturales, lo que repercute en su formación, prosecución académica y en la construcción de su perfil como investigador. El objetivo de este estudio fue analizar las prácticas de escritura académica en el género reseña de artículo de investigación escritos por maestros en proceso de formación del Instituto de Formación Docente Salomé Ureña para luego generar una serie de principios reguladores de la alfabetización académica conforme a las tendencias actuales. Metodológicamente, se trata de una investigación descriptiva. La muestra de este estudio fue representada por los estudiantes inscritos en Redacción Académica y Profesional y la prueba piloto por un grupo de Lexicología y Semántica para validar los instrumentos. Se aplicó un cuestionario para explorar sus actitudes sobre el proceso escritural y luego como segundo instrumento se aplicó la prueba de composición en dos momentos. Se usó una lista de cotejo con indicadores que sirvieron de guía para la reescritura del segundo borrador. La información se sistematizó y codificó a través del programa MAXQDA 2022. Los principales resultados evidenciaron que el reconocimiento de los patrones comunicativos refleja mejoras en los escritos de los estudiantes, asimismo la enseñanza explícita es de suma importancia para el desarrollo de esta competencia. No obstante, es relevante señalar que los miedos e inseguridades se siguen manifestando en el proceso, dado que la escritura y la investigación son procesos que ameritan una práctica constante y estas percepciones podrían ir cambiando a largo plazo.
