Balázs Király, György Szabó
We study multiagent logit-rule-driven evolutionary games on a square lattice whose pair interactions are composed of a maximal number of nonoverlapping elementary coordination games describing Ising-type interactions between just two of the available strategies. Using Monte Carlo simulations we investigate the macroscopic noise-level-dependent behavior of the two- and three-pair games and the critical properties of the continuous phase transtitions these systems exhibit. The four-strategy game is shown to be equivalent to a system that consists of two independent and identical Ising models...

We investigate large-scale effects induced by external fields, phenomenologically interpreted as mass media, in multiagent models evolving with the microscopic dynamics of the binary naming game. In particular, we show that a single external field, broadcasting information at regular time intervals, can reverse the majority opinion of the population, provided the frequency and the effectiveness of the sent messages lie above well-defined thresholds. We study the phase structure of the model in the mean field approximation and in numerical simulations with several network topologies...

Central nervous system (CNS) chloromas are an exceedingly rare presentation of CNS relapse in acute lymphoblastic leukemia (ALL). We report a relapsed ALL patient who presented with 2 separate chloromas and cerebrospinal fluid lymphoblastocytosis, and outline a treatment plan of systemic chemotherapy and CNS-directed radiation therapy. A review of the literature indicates that multiagent chemotherapy combined with CNS radiotherapy is effective, with hematopoietic stem cell transplantation used in half of reported cases...

Renal lymphoma is an uncommon renal tumor in children. Unlike renal lymphomas presenting as bilateral disease and renal failure, we report a boy who presented with unilateral renal involvement. After initial nephrectomy, he achieved remission with multiagent chemotherapy but relapsed systemically within 3 months. He was initiated on salvage chemotherapy with autologous bone marrow transplant. Even though the initial manifestation was localized lymphoma eventually, it turned out to be a systemic disease. He succumbed to disease at 14 months from diagnosis...

OBJECTIVES: Gestational trophoblastic neoplasia affects women of reproductive age and is usually treated by chemotherapy. Major concerns related to chemotherapy in young women are the possible infertility, risk of early menopause, and teratogenic effects on subsequent pregnancies. The study's aim was to analyze menstrual and reproductive outcomes of women treated with single-agent versus multiagent chemotherapy for gestational trophoblastic neoplasia. METHODS: One-hundred fifty-one patients were treated...

BACKGROUND: Biological environment is uncertain and its dynamic is similar to the multiagent environment, thus the research results of the multiagent system area can provide valuable insights to the understanding of biology and are of great significance for the study of biology. Learning in a multiagent environment is highly dynamic since the environment is not stationary anymore and each agent's behavior changes adaptively in response to other coexisting learners, and vice versa. The dynamics becomes more unpredictable when we move from fixed-agent interaction environments to multiagent social learning framework...

The use of fever syndromic surveillance in sub-Saharan Africa is an effective approach to determine the prevalence of both malarial and nonmalarial infectious agents. We collected both blood and naso/oro-pharyngeal (NP/OP) swabs from consecutive consenting patients ≥ 1 year of age, with an axillary temperature ≥ 37.5°C, and symptom onset of ≤ 5 days. Specimens were analyzed using both acute febrile illness (AFI) and respiratory TaqMan array cards (TAC) for multiagent detection of 56 different bloodstream and respiratory agents...

BACKGROUND: Brentuximab vedotin is currently approved for patients with relapsed or refractory Hodgkin's lymphoma who previously received an autologous stem cell transplant or two previous multiagent chemotherapy regimens, and for patients with relapsed or refractory systemic anaplastic large-T-cell lymphoma who previously received at least one chemotherapy regimen. A high proportion of patients with CD30-expressing relapsed or refractory lymphomas have durable responses to single-agent brentuximab vedotin and show longer progression-free survival than do patients treated with chemotherapy...

Purpose Although several feasibility studies have demonstrated the safety of adjuvant concurrent chemoradiotherapy (CRT) for locally advanced or incompletely resected non-small-cell lung cancer (NSCLC), it remains uncertain whether this approach is superior to sequential chemotherapy followed by postoperative radiotherapy (C→PORT). We sought to determine the most effective treatment sequence. Patients and Methods Using the National Cancer Database, we selected two cohorts of patients with nonmetastatic NSCLC who had received at least a lobectomy followed by multiagent chemotherapy and radiotherapy; cohort one included patients with R0 resection and pN2 disease, whereas cohort two included patients with R1-2 resection regardless of nodal status...

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare lymphoma entity with an incidence of 0.1 to 0.2/100 000/y. Compared with the more common subtypes of classical Hodgkin lymphoma, NLPHL is characterized by distinct pathological and clinical features. Histologically, the disease-defining lymphocyte predominant cells consistently express CD20 but lack CD30. Clinically, NLPHL mostly has a rather indolent course, and patients usually are diagnosed in early stages. The prognosis of early-stage NLPHL is excellent, with progression-free survival and overall survival rates exceeding 90% after involved-field radiotherapy (IF-RT) alone (stage IA) or combined modality treatment consisting of a brief chemotherapy with 2 cycles of ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) chemotherapy followed by IF-RT (early stages other than stage IA)...

With current available therapies, the prognosis for most children and adolescents with acute lymphoblastic leukemia (ALL) is favorable. However, the multiagent chemotherapy regimens used to treat newly diagnosed patients are associated with many acute and long-term complications, and therapy for relapsed disease is intensive and suboptimally effective. Over the last decade, several nonchemotherapeutic approaches have been evaluated, with the goal of identifying more effective, less toxic therapies that can be used in conjunction with, or even replace, current regimens...

Motohiro Kato, Atsushi Manabe
Acute lymphoblastic leukemia (ALL) is the most common pediatric malignancy. In the past ALL was intractable but now the survival probability is as high as 80-90%. Improved supportive care, treatment stratification based on relapse risk, biological features of leukemic cells, and optimization of treatment regimens by nationwide and international collaboration have contributed to this dramatic improvement. While including traditional risk factors (e.g., age and leukocyte count at diagnosis), the treatment has been modified based on biological characteristics (aneuploidy and translocation) and treatment response (assessed by minimal residual disease)...

We present a novel finite-time average consensus protocol based on event-triggered control strategy for multiagent systems. The system stability is proved. The lower bound of the interevent time is obtained to guarantee that there is no Zeno behavior. Moreover, the upper bound of the convergence time is obtained. The relationship between the convergence time and protocol parameter with initial state is analyzed. Lastly, simulations are conducted to verify the effectiveness of the results.

The interface between mental health services and the criminal justice system presents challenges both for professionals and patients. Both systems are stressed and inherently complex. Section 136 of the Mental Health Act is unusual being both an aspect of the Mental Health Act and a power of arrest. It has a long and controversial history related to concerns about who has been detained and how the section was applied. More recently, Section 136 has had a public profile stemming from the use of police cells as places of safety for young, mentally disturbed individuals...

This paper studies the observer based fault tolerant tracking control problem for linear multiagent systems with multiple faults and mismatched disturbances. A novel distributed intermediate estimator based fault tolerant tracking protocol is presented. The leader's input is nonzero and unavailable to the followers. By applying a projection technique, the mismatched disturbances are separated into matched and unmatched components. For each node, a tracking error system is established, for which an intermediate estimator driven by the relative output measurements is constructed to estimate the sensor faults and a combined signal of the leader's input, process faults, and matched disturbance component...

Mycoplasma gallisepticum (MG) is a bacterial pathogen that causes production losses in layer chickens. To combat MG, multiage layer facilities vaccinate pullets by either spray or eye-drop vaccination. The objective in this study was to evaluate the use of in ovo vaccination as a potential alternative for MG vaccination. Layer embryos at 18 d of incubation were either not-injected (control), or were hand-injected with either commercial Marek's disease vaccine diluent alone or with a high, medium, low, or very low dosage of a live attenuated strain F (FMG) vaccine suspended in the commercial diluent...

Asparaginase is an integral component of multiagent chemotherapy regimens for the treatment of acute lymphoblastic leukemia (ALL). Adequate asparagine depletion is believed to be an important factor in achieving optimal therapeutic outcomes. Measurement of asparaginase activity allows practitioners to evaluate the potential effectiveness of therapy in real time. Asparaginase activity levels can be used to identify patients with silent inactivation and modify therapy in these patients. Patients with silent inactivation to asparaginase who are switched to therapy with an immunologically distinct asparaginase exhibit outcomes similar to patients who never developed silent inactivation...
