Psychodrama Practice in Clinical Social Work with Individuals
Authors: Giacomucci Scott 
Published: February 2021

AbstractThis chapter is devoted to the clinical practice of psychodrama in individual sessions. Fundamental differences between psychodrama in groups and one-to-one contexts are discussed including the use of auxiliary roles, the therapeutic relationship, and modifications for basic psychodrama interventions. An overview of the use of the empty chair, objects, and/or the therapist as an auxiliary ego is included. The limitations and strengths of using psychodrama in individual sessions are discussed. Multiple psychodrama scenes (strengths-based, intrapsychic, and interpersonal) are depicted from a social work practice example with clinical processing.
History of Sociometry, Psychodrama, Group Psychotherapy, and Jacob L. Moreno
Authors: Giacomucci Scott 
Published: February 2021

AbstractThis chapter presents the histories of sociometry, psychodrama, and group psychotherapy while also outlining the history of Jacob L. Moreno, their founder. Major events from Moreno’s life are covered as they relate to the development of his philosophy and the practice of his triadic system, sociometry, psychodrama, and group psychotherapy. The popularity and decline of Moreno’s methods throughout their history are highlighted while offering insights into these historical trends in the USA and globally. Connections are drawn between Moreno’s history and the history of social work while also framing him as a social worker due to the nature of his philosophy, theory, and practice. A comprehensive timeline is offered which depicts the parallel timelines of psychodrama, social work, group therapy, psychology, and society.
Social Work Philosophy Encounters Morenean Philosophy
Authors: Giacomucci Scott 
Published: February 2021

AbstractCore Morenean philosophy is covered in this chapter as it relates to social work philosophy. The existential and spiritual philosophies from which sociometry and psychodrama emerged are comprehensively depicted including his theory of human nature, the encounter, the Godhead, the autonomous healing center within, spontaneity–creativity theory, the here-and-now, action theory, role theory, and psychodrama’s developmental theory. Attention is given to the biopsychosocial -spiritual nature of both social work and psychodrama’s conceptualizations. The intersection of Morenean philosophy is presented with each of the six core social work values—the centrality of human relationships, the dignity and worth of each person, social justice , service, competence, and integrity.
Interpersonal Neurobiology, Social Work, Sociometry, and Psychodrama
Authors: Giacomucci Scott 
Published: February 2021

AbstractThe rapidly emerging neuroscience research continues to validate the practice of social work, group therapy, and psychodrama. The centrality of human relationships is being supported by the field of interpersonal neurobiology. New technologies allow us to learn more about the brain and the ways it is impacted by adversity, healing, and action. The importance of safety, connection, integration, and a strength-s-based approach is supported in the neuroscience literature. The neurobiological mechanisms which promote change in psychodrama are becoming clearer. Furthermore, the words of contemporary neuroscientists appear to echo Moreno’s writings of sociometry and psychodrama nearly a decade earlier.

current algebra and the supertranslations, coming from a positive helicity leading soft graviton, form a closed algebra. We find that the OPE of two graviton primaries in the Celestial CFT, extracted from MHV amplitudes, is completely determined in terms of this algebra. To be more precise, 1) The subleading terms in the OPE are determined in terms of the leading OPE coefficient if we demand that both sides of the OPE transform in the same way under this local symmetry algebra. 2) Positive helicity gravitons have null states under this local algebra whose decoupling leads to differential equations for MHV amplitudes. An n point MHV amplitude satisfies two systems of (n − 2) linear first order PDEs corresponding to (n − 2) positive helicity gravitons. We have checked, using Hodges’ formula, that one system of differential equations is satisfied by any MHV amplitude, whereas the other system has been checked up to six graviton MHV amplitude. 3) One can determine the leading OPE coefficients from these differential equations.This points to the existence of an autonomous sector of the Celestial CFT which holographically computes the MHV graviton scattering amplitudes and is completely defined by this local symmetry algebra. The MHV-sector of the Celestial CFT is like a minimal model of 2-D CFT.
Simulations of a bubble wall interacting with an electroweak plasma
Authors: Mou Zong-Gang , Saffin Paul M. , Tranberg Anders 
Published: February 2021

Abstract
We perform large-scale real-time simulations of a bubble wall sweeping through an out-of-equilibrium plasma. The scenario we have in mind is the electroweak phase transition, which may be first order in extensions of the Standard Model, and produce such bubbles. The process may be responsible for baryogenesis and can generate a background of primordial cosmological gravitational waves. We study thermodynamic features of the plasma near the advancing wall, the generation of Chern-Simons number/Higgs winding number and consider the potential for CP-violation at the wall generating a baryon asymmetry. A number of technical details necessary for a proper numerical implementation are developed.
Hydrodynamic effective field theory and the analyticity of hydrostatic correlators
Authors: Jain Akash , Kovtun Pavel , Ritz Adam , Shukla Ashish 
Published: February 2021

Abstract
We study one-loop corrections to retarded and symmetric hydrostatic correlation functions within the Schwinger-Keldysh effective field theory framework for relativistic hydrodynamics, focusing on charge diffusion. We first consider the simplified setup with only diffusive charge density fluctuations, and then augment it with momentum fluctuations in a model where the sound modes can be ignored. We show that the loop corrections, which generically induce non-analyticities and long-range effects at finite frequency, non-trivially preserve analyticity of retarded correlation functions in spatial momentum due to the KMS constraint, as a manifestation of thermal screening. For the purposes of this analysis, we develop an interacting field theory for diffusive hydrodynamics, seen as a limit of relativistic hydrodynamics in the absence of temperature and longitudinal velocity fluctuations.

Abstract
Purpose
Ultrasound-guided biopsy (US biopsy) with 10–12 cores has a suboptimal sensitivity for clinically significant prostate cancer (sigPCa). If US biopsy is negative, magnetic resonance imaging (MRI)–guided biopsy is recommended, despite a low specificity for lesions with score 3–5 on Prostate Imaging Reporting and Data System (PIRADS). Screening and biopsy guidance using an imaging modality with high accuracy could reduce the number of unnecessary biopsies, reducing side effects. The aim of this study was to assess the performance of positron emission tomography/MRI with 68Ga-labeled prostate-specific membrane antigen (PSMA-PET/MRI) to detect and localize primary sigPCa (ISUP grade group 3 and/or cancer core length ≥ 6 mm) and guide biopsy.

Methods
Prospective, open-label, single-center, non-randomized, diagnostic accuracy study including patients with suspected PCa by elevation of prostate-specific antigen (PSA) level and a suspicious lesion (PIRADS ≥3) on multiparametric MRI (mpMRI). Forty-two patients underwent PSMA-PET/MRI followed by both PSMA-PET/MRI-guided and section-based saturation template biopsy between May 2017 and February 2019. Primary outcome was the accuracy of PSMA-PET/MRI for biopsy guidance using section-based saturation template biopsy as the reference standard.

Results
SigPCa was found in 62% of the patients. Patient-based sensitivity, specificity, negative and positive predictive value, and accuracy for sigPCa were 96%, 81%, 93%, 89%, and 90%, respectively. One patient had PSMA-negative sigPCa. Eight of nine false-positive lesions corresponded to cancer on prostatectomy and one in six false-negative lesions was negative on prostatectomy.

Conclusion
PSMA-PET/MRI has a high accuracy for detecting sigPCa and is a promising tool to select patients with suspicion of PCa for biopsy.

Trial registration
This trial was retrospectively registered under the name “Positron Emission Tomography/Magnetic Resonance Imaging (PET/MRI) Guided Biopsy in Men with Elevated PSA” (NCT03187990) on 06/15/2017 (https://clinicaltrials.gov/ct2/show/NCT03187990).

Published: February 2021

Zusammenfassung
Hintergrund
Sensoren erlauben eine durchgehende Mobilitätsbeobachtung von Patienten nach hüftnahen Frakturen. Fitnessarmbänder ermöglichen unterbrechungs- und einschränkungsarme Längsschnittbeobachtungen der geriatrischen Zielgruppe.

Ziel der Arbeit
Deskriptive Darstellung der Schritte pro Tag (SpT) nach Hüftfrakturoperation auf der geriatrischen Traumastation und darüber hinaus.

Material und Methoden
Die explorative Studie mit Feldcharakter beobachtete über 10 Wochen die SpT von 20 Patienten (80 % weiblich, Durchschnittsalter 85,2 Jahre ± 7,86) via Fitnesstracker. Tägliche Schrittzahlen (SpT) werden für Patienten als wöchentlicher Durchschnittswert (Tage 1–7, 8–14 usw.) gebildet, bevor die deskriptive Analyse erfolgt.

Ergebnisse
Es erfolgt eine positive Entwicklung im Laufe der Beobachtungswochen (BW). Von BW 1 (M = 353,57 ± 310,15) bis 10 (M = 2482,07 ± 1374,12) erfolgt ein durchschnittlicher Anstieg um den Faktor 1,285 (±0,351). Die höchsten Anstiege um das je 1,8-Fache sind von BW 2 (M = 556,27 ± 478,11) auf BW 3 (M = 1024,86 ± 921,24) sowie von 6 (M = 1268,21 ± 880,47) auf 7 (M = 2367,14 ± 1680,08) zu beobachten. Geringfügig verringern sich die Schritte von BW 4 (M = 1208,27 ± 1210,45) auf 5 (0,99-fach) und von BW 9 (M = 2689,98 ± 2339,71) auf 10 (0,92-fach). Es sind stets hohe Spannweiten sowie Standardabweichungen in Anbetracht der Mittelwerte vorhanden. Es lässt auf das Vorhandensein mehrerer Gruppen der Schritteentwicklung schließen.

Diskussion
Fitnesstracker und die Variable SpT können die Gehfähigkeit in der Alltagsumgebung abbilden, bei einem möglichen Unterschätzen < 10 %. Es treten Unterschiede in Beobachtungsdauer sowie -unterbrechungen auf. Eine Clusteranalyse sollte zukünftig Gruppenmerkmale unterschiedlicher Entwicklungsverläufe aufdecken.
Metric Dimension Parameterized By Treewidth
Authors: Bonnet Édouard , Purohit Nidhi 
Published: February 2021

AbstractA resolving set S of a graph G is a subset of its vertices such that no two vertices of G have the same distance vector to S. The Metric Dimension problem asks for a resolving set of minimum size, and in its decision form, a resolving set of size at most some specified integer. This problem is NP-complete, and remains so in very restricted classes of graphs. It is also W[2]-complete with respect to the size of the solution. Metric Dimension has proven elusive on graphs of bounded treewidth. On the algorithmic side, a polynomial time algorithm is known for trees, and even for outerplanar graphs, but the general case of treewidth at most two is open. On the complexity side, no parameterized hardness is known. This has led several papers on the topic to ask for the parameterized complexity of Metric Dimension with respect to treewidth. We provide a first answer to the question. We show that Metric Dimension parameterized by the treewidth of the input graph is W[1]-hard. More refinedly we prove that, unless the Exponential Time Hypothesis fails, there is no algorithm solving Metric Dimension in time $$f(\text {pw})n^{o(\text {pw})}$$

Abstract
Background
Postoperative pancreatic fistula (POPF) and postoperative fluid collection (POFC) are common complications after distal pancreatectomy (DP). The previous method of reducing the risk of POPF was the application of a polyglycolic acid (PGA) sheet to the pancreatic stump after cutting the pancreas with a stapler (After-stapling); the new method involves wrapping the pancreatic resection line with a PGA sheet before stapling (Before-stapling). The study aimed to compare the incidence of POPF and POFC between two methods.

Methods
Data of patients who underwent open or laparoscopic DPs by a single surgeon from October 2010 to February 2020 in a tertiary referral hospital were retrospectively analyzed. POPF was defined according to the updated International Study Group of Pancreatic Fistula criteria. POFC was measured by postoperative computed tomography (CT).

Results
Altogether, 182 patients were enrolled (After-stapling group, n = 138; Before-stapling group, n = 44). Clinicopathologic and intraoperative findings between the two groups were similar. Clinically relevant POPF rates were similar between both groups (4.3% vs. 4.5%, p = 0.989). POFC was significantly lesser in the Before-stapling group on postoperative day 7 (p < 0.001).

Conclusions
Wrapping the pancreas with PGA sheet before stapling was a simple and effective way to reduce POFC.

Published: February 2021

AbstractThis study aimed to conduct a systems engineering investigation for the integration of reverse vending machines (RVM) into the waste management system of Kazakhstan. By conducting a wide-scale survey among the general public, the study was able to identify the underlining reasons for low recycling rate, the awareness and willingness of the public to engage with RVMs, and incentives that would motivate them. Survey results also allowed identifying the customer (user) requirements and helped to design the house of quality (HoQ) for further evaluation of potential RVM functionality. The proposed system model and functional flow block diagram (FFBD) were developed for an RVM considering identified customer requirements. Finally, risk analysis of RVM integration to the waste management system was carried out, and mitigation measures were proposed.
A formal analysis of some factor- and precedent-based accounts of precedential constraint
Authors: Prakken Henry 
Published: February 2021

AbstractIn this paper several recent factor- and dimension-based models of precedential constraint are formally investigated and an alternative dimension-based model is proposed. Simple factor- and dimension-based syntactic criteria are identified for checking whether a decision in a new case is forced, in terms of the relevant differences between a precedent and a new case, and the difference between absence of factors and negated factors in factor-based models is investigated. Then Horty’s and Rigoni’s recent dimension-based models of precedential constraint are critically examined. An alternative to their reason models is proposed which is less expressive but arguably easier to apply in practice.

Published: February 2021

AbstractIt is well over a century that glycosphingolipids are matter of interest in different fields of research. The hydrophilic oligosaccharide and the lipid moiety, the ceramide, both or separately have been considered in different moments as the crucial portion of the molecule, responsible for the role played by the glycosphingolipids associated to the plasma-membranes or to any other subcellular fraction. Glycosphingolipids are a family of compounds characterized by thousands of structures differing in both the oligosaccharide and the ceramide moieties, but among them, the nervous system monosialylated glycosphingolipid GM1, belonging to the group of gangliosides, has gained particular attention by a multitude of Scientists. In recent years, a series of studies have been conducted on the functional roles played by the hydrophilic part of GM1, its oligosaccharide, that we have named “OligoGM1”. These studies allowed to shed new light on the mechanisms underlying the properties of GM1 defining the role of the OligoGM1 in determining precise interactions with membrane proteins instrumental for the neuronal functions, leaving to the ceramide the role of correctly positioning the GM1 in the membrane crucial for the oligosaccharide-protein interactions. In this review we aim to report the recent studies on the cascade of events modulated by OligoGM1, as the bioactive portion of GM1, to support neuronal differentiation and trophism together with preclinical studies on its potential to modify the progression of Parkinson’s disease.
Enhancing large neighbourhood search heuristics for Benders’ decomposition
Authors: Maher Stephen J. 
Published: February 2021

AbstractA general enhancement of the Benders’ decomposition (BD) algorithm can be achieved through the improved use of large neighbourhood search heuristics within mixed-integer programming solvers. While mixed-integer programming solvers are endowed with an array of large neighbourhood search heuristics, few, if any, have been designed for BD. Further, typically the use of large neighbourhood search heuristics is limited to finding solutions to the BD master problem. Given the lack of general frameworks for BD, only ad hoc approaches have been developed to enhance the ability of BD to find high quality primal feasible solutions through the use of large neighbourhood search heuristics. The general BD framework of SCIP has been extended with a trust region based heuristic and a general enhancement for large neighbourhood search heuristics. The general enhancement employs BD to solve the auxiliary problems of all large neighbourhood search heuristics to improve the quality of the identified solutions. The computational results demonstrate that the trust region heuristic and a general large neighbourhood search enhancement technique accelerate the improvement in the primal bound when applying BD.

Published: February 2021

AbstractOceanic squids are typical species that sensitive to the environment change. Previous studies on oceanic squids mainly focus on its annually fluctuated abundance under the background of climate change. The changes of individual morphological sizes, including body and beak, have been observed in recent years. In this study, Ommastrephes bartramii, an important cephalopod species in North Pacific Ocean, has been selected to analyze the annual morphological changes of body and beak under different scales of climate events. Geometric morphometrics was used to analyze the shape variations of both upper beak and lower beak. The possible phenotypic plasticity of body and beak was also discussed in different aspects. Body size showed different variations among different climatic years. The size at the maturity stage in 2015 (El Niño year) was much smaller than that in other years for both sexes. The centroid size representing the beak size showed the significant difference between two types of Pacific Decadal Oscillation phases. The shapes of upper and lower beaks showed significant differences between small-scale climatic patterns in which El Niño or La Niña event occurred, displaying different growth patterns.
Robust Data Integration Method for Classification of Biomedical Data

Published: February 2021

AbstractWe present a protocol for integrating two types of biological data – clinical and molecular – for more effective classification of patients with cancer. The proposed approach is a hybrid between early and late data integration strategy. In this hybrid protocol, the set of informative clinical features is extended by the classification results based on molecular data sets. The results are then treated as new synthetic variables. The hybrid protocol was applied to METABRIC breast cancer samples and TCGA urothelial bladder carcinoma samples. Various data types were used for clinical endpoint prediction: clinical data, gene expression, somatic copy number aberrations, RNA-Seq, methylation, and reverse phase protein array. The performance of the hybrid data integration was evaluated with a repeated cross validation procedure and compared with other methods of data integration: early integration and late integration via super learning. The hybrid method gave similar results to those obtained by the best of the tested variants of super learning. What is more, the hybrid method allowed for further sensitivity analysis and recursive feature elimination, which led to compact predictive models for cancer clinical endpoints. For breast cancer, the final model consists of eight clinical variables and two synthetic features obtained from molecular data. For urothelial bladder carcinoma, only two clinical features and one synthetic variable were necessary to build the best predictive model. We have shown that the inclusion of the synthetic variables based on the RNA expression levels and copy number alterations can lead to improved quality of prognostic tests. Thus, it should be considered for inclusion in wider medical practice.
