Feynman diagrams and rooted maps
Authors: Prunotto Andrea , Alberico Wanda Maria , Czerski Piotr 
Published: April 2018

Abstract
The rooted maps theory, a branch of the theory of homology, is shown to be a powerful tool for investigating the topological properties of Feynman diagrams, related to the single particle propagator in the quantum many-body systems. The numerical correspondence between the number of this class of Feynman diagrams as a function of perturbative order and the number of rooted maps as a function of the number of edges is studied. A graphical procedure to associate Feynman diagrams and rooted maps is then stated. Finally, starting from rooted maps principles, an original definition of the genus of a Feynman diagram, which totally differs from the usual one, is given.

Published: April 2018

AbstractIn this paper exact solutions corresponding to the rotational flow of a fractional Oldroyd-B fluid, in an annulus, are determined by applying integral transforms. The fluid starts moving aftert= 0+when pipes start rotating about their axis. The final solutions are presented in the form of usual Bessel and hypergeometric functions, true for initial and boundary conditions. The limiting cases for the solutions for ordinary Oldroyd-B, fractional Maxwell and Maxwell and Newtonian fluids are obtained. Moreover, the solution is obtained for the fluid when one pipe is rotating and the other one is at rest. At the end of this paper some characteristics of fluid motion, the effect of the physical parameters on the flow and a correlation between different fluid models are discussed. Finally, graphical representations confirm the above affirmation.

Abstract
The effect of temperature on the volume change of sand is rarely reported but may be relevant to the performance of energy geostructures. This study involves an investigation of the thermal volume change behavior of saturated, dense sand through a series of temperature-controlled, isotropic hollow cylinder triaxial compression tests. Variables measured during a heating stage include the volume of water expelled from the sand specimen, the temperatures at the top, bottom, and inside of the specimen, and the axial and volumetric strains. The volumes were used along with thermo-elastic relationships for the pore water and soil skeleton to infer the axial and volumetric strains during drained heating. It was observed that the thermally induced axial and volumetric strains were negative, reflecting expansion. The pore water was observed to flow out of the sand specimen during heating, reflecting differential thermal expansion of the pore water and sand particles. The thermal volume changes were observed to be independent of the mean effective stress, as the dense sand specimens were all in normally consolidated conditions. Three linear equations incorporating the effects of temperature on the volume change behavior of dense sand were proposed and match well with the experimental data. The experimental approach proposed in this study can be used in the future to evaluate the role of sand density and stress state on the parameters of these equations.

[only abstract in English; full article and abstract in Lithuanian]
The article discusses mediation in Lithuanian criminal and administrative infringement cases. The challenges of mediation are discussed from the perspective of both the first instance judge and leading scholar in the field of mediation in Lithuania. The article analyzes the practical issues of mediation, questions the legal status of mediation in Lithuanian criminal jurisprudence and shows a good practice of mediation in criminal and administrative infringement cases.Mediation is not the court and does not substitute the court; the final decision is made by the court. Mediation could allow both parties to reach an agreement. However, the victim and the culprit do not always reach for an agreement. It is a beneficial practice in both ways. With the help of a mediator, parties learn how to discuss and hear the other side. It aids in coexisting in non-conflict ways in the future. Foreign experience reveals the most important doubts in the process of mediation that both the victim and the culprit face. The society lacks information on mediation. A high priority should be given for increasing the awareness of the benefits of mediation. Judges represent an authoritative power of the state and should use it in the reconciliation of conflicting parties.Lithuanian criminal justice lacks legislation in the field of mediation; however, mediation is de facto possible if the judge is active. Also, mediators who work at the institutions of probation help to legitimize the institute of mediation.

There has been some great public concern regarding the provision of effective services for delinquent juveniles in order to decrease their untoward behavior and enable them to build further lives without any harm to either themselves or the others. The first results of the effectiveness research of cognitive-behavioral correctional program EQUIP, conducted in United States, where the program was first devised, have shown a great impact of the EQUIP program toward the decrease of delinquent behavior. However, the findings of further investigations in other countries remain controversial.The aim of this study was to measure the impact of the EQUIP program toward the changes of juveniles’ cognitive distortions, social skills and problem behavior at Lithuanian Children Socialization Centers. Quantitative research was conducted to compare the data of the EQUIP and comparison groups before and after the implementation of the EQUIP program. The study involved 124 juveniles (74 males and 50 females) aged 11-17 years. Assuming that the integrity of a correctional program might affect the results of the program’s impact, the following basic components of program integrity (Helmond et al., 2014) where secured while implementing the EQUIP program in Lithuania: 1) Exposure; 2) Adherence; 3) Participant responsiveness; 4) Quality of implementation.The results of the study revealed significant differences of thinking errors, social skills and problem behavior before and after the participation in the EQUIP program, while differences in the abovementioned variables within the comparison group were either absent or insignificant. Based on the results of the study, the intensity of the EQUIP program implementation (5 times per week vs. 4 or less times per week) is an important provision for the increase of the effectiveness of the EQUIP program. Moreover, the age of participants (above 14 years old) is a very important factor to safeguard the changes in cognitive and behavioral variables.It is recommended that further studies on the impact of the EQUIP program are focused on the evaluation of changes of criminal recidivism rates in a long-term perspective as well as criminal attitudes. Moreover, the participation in the EQUIP program should be related to the level of criminal risk, whenever the measure of it is available in Lithuania.

Authors: Tkach V. , Torosov A. 
Published: April 2018

Державна політика у сфері лісокористування, лісовідновлення та збереження лісів формується переважно залежно від динаміки розвитку суспільно-політичних і економічних відносин у країні, ступеня реформування безпосередньо лісових відносин та відповідності лісогосподарської діяльності науково обґрунтованим засадам сталого управління лісами. Розглянуто і визначено основні напрями вдосконалення лісових відносин та реформування системи управління лісовим господарством за її складовими частинами (управління, планування та фінансування) як природного і соціально-економічного об’єкта. Під час реформування лісової галузі України потрібно використовувати європейські моделі удосконалення лісоуправління з урахуванням вітчизняного досвіду і традицій ведення лісового господарства у країні та опиратися на систему науково обгрунтованих рекомендацій.
На початковому етапі реформування потрібно науково обґрунтувати стратегію розвитку галузі, що дасть змогу вирішити питання розвитку лісових відносин у перспективі. Цей етап реформування на галузевому рівні треба розглядати як період, пов’язаний з удосконаленням системи державного управління та формуванням відповідної нормативно-правової бази для забезпечення відповідних перетворень у лісовому господарстві.

Published: April 2018

У загальноєвропейському масштабі тип лісу розуміють як категорію, визначену за складом деревної рослинності та умовами місця росту. Основою лісотипо­ло­гічної класифікації лісової рослинності у гірських країнах Європейського Союзу є природничо-лісова регіоналізація та рангування типів лісу за висотними ступенями рослинності у горах. Подальша диференціація лісового континууму пов'язується з особливостями геологічного підґрунтя, рівнями родючості ґрунтів, ступенями зволоженості та діапазонами її мінливості. Кожен тип лісу у межах конкретного регіону позначається формулою, що містить послідовний ряд абревіатур наведених категорій, який завершується шифром клімаксового лісового рослинного угруповання. Досягнення лісівничих шкіл сусідніх гірських країн у побудові схем системно-структурної диференціації лісового покриву та класифікацій типів лісу можуть слугувати прототипами, за якими варто було б здійснити комплексне удосконалення лісової типології Українських Карпат.
Економічні наслідки всихання ялинників Українських Карпат
Authors: Shparyk Y. 
Published: April 2018

Аналіз результатів стаціонарних досліджень 19-ти деревостанів в основних типах лісу ялинників Українських Карпат дав змогу оцінити економічні наслідки їх всихання. Поточні (в найближчі 10 років) наслідки можуть бути як позитивними, так і негативними: збільшення доходу від зростання обсягів заготівлі деревини; зменшення доходу від втрати вар­тості деревини ялини та від зниження повноти ялинників. Довготермінові наслідки передбачають зменшення доходу від втрати вартості деревини внаслідок зміни породного складу ялинових лісостанів на букові; втрати деревини внаслідок зменшення її приросту; збільшення обороту рубки.
Дохід від заготівлі додаткового обсягу деревини внаслідок всихання ялини визначається інтенсивністю всихання та розподілом ялинників за класами віку і досягає максимуму в умовах вологої чистої сусмеречини (7,45 тис. грн/га за рік) з середнім його значенням 5,35 тис. грн/га за рік. Запізніле проведення санітарно-оздоровчих заходів зменшує цей дохід на 30-40%. Поточні збитки від зменшення радіального приросту стовбурів ялини і зменшення повноти ялинників за типами лісу оцінено від 7,91 (С3-См) до 16,24 (С3-бк-яцСм) тис. грн/га за рік.
Довготермінові наслідки всихання помітно менші від поточних з від’ємним балансом за основними типами лісу, з максимумом в умовах вологої буково-смерекової суяличини (0,73 тис. грн/га за рік) та середнім значенням збитків на рівні 0,23 тис. грн/га за рік. З їх урахуванням середній розмір збитків від всихання ялини в основних типах лісу регіону може досягнути 7 тис. грн/га за рік.

Published: April 2018

O DIEESE – Departamento Intersindical de Estatística e Estudos Socioeconômicos divulga mensalmente o custo da cesta básica referente a todas as capitais do país. Em algumas cidades que não são abrangidas pela pesquisa, algumas Instituições de ensino, tanto públicas como privadas, realizam a pesquisa e divulgam o resultado. Como o município de Taboão da Serra, localizado na região metropolitana de São Paulo, não possui esses dados divulgados, o presente artigo teve como objetivo identificar o custo mensal e médio da cesta básica e verificar a variação de preços de cada produto que compõe a cesta no município de Taboão da Serra em São Paulo. Partindo de uma lista com as quantidades e os produtos definidos pelo Decreto Lei 399 de 1938 e algumas atualizações, no período de janeiro a junho de 2016 foram pesquisados sete estabelecimentos comerciais e aplicado questionário para um grupo de universitários, com o objetivo de identificar quais produtos são mais consumidos. A metodologia da pesquisa envolve a bibliográfica – para definir os principais conceitos e estado em que o tema se encontra; pesquisa de campo – visita aos pontos de vendas escolhidos para levantar os preços dos produtos e pesquisa quantitativa apenas para destacar os valores em tabelas e gráfico para facilitar a análise e interpretação dos resultados. Um dos resultados aponta que no período de janeiro a junho de 2016 o custo mensal médio da cesta básica em Taboão da Serra/SP foi inferior ao custo divulgado para a cidade de São Paulo no mesmo período pelo DIEESE.

Abstract

Background
Deficiencies in the DNA mismatch repair system cause errors during DNA replication, which in turn give rise to microsatellite instability (MSI). The impact of MSI on survival in metastatic colorectal cancer (mCRC) is unclear. This cohort study aims to investigate the prognostic and predictive value of MSI in mCRC prior to the immune therapy era.

Materials and Methods
A total of 75 MSI-high (MSI-H) mCRC patients (pts) and 75 matched (age, gender, disease sidedness, metachronous/synchronous) microsatellite-stable (MSS) mCRC pts were identified from 1,268 mCRC pts who had MSI/mismatch repair test results at Mayo Clinic Rochester between January 1992 and July 2016. A retrospective review was conducted by using data from electronic medical records. Statistical analyses utilized the Kaplan-Meier method, log-rank test, and Cox proportional hazards models.

Results
The MSS group was well matched to the MSI-H group based on age, gender, location, and chronicity of metastatic disease. MSI-H mCRC pts had earlier disease recurrence (median time from initial diagnosis to metastatic disease diagnosis, MSI-H group 12.9 vs. MSS group 20.9 months, p = .034). Median overall survival (OS) was 28.1 and 37.4 months for MSI-H and MSS pts, respectively (p = .99). In total, 94.7% of MSI-H pts and 98.7% of MSS pts had fluoropyrimidine-based chemotherapy for metastatic disease, and there was no difference in OS between these two groups (32.3 vs. 37.4 months, p = .91). Forty-three MSI-H and thirty-nine MSS pts had metastasectomy and/or ablation of metastases (p = .51) with longer median OS compared with pts without metastasectomy (MSI-H: 82.0 vs. 13.9, p &lt; .001; MSS: 69.9 vs. 19.7, p &lt; .001). Age &lt;65 years, BRAF wild type, and metastasectomy were associated with better OS in univariate analysis. Only metastasectomy remained statistically significant in multivariate analysis (p &lt; .001).

Conclusion
In mCRC, patients with MSI-H tumors have similar, but numerically shorter, median overall survival compared with those with MSS tumors. In both groups, metastasectomy and ablation of metastatic disease should be considered to optimize OS.

Implications for Practice
This study clearly demonstrated the survival benefits that aggressive metastasectomy provides in selected microsatellite instability-high metastatic colorectal cancer patients. This could be meaningful practice-changing information that has been long awaited.
Recent Advances in the Treatment of Peripheral T-Cell Lymphoma

Published: April 2018

Abstract

Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of clinically aggressive diseases associated with poor outcome. Despite progress in the last several years, resulting in a deeper understanding of the natural history and biology of PTCL based on molecular profiling and next-generation sequencing, there is a need for improvement in efficacy of chemotherapeutic regimens for newly diagnosed patients. Treatment in the front-line setting is most often cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP-like regimens, which are associated with a high failure rate and frequent relapses. Trials evaluating intensive chemotherapy have resulted in variable success in prolonging event-free survival, but overall survival has remained unchanged. Furthermore, this strategy is limited to patients who are in complete remission after initial anthracycline-based chemotherapy. Many patients are ineligible for hematopoietic stem cell transplantation because of age or failure to achieve remission. For relapsed disease, advances have been made in the therapeutic arsenal for PTCL. New drugs investigated in phase II studies have achieved response rates between 10% and 30%. However, to date the identification of new therapies has been largely empiric, and long-term remissions are the exception to the rule. Current patient outcomes suggest the need for the identification and development of active and biologically rational therapies to improve disease management and to extend the duration of response with iterative biomarker evaluation. This review covers the management of PTCL and focuses on new agents and therapeutic combinations, based on a better understanding of biology and pathogenesis of the disease.

Implications for Practice
Recent progress in understanding of the biology and pathogenesis of peripheral T-cell lymphoma has led to the emergence of new drugs. Unfortunately, this has not been met with similar advances in outcome improvement. Anthracycline-containing regimens, mostly cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), are considered the standard of care, although the best first-line approach remains to be defined. In the relapsed and refractory settings, several new agents achieved response rates between 10% and 30%, although these drugs do not significantly affect survival rates. Therapeutic options based on better molecular characterization of various histological types and combinations with the CHOP regimen or synergic combinations of new drugs may lead to better outcomes.

Abstract

Background
Mantle cell lymphoma (MCL) has the worst prognosis of B-cell subtypes owing to its aggressive clinical disease course and incurability with standard chemo-immunotherapy. Options for relapsed MCL are limited, although several single agents have been studied. Lenalidomide is available in Italy for patients with MCL based on a local disposition of the Italian Drug Agency.

Subjects, Materials, and Methods
An observational retrospective study was conducted in 24 Italian hematology centers with the aim to improve information on effectiveness and safety of lenalidomide use in real practice.

Results
Seventy patients received lenalidomide for 21/28 days with a median of eight cycles. At the end of therapy, there were 22 complete responses (31.4%), 11 partial responses, 6 stable diseases, and 31 progressions, with an overall response rate of 47.1%. Eighteen patients (22.9%) received lenalidomide in combination with either dexamethasone (n = 13) or rituximab (n = 5). Median overall survival (OS) was reached at 33 months and median disease-free survival (DFS) at 20 months: 14/22 patients are in continuous complete response with a median of 26 months. Patients who received lenalidomide alone were compared with patients who received lenalidomide in combination: OS and DFS did not differ. Progression-free survivals are significantly different: at 56 months, 36% in the combination group versus 13% in patients who received lenalidomide alone. Toxicities were manageable, even if 17 of them led to an early drug discontinuation.

Conclusion
Lenalidomide therapy for relapsed MCL patients is effective and tolerable even in a real-life context.

Implication for Practice
Several factors influence treatment choice in relapsed/refractory mantle cell lymphoma (rrMCL), and the therapeutic scenario is continuously evolving. In fact, rrMCL became the first lymphoma for which four novel agents have been approved: temsirolimus, lenalidomide, ibrutinib, and bortezomib. The rrMCL therapeutic algorithm is not so well established because data in the everyday clinical practice are still poor. Lenalidomide for rrMCL patients is effective and tolerable even in a real-life context.
