EXCHANGE RATES AND VOLATILITY IN CENTRAL AND EASTERN EUROPE: A TEST FOR UNCOVERED INTEREST PARITY

RADIO DATA SYSTEM APPLICATIONS

The Radio Data System (RDS) provides a low-rate digital broadcast channel that is specific to the radio station an FM receiver tunes to. While RDS is mainly intended for delivering simple information about the station and current program, we argue that it can be employed to enable a broad range of new applications and enhance existing ones. In this paper, we discuss a number of applications that can be enabled or enhanced by RDS.radio data system.broadcasting, transmission system

Transabdominal pre-peritoneal repair procedure (TAPP) versus open hernia repair (OHR) in the treatment of inguinal hernia

Inguinal hernia is a common condition, with about 30% of men and 6% of women developing this condition throughout their lifetime. Laparoscopic hernia repair procedures have become more and more important lately, due to the advantages of a fast recovery and reduced postoperative pain. The paper presents our clinical experience involving the TAPP repair procedure, compared to open hernia repair (OHR). We retrospectively compared our first 50 cases comprising patients who underwent the TAPP hernia repair procedure between January 2018 and June 2020, with 50 cases who underwent the OHR procedure in the same period. The total operation duration was 102.5 minutes in the TAPP group and 78.4 minutes in the OHR group. The average hospital stay in the TAPP group was 1.5 days with six patients requiring reinterventions for postoperative bleeding and who were discharged seven to nine days later. There is still no consensus regarding the use of tacks and/or the surgical glue, the surgeon\u27s experience and the intraoperative findings representing a cornerstone in choosing the best repair method for each case. Laparoscopic hernia repair has some advantages over the open technique, but it can be followed by complications that can further raise parameters

Clinical and biological factors with prognostic value in acute pancreatitis

Acute pancreatitis is an acute inflammatory process of the pancreas, which can remain localized at the level of the gland or can extend to the peripancreatic and retroperitoneal tissues. The use and interpretation of paraclinical examinations at the onset can predict the form of evolution of acute pancreatitis (mild or severe). Depending on the evolution, these data are useful in determining the type of surgical intervention that might be necessary based on severity. We present a retrospective study consisting of 118 patients diagnosed and hospitalized with acute pancreatitis during 2016-2020 in the Surgery I section of the Sibiu County Emergency Clinical Hospital. Several parameters were taken into account at hospitalization such as age, sex, the environment of origin, etiology of pancreatitis, biochemical parameters with their repetition at 24, 72 hours, and at discharge, and clinical signs at hospitalization. surgeries performed depending on the severity of pancreatitis specifying their complications

Meta-Rationality in Normal Form Games

A new generative relation for Nash equilibrium is proposed. Different types of equilibria are considered in order to incorporate players different rationality types for finite non cooperative generalized games with perfect information. Proposed equilibria are characterized by use of several generative relations with respect to players rationality. An evolutionary technique for detecting approximations for equilibria is used. Numerical experiments show the potential of the method

Sensitive Ants in Solving the Generalized Vehicle Routing Problem

The idea of sensitivity in ant colony systems has been exploited in hybrid ant-based models with promising results for many combinatorial optimization problems. Heterogeneity is induced in the ant population by endowing individual ants with a certain level of sensitivity to the pheromone trail. The variable pheromone sensitivity within the same population of ants can potentially intensify the search while in the same time inducing diversity for the exploration of the environment. The performance of sensitive ant models is investigated for solving the generalized vehicle routing problem. Numerical results and comparisons are discussed and analysed with a focus on emphasizing any particular aspects and potential benefits related to hybrid ant-based models

Laparoscopic versus open surgical treatment of umbilical hernia

Umbilical hernia is one of the types of ventral hernias of the abdominal wall and it represents the externalization of a part of the abdominal contents through a defect of the anterior abdominal wall located in the umbilical region. It is estimated that more than 20 million abdominal wall hernia surgeries are performed worldwide each year. The paper presents a retrospective study on the patients diagnosed with umbilical hernia and admitted to the First and Second Surgery Departments of the Sibiu County Emergency Clinical Hospital. The study includes 82 cases diagnosed with umbilical hernias over a period of 4 years, between 01.01.2017 and 31.12.2020. Open and laparoscopic surgical techniques are compared in terms of outcomes and postoperative complications. Most cases of umbilical hernia were within the age group 51-70 years, with a slightly higher incidence in males. Arterial hypertension and obesity were the most frequent comorbidities. The alloplastic, classic or laparoscopic procedure became the most widely used due to benefits such as: rapid socio-professional reintegration, short-term hospitalization and low incidence of relapses and postoperative complications. The current trend is for the IPOM laparoscopic procedure to become the gold standard in the treatment of umbilical hernias
