The coordination of vehicles is a crucial element of autonomous driving, as it enhances the efficiency, convenience, and safety of road traffic. In order to fully exploit the capabilities of such coordination, communication with high data rate and low latency is required. It can be reasonably argued that millimeter-wave (mm-wave) vehicle-to-vehicle (V2V) systems are capable of fulfilling the aforementioned requirements. Nevertheless, in order to develop a system that can be deployed in real-world scenarios and to gain an understanding of the various effects of mm-wave propagation, it is necessary to perform radio propagation measurements and to derive radio channel models from them across a range of scenarios and environments. To this end, we have conducted measurement campaigns at 60 GHz in a variety of situations, including driving in a convoy, driving in opposite direction on a six-lane road, and overtaking. These measurements employ a channel sounder based on ReRoMA, a recently introduced concept that enables the real-time measurement of dynamic double-directional radio channels. The evaluations presented herein encompass key channel parameters, including the path loss (path loss coefficient of approximately 1.9), the root mean square (RMS) delay spread (within a range of 5 ns to 110 ns), the angular spreads (in a range of 0.05 to 0.4), the power distribution among multipath components, and the channel stationarity time (multiple seconds).

SUMMARY Our study aimed to analyze the correlation of cancer-related parameters with tumor regression grade (TRG) and disease-free survival (DFS) by gender in 192 rectal cancer patients operated on after neoadjuvant long-course chemoradiotherapy (LCCRT). Preoperative diagnostics revealed no significant gender differences in any clinical parameters other than obesity (p=0.031). We found that slightly overweight men had a lower incidence of distant metastases (p=0.042). The post-LCCRT pathologic finding showed that women had more positive lymph nodes (ypN, p=0.002) while no other pathologic parameter differed significantly between the genders. Overall, a poor response to therapy correlated with a shorter time to disease progression (p=0.002). Women achieved ypN0 in 50% of cases, but only 27% had a good TRG compared to 40.5% of men (p=0.073). Women had a worse DFS than men, even when complete response to therapy was achieved (p=0.003), and greater depth of residual tumor invasion (ypT, p=0.035) and higher ypN (p=0.002) correlated with shorter DFS. Positive resection margins (p<0.001), higher ypN stage (p=0.003), and poor TRG (p=0.025) correlated with shorter DFS in men. We conclude that women have a poorer response to LCCRT with the possibility that therapeutic approach to the neoadjuvant treatment of rectal cancer may be gender-specific.

Languages do not operate in isolation; rather, they evolve in continuous contact with other languages. This contact and resultant lexical borrowing can lead to minor or substantial changes in the vocabulary of the recipient language. This quantitative study aims to analyze how bor-rowing from the English language affects the formation of new verbs in the Bosnian language (verbal Anglicisms) and which suffixes in the Bosnian language (between -ova-, -a-, -ira-) are most often used to form new verbs. Additionally, the aim is to explore the frequency of use and the level of knowledge of the meaning of verbal Anglicisms. The study was conducted on 345 participants, i.e. both male and female high school students from Bosnia Herzegovina. The results indicate that verbal Anglicisms with the suffix -a- are the most often used group of verbal Anglicisms and that this preference is a result of the nature and origin of those Angli-cisms (mostly IT-related) and is not related to the linguistic nature of the Bosnian language. Furthermore, it was shown that knowledge of the original form of verbal Anglicisms affects the level of their use, and that level of use of these Anglicisms is influenced by the EL GPA and medium of instruction of the respondents, while gender, grade level, and experience of travel-ing to English-speaking countries are not significant factors in the extent of usage of these An-glicisms. Further investigation is proposed to broaden the scope of the present research in different settings and among various study groups. Keywords: Anglicisms; borrowing; language; high school students; verb.

Abstract This study seeks to examine pull factors of capital inflows, offering an empirical analysis based on a panel study of eleven Southeast European countries (Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Montenegro, North Macedonia, Kosovo, Romania, Serbia, and Türkiye) over the period of 2004 – 2021. Methodologically, the study utilizes a fixed effects (FE) regression model with robust Driscoll-Kraay standard errors to address issues of heteroskedasticity, autocorrelation, and potential cross-country correlation. The study finds that several pull factors can be relevant in driving capital inflows as follows: market size, inflation, financial and trade openness. The empirical analysis confirms that the forces of trade liberalization, financial liberalization, market size, real interest rates and inflation stability are the elements that encourage capital inflows. On the other hand, the estimated effects of current account balance and real economic growth are not very convincing. Finally, we stress that more study is required to fully understand the pull variables' ultimate macroeconomic implications at the national level. The overall influence of these positive (or negative) inflows may be moderated by several characteristics, even if certain countries may be extremely susceptible to these factors.

Hydropower is the world's most exploited renewable energy source. It provides a substantial, flexible, and reliable source of renewable energy, complementing other renewables like solar and wind power. Besides conventional hydropower potentials and technologies, the development of technologies for the exploitation of hidden hydropower potentials is an ongoing process. This paper presents the current state of hidden hydropower technologies and links them with possible applications in different hydropower potentials. Technologies and potential applications are structured within three main groups (pressurized systems, hydro storage, unpressurized systems), with their mutual interconnections analysed and displayed throughout the paper. The opportunity for the application of hidden hydropower technologies in different roles within the energy system is recognized through the concepts of off- and on-grid roles, the prosumer concept, and on-site measurement powering. This paper shows that hidden hydropower technologies could emerge as significant contributors to a smoother energy transition, especially with the prosumer and off-grid concepts.

Abstract Environmental, Social, and Governance (ESG) criteria have emerged as pivotal benchmarks for assessing corporate sustainability and ethical business practices. This study investigates the transformative role of small and medium-sized enterprises (SMEs) in advancing ESG practices, with a particular emphasis on countries aspiring to European Union membership. Employing a quantitative methodology through a survey questionnaire the research analyzes the challenges and opportunities associated with ESG implementation. Data collected from 51 SMEs across the Balkan region reveal substantial benefits of ESG integration, notably in enhancing operational efficiency and market reputation, with transparency and strategic planning identified as critical drivers. However, SMEs face significant obstacles such as complex regulatory frameworks, limited access to financing, and inadequate training resources. The article proposes targeted strategies to strengthen SME capacity, emphasizing investment in education, technological solutions, and partnerships with key stakeholders. By adopting ESG standards, SMEs not only contribute to sustainable development but also bolster their competitiveness and resilience in a rapidly evolving global market.

We consider deterministic nonlinear discrete-time systems whose inputs are generated by policy iteration (PI) for undiscounted cost functions. We first assume that PI is recursively feasible, in the sense that the optimization problems solved at each iteration admit a solution. In this case, we provide novel conditions to establish recursive robust stability properties for a general attractor, meaning that the policies generated at each iteration ensure a robust <inline-formula><tex-math notation="LaTeX">$\mathcal {KL}$</tex-math></inline-formula>-stability property with respect to a general state measure. We then derive novel explicit bounds on the mismatch between the (suboptimal) value function returned by PI at each iteration and the optimal one. However, we show by a counterexample that PI may fail to be recursively feasible, disallowing the mentioned stability and near-optimality guarantees. We therefore also present a modification of PI so that recursive feasibility is guaranteed a priori under mild conditions. This modified algorithm, called PI<inline-formula><tex-math notation="LaTeX">$^{+}$</tex-math></inline-formula>, is shown to preserve the recursive robust stability when the attractor is compact. In addition, PI<inline-formula><tex-math notation="LaTeX">$^{+}$</tex-math></inline-formula> enjoys the same near-optimality properties as its PI counterpart under the same assumptions.

In this paper, the author aims to address and problematize the adequacy of the criminal enforcement system in terms of the social adaptation and reintegration of convicted persons after serving a prison sentence, as well as to critically examine the potential problems and risks faced by this population. The humanization of the criminal enforcement system requires respect for the personal integrity and dignity of each individual, along with the implementation of appropriate programs and treatments aimed at behavior change and raising awareness about the harmful effects of criminal activity to achieve specific objectives. In this context, the legislator has prescribed a catalog of rights and established certain rules of conduct, particularly for specific categories, such as minors, individuals with mental disorders, persons with disabilities, and drug users. Special attention is given to juveniles due to their age, criminal-legal status, and the potential risk of recidivism (criminal reoffending), with a particular focus on sentencing and the execution of juvenile imprisonment. Accordingly, the paper centers on the social adaptation and reintegration of former offenders, with a particular focus on the real problems and challenges they face after serving their sentences and being released from correctional institutions.

Abstract Duplication of the vermiform appendix is a rare anomaly observed in patients undergoing appendectomy. A 27-month-old male toddler presented with a 9-day history of abdominal pain, vomiting, and diarrhea, progressing to an acute abdomen with signs of severe peritonitis. Intraoperative findings revealed a periappendicular infiltrate from a perforated vermiform appendix of the tenia coli type. A second, inflamed appendix was incidentally discovered in its typical location during the procedure. Vermiform appendix duplication presents a clinical challenge due to its rarity and potential for complications. According to the Cave–Wallbridge classification, this case represents Type B2, or the tenia coli variant, characterized by a perforated appendix originating at the tenia coli convergence and a smaller, secondary appendix in a retrocecal position. This case emphasizes the importance of thorough distal and proximal exploration during initial appendectomy when this anomaly is suspected, particularly in cases of Type B2.

Cancer progression is an evolutionary process driven by the selection of cells adapted to gain growth advantage. We present a formal study on the adaptation of gene expression in subclonal evolution. We model evolutionary changes in gene expression as stochastic Ornstein–Uhlenbeck processes, jointly leveraging the evolutionary history of subclones and single-cell expression data. Applying our model to sublines derived from single cells of a mouse melanoma revealed that sublines with distinct phenotypes are underlined by different patterns of gene expression adaptation, indicating non-genetic mechanisms of cancer evolution. Sublines previously observed to be resistant to anti-CTLA-4 treatment showed adaptive expression of genes related to invasion and non-canonical Wnt signaling, whereas sublines that responded to treatment showed adaptive expression of genes related to proliferation and canonical Wnt signaling. Our results suggest that clonal phenotypes emerge as the result of specific adaptivity patterns of gene expression.
