We address ionization of a diatomic molecule by a bichromatic elliptically polarized field with co-rotating components. Using the strong-field approximation we investigate symmetry properties of the photoelectron momentum distribution and explore the minima which appear in the photoelectron spectra. We distinguish two types of minima: (i) two-center interference minima which appear due to the destructive interference of the contributions of two electron wave packets emitted from the two centers of the diatomic molecule and (ii) the one-center minima which are caused by the interference of the parts of the wave packet emitted from the same atomic center at different times. The position of the two-center interference minima depends on the molecular orientation. When a molecular orbital is modelled using the atomic orbitals of a specific parity, the position of the two-center interference minima does not depend on the ellipticity of our driving field. However, when a molecular orbital consists of both odd and even atomic orbitals the interference of their contributions and the position of the minima depend on the ellipticity. The position of the interference minima in the photoelectron momentum plane is confirmed using the saddle-point method. The position and the number of the one-center minima do not depend on the molecular orientation, but they strongly depend on the ellipticity of the field components. Finally, comparing the photoelectron spectra of the CO molecule with the spectra of homonuclear molecules and the NO molecule we show that the electron probability density distribution plays a significant role for the high-energy rescattered electrons.
Background Maintenance therapy of patients with primary psychosis spectrum disorders (PSD) in the Western Balkans has received limited interest so far. The present study aimed to investigate long-term prescription patterns among outpatients with PSD. Methods Information about prescription of antipsychotics (AP), benzodiazepines (BZD) and other psychotropic medication over a 6-month period was collected from outpatients (n = 134; ICD-10 diagnosis F20-29) recruited by a larger multi-site study, to find mean daily number of psychotropic drugs, AP prescription patterns (including AP daily dose, route of administration, monotherapy vs. polypharmacy) and BZD utilization (long-term add-on BZD therapy). Additionally, sex-differences in the variables were explored. Results Clinically stable outpatients (age 41.7 ± 11.0; male 62.7%; duration of untreated illness 12.7 ± 8.7 years; mean number of lifetime hospitalizations 2.6 ± 0.7) were prescribed 2.8 ± 1.1 psychotropic medications daily. The mean 6-month AP dose was 14.2 ± 7.8 mg olanzapine equivalents. Long-acting injectable AP was prescribed to 25.2% of the patients. Long-term AP monotherapy was found in 52.7% patients and most of them were prescribed second generation AP (65.2%). Long-term AP polypharmacy (42.7%) was more common in males (p = 0.015). The most frequent co-prescription patterns were first generation AP plus clozapine. The highest rate of long-term AP co-prescription was found for BZD (in 42.7% cases, average 6-months daily dose of 2.8 ± 2.7 mg lorazepam equivalents) and anticholinergics (33.6%). Conclusion Existing appropriately designed interventions aiming to safely switch the inappropriate therapeutic regimens, i.e. very high prevalence of long-term AP polypharmacy and non-rational BZD co-prescription, should be implemented in the region of Western Balkans.
Introduction: Newborn screening (NBS) is a system of organized search in the entire neonatal population for specific diseases. In Bosnia and Herzegovina, two diseases are included in NBS, congenital hypothyroidism (CH), and phenylketonuria. The screening for CH is based on determination of thyroid stimulating hormone (TSH) levels in blood obtained by heel prick method. The aim of this study is to evaluate the effectiveness of NBS program for CH based on TSH and establish the mean age of diagnosis of CH.Methods: TSH was measured by time-resolved fluoroimmunoassay (DELFIA Neonatal hTSH kit). The TSH cutoff value was 9 μU/mL. Neonates with TSH < 9 μU/mL had a negative NBS result. Neonates with TSH ≥ 9 μU/mL were recalled for a confirmation test and thyroid hormones were determined from venous blood to establish diagnosis of CH.Results: A total of 24,351 neonates were subjected to NBS in our institution. A total of 164 newborns with TSH ≥ 9 μU/ml were sent to additional testing (mean recall rate of 0.68%) at a mean age of 11.4 ± 0.5 days of life. In this group, diagnosis of CH was confirmed in 22 neonates (13.41%). The mean rate of false positive results of NBS was 0.59%. The incidence of CH in Sarajevo Canton ranged from 1/2477 in 2018 to 1/641 in 2020. The mean incidence of CH over a 5-year period was 1/1085, while the mean age at the time of diagnosis was 16.5 ± 1.2 days.Conclusion: The analysis of NBS on congenital hypothyroidism data showed the satisfactory recall and false positive rate and indicated well selected TSH cutoff value. The mean age at the time of diagnosis assures early treatment and good neurological outcome in neonates with CH.

This study aims to contribute to the burgeoning field of brain‐inspired computing by expanding it beyond conventional fabrication methods. Herein, the obstacles toward the effective inkjet printing process are encountered and the electrical characteristics are explored, providing new insights into the reliability aspects of fully printed Ag/a‐TiO2/Ag electronic synapses. The versatility of the approach is further enhanced by the highly stable in‐house‐developed a‐TiO2 ink, exhibiting optimal shelf life of five months and repeatable jetting, producing layers with nanoscale thickness resolution. Most importantly, device electrical characterization reveals synaptic dynamics, leading to activity‐dependent conductance state retention and adaptation characteristics, implying inherent learning capabilities. The synaptic dynamics are attained by solely adjusting the duty cycle of the applied pulsed voltage trigger, while keeping amplitude and polarity fixed, a method readily compatible with realistic applications. Furthermore, I–V analysis demonstrates a dynamic range dependence on a‐TiO2 layer thickness and conduction mechanism that is akin to the conventionally developed electronic TiO2 synapses. The developed devices provide a time‐ and cost‐effective ecologically benign alternative toward biomimetic signal processing for future flexible neural networks.
Cleaner production is certainly a challenge of our everyday life, and a lot of effort and energy is required to achieve it. This paper has created a model of five strategies for cleaner production in Libyan industry, which have been evaluated on the basis of eight criteria. In order to determine the significance of the criteria, a novel interval rough SWARA (step-wise weight assessment ratio analysis) method has been developed, which takes into account the preferences of decision-makers (DMs) by applying interval rough numbers. A novel interval rough ARAS (additive ratio assessment) method has been developed for the evaluation and selection of the most favorable strategy for cleaner production. The integration of the developed methods has yielded results showing that the first strategy, launching awareness-raising campaigns to publicize these policies, represents the most realistic and best current solution to achieve cleaner production in Libyan industry. A comparative analysis with some existing interval rough methodologies has been presented to verify the superiority of the proposed model. In addition, in a sensitivity analysis, the weight of the most significant criterion has been changed.
ABSTRACT This paper aims to extend an understanding of the cognitive drivers, namely excitement and sincerity, of brand love and store brand loyalty. It also examines the mediating role of brand love in the relationship between excitement and sincerity, and store brand loyalty. Field research, complemented with mall intercept method, was conducted within eight retail facilities of the biggest trade center in a developing country setting. A total of 450 useful questionnaires were collected and hypotheses were tested using structural equation modeling. The results show that excitement and sincerity, as cognitive drivers, are important predictors of brand love. It has been also proved that brand love fully mediates the relationship between excitement and sincerity, and store brand loyalty. The paper contributes to the retailing and brand–customer relationship literature by revealing new predictors of brand love and store brand loyalty, and enriching the existing, faintly researched brand love mediation body of knowledge in the developing country context. It also highlights the features relevant for a better retail store positioning toward creating store brand loyalty. It is expected that the findings can make changes in store brand positioning, as appropriately positioned store brands could lead to emotional connections and loyalty. More specifically, the findings of the paper highlight which store brand cognitive elements could lead to consumer involvement in the buying process.
The aim of this study was to assess awareness among the students of the Faculty of Dentistry of the University of Sarajevo of the occupational health risks associated with dental profession. The research was conducted among the dental students of all years of study at the Faculty of Dentistry of the University of Sarajevo, by using a tailor-made survey questionnaire. The questionnaire was completed by 446 students. Results: 92% of students believe that dentistry is a profession that involves a high level of risk for the outbreak of occupational diseases. Students believe that practicing dentistry can most often lead to various infections (70%) and vision impairments (64%), and that the most common potential causes of occupational diseases are poor positioning and incorrect body posture during work (88%) and infections (78%). When asked whether the occupational diseases among dentists are preventable, 89% of students gave an affirmative answer, and pointed to the requirement to use Personal Protection Equipment – PPE (94%) as the most important measure for the prevention of occupational diseases among dentists. The results of the survey show that the students of dentistry at the Faculty of Dentistry of the University of Sarajevo have reached a certain level of awareness of the health risks that are associated with their future profession. The students have taken a largely identical view that dentistry is a profession that involves a high level of risk for the development of occupational diseases.
The aim of this study was to examine the content of total soluble substance (TSS), total acidity (TA), pH, ascorbic acid content (vitamin C) and total phenols in fresh strawberries, as well as in strawberries stored for 10 days by freezing. Chemical characterization of fresh and frozen strawberries was done on four different varieties: Clery, Maya, Asia, Joly grown in the area of Čelić, Bosnia and Herzegovina. The obtained results showed that frozen strawberries have slightly lower values of TSS, pH, vitamin C, while the content of TA and total phenols was slightly higher in frozen strawberries than in fresh ones, which can be attributed to increasing acidity.
O presente artigo tem como objetivo denunciar o direito enquanto um campo masculinista, e como essa lógica se reproduz por meio de um ensino jurídico que se estrutura por um tipo de raciocínio que apaga as práticas discursivas e relacionais das mulheres. Em um primeiro momento, por meio dos ensinamentos de Duncan Kennedy (1984), do Critical Legal Studies (CLS), faz-se uma descrição da forma como o ensino jurídico se opera, em especial, ao denunciar o direito como uma prática engajada sócio, política e economicamente, que se reproduz por intermédio de um sistema hierarquizado dessas categorias expostas. Em seguida, questiona-se se essa pirâmide hierárquica não pressupõe, igualmente, uma assimetria de gênero, que se apreende pela configuração do ensino jurídico como uma prática que reproduz paradigmas falocêntricos, como a argumentação e um repúdio pelo particular, pela experiência e pelo contextual. Nesse ponto, debate-se com fundamento nos escritos da autora estadunidense Carrie Menkel-Meadow (1988). Ao final, realiza-se um exercício imaginativo ao propor possíveis mudanças nesse modelo de ensino hierárquico e marcado pelo olhar masculino.
The study was conducted on a sample of 70 deaf children, chronologically aged from 10 to 18 years. Letters of deaf respondents on topics of their choice were used as a measurement instrument. The goals of the research are: To examine the homogeneity of variance of content understanding of written form of expression based on measurements of applied language constructions and content within language discourse, and to determine the statistical significance of content understanding of written form of expression using language constructions within language discourse. The second goal of the study was to examine the connection of language constructions in the applied measurement space of the number of used written expressions in the content understanding of written communication, and to determine the statistical significance of the connection of language constructions in the number of used written expressions in content understanding of written communication. The results of the research showed that the deaf population is characteristic and homogeneous in the way, style of writing and content understanding of the written text observed through linguistic discourse in written dialogue. In the written form of exchange of communication content, a significant degree of communication competence has been achieved, or the comprehensibility of the written form of expression in terms of content understanding. Deaf persons achieve very modest linguistic competence. The reduced ability of deaf children to achieve linguistic competence is reflected through the simplicity of statements in the substantive sense of preferring statements, as one of the characteristics of the linguistic competence of the deaf population.
Noninvasive prenatal testing (NIPT) is the most recent modality widely used in prenatal diagnostics. Commercially available NIPT has high sensitivity and specificity for the common fetal chromosomal aneuploidies. As future advancements in NIPT sequencing technology are becoming promising and more reliable, the ability to detect beyond aneuploidies and to expand detection of submicroscopic genomic alterations, as well as single-gene disorders might become possible. Here we present a case of a 34-year-old pregnant woman, G2P1, who had NIPT screening which detected a terminal microduplication of 10.34 Mb on the long arm of chromosome 15 (15q26.1q26.3). Subsequent prenatal diagnostic testing including karyotype, microarray and fluorescence in situ hybridization (FISH) analyses were performed. Microarray testing confirmed and particularized a copy number gain of 10.66 Mb of the distal end of the long arm of chromosome 15. The G-banding cytogenetic studies yielded results consistent with unbalanced translocation between chromosome 15 and 18. To further characterize the abnormality involving the long arm of chromosome 18 and to map the genomic location of the duplicated 15q more precisely, FISH analysis using specific sub-telomeric probes was performed. FISH analysis confirmed that the extra duplicated segment of chromosome 15 is translocated onto the distal end of the long arm of chromosome 18 at band 18q23. Parental karyotype and FISH studies were performed to see if this unbalanced rearrangement was inherited from a healthy balanced translocation carrier versus being a de novo finding. Parental chromosomal analysis provided no evidence of a rearrangement between chromosome 15 and chromosome 18. The final fetal karyotype was reported as 46,XX,der(18)t(15;18)(q26.2;q23)dn. In this case study, the microduplication of fetal chromosome 15q26.1q26.3 was accurately detected using NIPT. Our results suggest that further refinements in NIPT have the potential to evolve to a powerful and efficient screening method, which might be used to detect a broad range of chromosomal imbalances. Since microduplications and microdeletions are a potential reportable result with NIPT, this must be included in pre-test counseling. Prenatal diagnostic testing of such findings is strongly recommended.
