Epigrafski miljokazi i njihov značaj za proučavanje rimskih komunikacija na jugu provincije Dalmacije / Epigraph Milestones and Their Significance for the Research on the Roman Roads in the South of the Province of Dalmatia
Authors: M. Samardžić Gligor 
Published: November 2021

The paper presents data on epigraph milestones and their significance for the research on the Roman roads in the south of the province of Dalmatia (east Herzegovina and west Montenegro). Milestones (miliarium) are the most reliable proof of the existence of the Roman roads, especially if they are in situ. They are historically highly valuable due to the fact that they are an exceptional testimony on the existence of the Roman roads in the eastern areas of Herzegovina and western areas of Montenegro. The road network in the south of the province of Dalmatia presented integral part of military, political and economic plans of the Romans. These roads connected the coastline with the available continental passes through the massive Dinarides. A significant numbers of epigraph and non-epigraph milestones that were found testify on the existence of the Roman road which intersected east Herzegovina and west Montenegro going from west towards east and from south to north (Narona-Dyrrachium, Narona-Sarajevo, Epidaurum-Anderba). The found milestones and epigraph inscriptions contributed to determining assumed road routes in the south of Dalmatia and the approximate date of their construction. That is why it is thought that Narona-Dyrrachium, Narona-Sarajevo, Epidaurum-Anderba roads were started by the Dalmatian appointed consul suffectus Publius Cornelius Dolabella (from 14 to 20) and that they were finished during the rule of Claudius (41–54). Additional repairs of these roads were done in the 3 and 4 centuries and the milestones found in the area of Konjic (seven of them), Nevesinje (two), Trebinje (three) and Nikšić (two) testify about that. They help us determine the approximate date of the road construction.
Osvrt na arhitektonski kompleks na Mogorjelu kao problem historiografije XIX, XX i XXI stoljeća / A review of the Mogorjelo architectural complex as the historiographical problem of the 19th, 20th and 21st centuries
Authors: Veletovac Edin 
Published: November 2021

Ever since it has been mentioned for the first time in the 19 century, the site of Mogorjelo has sparked the interest of the scholarship. Much of what we know today about this architectural complex is owed to Carl Patch who conducted a systematic archaeological research at this site from 1899 to 1903. Patch believed that the discovered remains of the complex, in fact, represent a former Roman camp or a castrum, one link in the system of Roman forts between the rivers Krka and Neretva. He dated this camp to the period of the 1 st th century which was restored in the second half of the 3 rd century after being destroyed at the beginning of the 2 century. Scholars such as Bojanovski, Anthes, Swoboda, Duval and Špehar agreed with Patch that Mogorjelo was a military camp, but they rejected the 1 century as its date. The second group of scholars rejected this view and believe that this site was the center of a large agricultural estate with supporting facilities. When it comes to construction phases and dating, the majority of scholars agree that the remains, visible today in Mogorjelo, belong to the Late Antiquity period, more specifically the 4 century. However, their opinions differ in case of construction. Thus, some scholars, such as Basler and Vetters, believe that the first construction phase can be dated to the 1 th century, whereas others believe that this phase took place somewhat later. st Although it has been more than one century since the discovery of Mogorjelo, we can assume that two basic requirements are necessary for obtaining a definite answer regarding its character and construction phases. The first requirement is the analysis and publication of over 150 crates of materials that Carl Patsch has dug out during the systematic research between 1899 and 1903. This material was sent to the National Museum in Sarajevo where it has been sitting in its depot ever since. An important drawback in the study of Mogorjelo is the lack of access to the logs compiled by Carl Patch, as well as his drawings, photographs and plans prepared from 1899 to 1903 that are being kept today in Südost-Institut in Munich. The unavailability of his excavation insights, remarks and notes represent a gap for all researchers who have dealt with Mogorjelo. Thus the second requirement is the publication of Patch’s materials which would enable all interested researchers to access his work and study this site.

A citrate pyrolysis technique is a unique route to prepare reactive precursor mixtures through an ignition process of concentrated aqueous solution. This procedure enables to synthesize highly homogeneous and fine powders for functional materials. The double-chain based superconductor Pr2Ba4Cu7O15−δ and double perovskite photocatalytic semiconductor Ba2Tb(Bi,Sb)O6 were synthesized by using the citrate pyrolysis technique. For the present sample with a reduction treatment for 72 h, a sharp superconducting transition appeared at an onset temperature Tc,on=26 K accompanied by a zero-resistance state at Tc,zero=22 K. The superconducting volume fraction estimated from the magnetization measurement showed an excellent value of ∼58%. Both reduction treatment in a vacuum and subsequent quenching procedure are needed to realize higher superconductivity due to further oxygen defects. The polycrystalline samples for Ba2Tb(Bi1−x,Sbx)O6 (x=0 and 0.5) were formed in the monoclinic and cubic crystal structures. We conducted the gaseous 2-propanol (IPA) and methylene blue (MB) degradation experiments under a visible light irradiation, to evaluate photocatalytic activities of the powder samples. For the Sb50% substituted sample, the highest performance of MB degradation was observed. The effect of Sb-substitution on the photocatalytic degradation of MB is in direct contrast to that on the IPA decomposition under visible light irradiation. The enhanced photocatalytic properties in the citrate samples are attributed to their morphology, where fine particles are homogeneously distributed with a submicron order.

Published: November 2021

Treatment of acute postoperative pain is an essential part of perioperative care and if left untreated could complicate the healing period. Ketamine blocks nociceptive pain and pain arising from inflammation. Therefore, it is potentially beneficial in the postoperative period. After systematic review using “MEDLINE/PubMed (NLM)” database, we analyzed 18 studies published during 2011–2020 and found that 0.5 mg/kg/h ketamine bolus and 0.1–0.25 mg/kg/h ketamine infusion to be the most effective dose to alleviate postoperative acute pain. Ketamine, when compared with a placebo, did not have any impact on patients’ satisfaction with postoperative pain management and overall well-being. Only three studies revealed more frequent adverse reactions to ketamine after surgery suggesting that ketamine did not have any impact on patients’ postoperational rehabilitation. So, it is the option to recommend low-dose ketamine to be part of multimodal analgesia in acute severe postoperative pain treatment. It can be used in both opioid-dependent and opioid-tolerant patients. Ketamine bolus should be ≤0.35 mg/kg and infusion ≤1 mg/kg/h. One should avoid the use of ketamine in pregnant women, people with cardiovascular diseases, acute psychosis, impaired liver function, increased intracranial, and intraocular pressure. Intranasal ketamine may be considered for children during procedures outside of the operation room.

Published: November 2021

In an effort to overhaul and stabilise the banking sector, the Bank of Ghana revoked the licences of nine Ghanaian banks and one was downgraded to savings and loans institution which later folded up summing up to ten banks. This paper investigated the effects of the collapse banks on customers. Using a quantitative approach, the study revealed that the collapse of the banks had major impacts on customers including loss of capital, disincentive to do further savings, inability to pay creditors and a general decline in the capacity to handle needs including educational plans. In addition, the study established that the most affected customer category was current account holders. Among others, the study recommends that the Bank of Ghana should be cautious in handing distressed banks, and also encourage self-regulation among banks mainly through the Bankers’ association. It is also recommended that over ambitious branch network expansions should be scrutinized regularly by the Central Bank. As part of the governance framework, universal banks should also put in place mechanisms to monitor and sanction both internal and external auditors when their works fall below expectations.

Determinants of the Digital Divide among French Higher Education Teachers
Authors: Dahmani Mounir 
Published: November 2021

The widespread use of technology in daily life, and particularly in education in higher education institutions has devoted growing attention to the nature of ICT usages by Higher Education Teachers which has seen as an increasingly important factor for the successful integration of these technologies. This study aims to analyze the determining factors of the various uses of ICT by teachers in the university environment and to characterize their variety and intensity. For this end, we conducted a survey of a sample of 2,079 teachers from public universities in France. Our approach consisted in measuring the intensity of use of ICT in academia in order to appreciate the resulting digital divides between different groups of teachers. Multinomial logistic regression shows that the differences in the use of ICT are linked to the differences in initial digital skills between teachers. Furthermore, the training in ICT, age, gender and social context appear to have a manifold influence on ICT use. Our results clearly confirm the existence of digital divides, it prompts us to analyze more precisely the role of innovative users and that of first-time adopters when they appear to be actors involved in the diffusion of ICT within universities.
Electrically Tunable and Dramatically Enhanced Valley‐Polarized Emission of Monolayer WS2 at Room Temperature with Plasmonic Archimedes Spiral Nanostructures

Published: November 2021

AbstractMonolayer transition metal dichalcogenides (TMDs) have intrinsic valley degrees of freedom, making them appealing for exploiting valleytronic applications in information storage and processing. WS2 monolayer possesses two inequivalent valleys in the Brillouin zone, each valley coupling selectively with a circular polarization of light. The degree of valley polarization (DVP) under the excitation of circularly polarized light (CPL) is a parameter that determines the purity of valley polarized photoluminescence (PL) of monolayer WS2. Here efficient tailoring of valley‐polarized PL from monolayer WS2 at room temperature (RT) through surface plasmon–exciton interactions with plasmonic Archimedes spiral (PAS) nanostructures is reported. The DVP of WS2 at RT can be enhanced from <5% to 40% and 50% by using 2 turns (2T) and 4 turns (4T) of PAS, respectively. Further enhancement and control of excitonic valley polarization is demonstrated by electrostatically doping monolayer WS2. For CPL on WS2–2TPAS heterostructures, the 40% valley polarization is enhanced to 70% by modulating the carrier doping via a backgate, which may be attributed to the screening of momentum‐dependent long‐range electron–hole exchange interactions. The manifestation of electrically tunable valley‐polarized emission from WS2–PAS heterostructures presents a new strategy toward harnessing valley excitons for application in ultrathin valleytronic devices.
Near‐Unity Quantum Yield and Superior Stable Indium‐Doped CsPbBrxI3−x Perovskite Quantum Dots for Pure Red Light‐Emitting Diodes

Published: November 2021

AbstractAlthough all‐inorganic CsPbBrxI3−x perovskite quantum dots (PeQDs) are increasingly being used as a competitive material for pure red perovskite light‐emitting diodes (PeLEDs), they suffer from low luminescent ability and poor stability. In this study, an In3+‐doped CsPbBrxI3−x PeQD solution exhibits a near‐unity photoluminescence quantum yield (PLQY) of ≈99.8% and superior stability for more than half a year in atmosphere. As far as known, this is the highest PLQY and stability achieved for mixed halide PeQDs. In3+ ion doping not only reduces the surface vacancy defects because of the partial substitution of Pb2+ by the smaller radii of In3+ ions, but also enhances the formation energy of CsPbBrxI3−x PeQDs based on first‐principles calculations. Compared with pristine LEDs based on CsPbBrxI3−x, the pure red PeLEDs based on In3+‐doped CsPbBrxI3−x display a higher luminance of 423 cd m‐2, fivefold external quantum efficiency improvement up to 11.2%, and increased stability, providing a feasible and promising perspective for developing In3+‐doped CsPbBrxI3−x PeQDs applied efficiently in advanced light emitters for solid‐state lighting and displays.

AbstractBroadband white‐light emissions from low‐dimensional organic metal halides have received great attention for applications in energy‐efficient lighting and displays. However, the simultaneous realization of excellent color rendering indexes (CRIs) and high photoluminescence quantum efficiencies (PLQEs) in single‐component white‐light emitters remains a great challenge. Here, a unique 0D organic copper iodide (TPA)CuI2 (TPA = tetrapropylammonium) is developed, in which the edge‐sharing double trigonal planar [Cu2I4]2− dimers are surrounded by the organic cations TPA+, forming core/shell structures at the molecular level. These organic copper iodide single crystals exhibit a dual‐band white‐light emission covering the entire visible spectrum with a high PLQE of 84.4% and an excellent CRI of 91.3. In addition, (TPA)CuI2 nanocrystals are successfully synthesized and exhibit optical properties similar to those of the single‐crystal counterparts. Detailed photophysical studies reveal that the dual‐band emission originates from two self‐trapped emitting states in [Cu2I4]2− dimers, whose populations are strongly dependent on the temperature. The promising applications of (TPA)CuI2 as efficient and high CRI phosphors are demonstrated by a white‐light light‐emitting diode with a Commission Internationale de l'Eclairage coordinate of (0.31, 0.33).
A Radical Chain: Mononuclear “Gold Only” Photocatalysis

Published: November 2021

AbstractWe herein report an unprecedented reactivity of mononuclear gold catalysts acting as classical catalysts and at the same time as active partners in a radical chain mechanism, whereby gold is the only catalyst. The mechanism of the photo‐induced photosensitizer‐free “gold only”‐catalyzed cross coupling was studied in detail – experimentally and theoretically – based on the reaction between arylboronic acids and aryldiazonium salts. With a systematic set of stoichiometric experiments under various conditions and analytic methods, we could show that this mechanism is initiated by an aryl radical formed in the presence of blue LEDs and MeOH. This aryl radical enters the catalytic cycle to oxidize gold(I) to gold(II). Single electron transfer from gold(II) to the aryldiazonium salt then gives the cationic gold(III) complex by formation of a chain‐supporting aryl radical which then is enabled to start a new cycle by oxidation of gold(I) without the need for irradiation. At least every 432 cycles of the radical chain, a new chain‐initiating radical has to restart the radical chain. Eventually, the boronic acid is activated by the BF4− anion to transmetalate to gold(III), and reductive elimination delivers the desired product.magnified image

Published: November 2021

AbstractNanoparticles have been widely used in important biomedical applications such as imaging, drug delivery, and disease therapy, in which targeting toward specific proteins is often essential. However, current targeting strategies mainly rely on surface modification with bioligands, which not only often fail to provide desired properties but also remain challenging. Here an unprecedented approach is reported, called reverse microemulsion‐confined epitope‐oriented surface imprinting and cladding (ROSIC), for facile, versatile, and controllable engineering coreless and core/shell nanoparticles with tunable monodispersed size as well as specific targeting capability toward proteins and peptides. Via engineering coreless imprinted and cladded silica nanoparticles, the effectiveness and superiority over conventional imprinting of the proposed approach are first verified. The prepared nanoparticles exhibit both high specificity and high affinity. Using quantum dots, superparamagnetic nanoparticles, silver nanoparticles, and upconverting nanoparticles as a representative set of core substrates, a variety of imprinted and cladded single‐core/shell nanoparticles are then successfully prepared. Finally, using imprinted and cladded fluorescent nanoparticles as probes, in vitro targeted imaging of triple‐negative breast cancer (TNBC) cells and in vivo targeted imaging of TNBC‐bearing mice are achieved. This approach opens a new avenue to engineering of nanoparticles for targeting specific proteins, holding great prospects in biomedical applications.
Uncertainty quantification in machine learning and nonlinear least squares regression models
Authors: Zhan Ni , Kitchin John R. 
Published: November 2021

AbstractMachine learning (ML) models are valuable research tools for making accurate predictions. However, ML models often unreliably extrapolate outside their training data. The multiparameter delta method quantifies uncertainty for ML models (and generally for other nonlinear models) with parameters trained by least squares regression. The uncertainty measure requires the gradient of the model prediction and the Hessian of the loss function, both with respect to model parameters. Both the gradient and Hessian can be readily obtained from most ML software frameworks by automatic differentiation. We show examples of the uncertainty method in applications of molecular simulations and neural networks. We further show that the uncertainty measure is larger for input space regions that are not part of the training data. Therefore, this method can be used to identify extrapolation and to aid in selecting training data or assessing model reliability.

AbstractBipolar disorder (BD) is associated with a 20–30‐fold increased suicide risk compared to the general population. First‐degree relatives of BD patients show inflated rates of psychopathology including suicidal behaviors. As reliable biomarkers of suicide attempts (SA) are lacking, we examined associations between suicide‐related polygenic risk scores (PRSs)—a quantitative index of genomic risk—and variability in brain structures implicated in SA. Participants (n = 206; aged 12–30 years) were unrelated individuals of European ancestry and comprised three groups: 41 BD cases, 96 BD relatives (“high risk”), and 69 controls. Genotyping employed PsychArray, followed by imputation. Three PRSs were computed using genome‐wide association data for SA in BD (SA‐in‐BD), SA in major depressive disorder (SA‐in‐MDD) (Mullins et al., 2019, The American Journal of Psychiatry, 176(8), 651–660), and risky behavior (Karlsson Linnér et al., 2019, Nature Genetics, 51(2), 245–257). Structural magnetic resonance imaging processing employed FreeSurfer v5.3.0. General linear models were constructed using 32 regions‐of‐interest identified from suicide neuroimaging literature, with false‐discovery‐rate correction. SA‐in‐MDD and SA‐in‐BD PRSs negatively predicted parahippocampal thickness, with the latter association modified by group membership. SA‐in‐BD and Risky Behavior PRSs inversely predicted rostral and caudal anterior cingulate structure, respectively, with the latter effect driven by the “high risk” group. SA‐in‐MDD and SA‐in‐BD PRSs positively predicted cuneus structure, irrespective of group. This study demonstrated associations between PRSs for suicide‐related phenotypes and structural variability in brain regions implicated in SA. Future exploration of extended PRSs, in conjunction with a range of biological, phenotypic, environmental, and experiential data in high risk populations, may inform predictive models for suicidal behaviors.
