Simultaneous Disinfection and Organic Microcontaminant Removal by UVC-LED-Driven Advanced Oxidation Processes
Authors: Miralles-Cuevas Sara , De la Obra Irene , Gualda-Alonso Elizabeth , Soriano-Molina Paula , Casas López José L. , Sánchez Pérez José A.
Published: May 2021

This work presents the comparison of four advanced oxidation processes driven by UVC-LED radiation (278 nm—2 W/m2) for simultaneous bacteria inactivation (Escherichia coli—106 CFU/mL) and microcontaminant removal (imidacloprid—50 µg/L) in simulated wastewater secondary effluent. To this end, the activation of H2O2 and S2O82− as precursors of HO• and SO4•−, respectively, by UVC-LED and UVC-LED/Fe3+–NTA (ferric nitrilotriacetate at 0.1 mM) has been studied at different oxidant concentrations. For the purpose of comparison, conventional chlorination was used as the baseline along with bacterial regrowth 24 h after treatment. Disinfection was achieved within the first 30 min in all of the processes, mainly due to the bactericidal effect of UVC-LED radiation. UVC-LED/H2O2 did not substantially affect imidacloprid removal due to the low HO• generation by UVC irradiation at 278 nm, while more than 80% imidacloprid removal was achieved by the UVC-LED/S2O82−, UVC-LED/Fe3+–NTA/S2O82−, and UVC-LED/Fe3+–NTA/H2O2 processes. The most efficient concentration of both oxidants for the simultaneous disinfection and microcontaminant removal was 1.47 mM. Chlorination was the most effective treatment for bacterial inactivation without imidacloprid removal. These findings are relevant for scaling up UVC-LED photoreactors for tertiary wastewater treatment aimed at removing bacteria and microcontaminants.
Biogeochemistry of Mediterranean Wetlands: A Review about the Effects of Water-Level Fluctuations on Phosphorus Cycling and Greenhouse Gas Emissions
Authors: de Vicente Inmaculada
Published: May 2021

Although Mediterranean wetlands are characterized by extreme natural water level fluctuations in response to irregular precipitation patterns, global climate change is expected to amplify this pattern by shortening precipitation seasons and increasing the incidence of summer droughts in this area. As a consequence, a part of the lake sediment will be exposed to air-drying in dry years when the water table becomes low. This periodic sediment exposure to dry/wet cycles will likely affect biogeochemical processes. Unexpectedly, to date, few studies are focused on assessing the effects of water level fluctuations on the biogeochemistry of these ecosystems. In this review, we investigate the potential impacts of water level fluctuations on phosphorus dynamics and on greenhouse gases emissions in Mediterranean wetlands. Major drivers of global change, and specially water level fluctuations, will lead to the degradation of water quality in Mediterranean wetlands by increasing the availability of phosphorus concentration in the water column upon rewetting of dry sediment. CO2 fluxes are likely to be enhanced during desiccation, while inundation is likely to decrease cumulative CO2 emissions, as well as N2O emissions, although increasing CH4 emissions. However, there exists a complete gap of knowledge about the net effect of water level fluctuations induced by global change on greenhouse gases emission. Accordingly, further research is needed to assess whether the periodic exposure to dry–wet cycles, considering the extent and frequency of the cycles, will amplify the role of these especial ecosystems as a source of these gases and thereby act as a feedback mechanism for global warming. To conclude, it is pertinent to consider that a better understanding about the effect of water level fluctuations on the biogeochemistry of Mediterranean wetlands will help to predict how other freshwater ecosystems will respond.

Published: May 2021

Climate change significantly affects water supply availability due to changes in the magnitude and seasonality of runoff and severe drought events. In the case of Korea, despite a high water supply ratio, more populations have continued to suffer from restricted regional water supplies. Though Korea enacted the Long-Term Comprehensive Water Resources Plan, a field survey revealed that the regional government organizations limitedly utilized their drought-related data. These limitations present a need for a system that provides a more intuitive drought review, enabling a more prompt response. Thus, this study presents a rating curve for the available number of water intake days per flow, and reviews and calibrates the Soil and Water Assessment Tool (SWAT) model mediators, and found that the coefficient of determination, Nash–Sutcliffe efficiency (NSE), and percent bias (PBIAS) from 2007 to 2011 were at 0.92%, 0.84%, and 7.2%, respectively, which were “very good” levels. The flow recession curve was proposed after calculating the daily long-term flow and extracted the flow recession trends during days without precipitation. In addition, the SWAT model’s flow data enables the quantitative evaluations of the number of available water intake days without precipitation because of the high hit rate when comparing the available number of water intake days with the limited water supply period near the study watershed. Thus, this study can improve drought response and water resource management plans.

Published: May 2021

Many countries are confronted with a striking problem of morbidity of fluorosis that appears because of an increased concentration of fluorides in drinking water. The objective of this study is to explore opportunities for removal of fluoride from aqueous solutions using cheap and easily accessible adsorbents, such as exhaustive coffee grounds and iron sludge and to establish the efficiency of fluoride removal. Twelve doses (1, 2, 3, 4, 5, 6, 10, 20, 30, 40, 50 and 60 g/L) of adsorbents were used and five durations of the sorption process (30, 60, 90, 120 and 150 min). The results showed that the most optimum dose of iron sludge for 3 mg/L of fluoride removal was 30 g/L and the contact time was 30 min, the efficiency of fluoride removal achieved 62.92%; the most optimum dose of exhausted coffee grounds was 60 g/L with the most optimum contact time of 60 min; at a dose of 50 g/L with contact time of 90 min, the efficiency of fluoride removal achieved 56.67%. Findings demonstrate that adsorbents have potential applicability in fluoride removal up to the permissible norms.

This research work reports the magnetic adsorption of fluoride from drinking water through silica-coated Fe3O4 nanoparticles. Chemical precipitation and wet impregnation methods were employed to synthesize the magnetic nanomaterials. Moreover, the synthesized nanomaterials were characterized for physicochemical properties through scanning electron microscopy, Fourier-transform infrared spectroscopy, and X-ray powder diffraction. Screening studies were conducted to select the best iron oxide loading (0.0–1.5 wt%) and calcination temperature (300–500 °C). The best selected nanomaterial (0.5Fe-Si-500) showed a homogenous FeO distribution with a 23.79 nm crystallite size. Moreover, the optimized reaction parameters were: 10 min of contact time, 0.03 g L−1 adsorbent dose, and 10 mg L−1 fluoride (F−) concentration. Adsorption data were fitted to the Langmuir and Freundlich isotherm models. The Qm and KF (the maximum adsorption capacities) values were 5.5991 mg g−1 and 1.869 L g−1 respectively. Furthermore, accelerated adsorption with shorter contact times and high adsorption capacity at working pH was among the outcomes of this research work.
The Phenotypic Difference of IgA Nephropathy and its Race/Gender-dependent Molecular Mechanisms
Authors: Suzuki Yusuke , Monteiro Renato C. , Coppo Rosanna , Suzuki Hitoshi
Published: May 2021

IgA nephropathy (IgAn), defined by the pre dominant de position of IgA in the glomerular mesangium, is the most common form of GN throughout the world. However, its incidence, sex distribution, clinical presentation, and progression and pathogenic initiating factors are largely variable and do not fit such a simple definition. To assess the heterogeneity of this disease, we recently conducted a clinical survey on the presentation and clinical management of patients with IgAn in Europe and Japan. This clinical survey highlights similarities and differences in patients from different cont inents. The survey revealed obvious differences between nations in the frequency of gastrointestinal complications, including inflammatory bowel diseases (IBD) and celiac disease, which were more frequent in European patients. Such findings are compatible with susceptibility loci related to intestinal immunity and IBD in recent genome wide association studies (GWAS) on IgAn. However, most of the molecules in these mucosal-related loci fulfill the immunologic function not only of gut-associated lymphoid tissue (GALT), but also nasopharyngeal/bronchial-associated lymphoid tissues (NALT/BALT). Indeed, a similar frequency of macrohematuria coinciding with upper respiratory infection, a hallmark manifestation of this disease, was found in the survey, emphasizing the pathogenic roles of these molecules in the NALT/BALT of patients with IgAn. Recent experimental and clinical studies including GWAS on multiple common infections and IBD indicate immune crosstalk between GALT and NALT/BALT, and some related mediators, such as TNF superfamily ligands (APRIL/BAFF). This review explains the epidemiologic heterogeneity of this disease with the clinical survey, and discusses race and sex-dependent molecular mechanisms.

Published: May 2021

Despite the development and great progress in the field of space biology, the astronauts are still facing many challenges in space. The space environment in which astronauts stay includes microgravity, noise, circadian rhythms disorder, and confinement, which has deep effect both on the physiology and psychology of astronauts. It was reported that long-term flight could cause the astronauts’ anxiety and depression. However, the underlying mechanism is not yet fully understood. Therefore, in the present study, the rat tail suspension model with noise, circadian rhythms, and confinement was employed to simulate complex space environment. We found that the rats exhibited the depressive-like behavior by the sucrose preference, forced swimming, and open-field tests. The membrane proteome of the rat hippocampus was investigated by “SWATH quantitation” technology both in control and simulated complex space environment (SCSE) groups. Out of 4520 quantified proteins, 244 differentially expressed membrane proteins were obtained between the SCSE and control rats, which were functionally enriched in a series of biological processes, such as translation, protein phosphorylation, brain development, endocytosis, nervous system development, axonogenesis, and vesicle-mediated transport. We found a reduction level of neurexin-2, the light, medium, heavy polypeptide of neurofilament, rab 18, synaptogyrin 1, and syntaxin-1A and an increase level of neuroligin-1, munc18, snapin, synaptotagmin XII, complexin-1, etc., which may play a key part in the development of depression. Furthermore, GSK-3
β
protein was upregulated in mass spectrometry, which was further validated by western blotting. The results of the study do the favor in designing the effective countermeasures for the astronauts in the future long-term spaceflight.

Published: May 2021

Halide perovskites with low-dimensionalities (2D or quasi-2D) have demonstrated outstanding stabilities compared to their 3D counterparts. Nevertheless, poor charge-transporting abilities of organic components in 2D perovskites lead to relatively low power conversion efficiency (PCE) and thus limit their applications in photovoltaics. Here, we report a novel hole-transporting low-dimensional (HT2D) perovskite, which can form a hole-transporting channel on the top surface of 3D perovskite due to self-assembly effects of metal halide frameworks. This HT2D perovskite can significantly reduce interface trap densities and enhance hole-extracting abilities of a heterojunction region between the 3D perovskite and hole-transporting layer. Furthermore, the posttreatment by HT2D can also reduce the crystal defects of perovskite and improve film morphology. As a result, perovskite solar cells (PSCs) can effectively suppress nonradiative recombination, leading to an increasement on photovoltage to >1.20 V and thus achieving >20% power conversion efficiency and >500 h continuous illumination stability. This work provides a pathway to overcome charge-transporting limitations in low-dimensional perovskites and delivers significant enhancements on performance of PSCs.

Instructing Reading Comprehension Strategies: Effects on EFL Learners’ Self-Efficacy in Reading
Authors: Valizadeh Mohammadreza
Published: May 2021

This experimental study, using pretest-intervention-posttest design, investigated whether or not teaching English as a foreign language (EFL) learners to use comprehension strategies when they read English passages, increases their self-efficacy in reading. The participants were 55 EFL learners in Turkey who were at lower-intermediate level based on the results of the Oxford Quick Placement Test. Data were gathered via a Reading Self-Efficacy Questionnaire. The whole treatment/control period lasted for 11 weeks during a reading course. The experimental group (n = 28) received instruction in reading comprehension strategies (i.e., previewing, scanning for details, skimming, identifying the topic and main idea, finding supporting details, making inferences, understanding the author’s purpose, making predictions, dealing with unfamiliar words, using context clues, and summarizing). The control group (n = 27) received instruction by traditional teaching methods (i.e., reading, paraphrasing, translating, and answering the exercises).The results of the Mann-Whitney U Test indicated that instruction in English reading comprehension strategies had a positive effect on EFL learners in terms of increasing their self-efficacy in reading.

Published: May 2021

This study aimed at finding self-regulatory capacity and habits of 3 learners with differing proficiency levelsat Translation and Interpretation department of a State university in Turkey. This is a multiple case study and longitudinal in nature in which the process of vocabulary learning was observed in three subsequent school terms. The participants were chosen according to several exam grades from prep classes and out of 15 voluntary participants; three were chosen and were named as a good starter in more improving group, average starter in less improving group and a steady one in decreasing group in terms of their grades. Data collection tools included three narrations as retrospective data, six interviews and six self-reports. The collected data was analyzed according to a checklist which was modified from a scale called “Self-regulatory Capacity for Vocabulary Acquisition (SRC voc)” (Tseng et al 98). The data was coded under the subheadings of that checklist. It was concluded after the analysis that self-regulation was an important indicator and predictor for success in vocabulary acquisition. The good starter and average starter student was able to overcome some negative feelings or habits during his/her vocabulary learning process; however, the steady one was unable to create an effective balance between good and bad feelings and seemed to feel pessimistic and unsuccessful although she tried hard. Some causal attributions behind these learners’ positive or negative attitudes or feelings towards vocabulary learning also seemed to play a significant role in their self-regulatory capacities in vocabulary acquisition.

The coral reef ecosystem has been continuously degraded in various parts of Indonesia, including the Anambas Islands. This research aimed to discover the content of Potassium Cyanide (KCN) accumulated on corals and the effect on indicator fishes abundance in the Anambas Islands. This research was conducted at 25 observation stations in the Anambas Islands National Marine Protected Area. The potassium cyanide (KCN) content was tested with the principle of titration and distillation. The coral samples used ranged from 10-20 g diluted in 100-200 ml distilled water. The method used to determine the abundance of indicator fish was underwater visual census or UVC, which recorded fish in every station. This research recorded 307 fish individuals from 14 species of the Chaetodontidae family. Potassium Cyanide's content on corals was high ranging from 0,009-0,032 mg/L with an average 0,0205 mg/L. We concluded that there was a negative correlation between the content of Potassium Cyanide  (KCN) on corals and indicator fishes abundance, which means the higher the Potassium Cyanide content (KCN) is on corals, the lower the indicator fishes abundance will point out.

Authors: Rao Y Srinivas , Chheda Hemal , Surendra Ch , Vijayasekhar M V , Varaprasad K Satya
Published: May 2021

BACKGROUND : Colloid cysts are one of the rare brain tumours and are mostly located in the anterosuperior portion of the third ventricle,
between the fornix and surround of Foramen of Monroe.
OBJECTIVES:
Ÿ 1.To review the demographic information & analyse clinical manifestations of patients presenting with colloid cyst of third ventricle.
Ÿ 2.To analyze the advantages and disadvantages of various surgical approaches
Ÿ 3.To assess the surgical outcome in colloid cyst patients operated by any method.
MATERIALS AND METHODS: A retrospective study was performed on 16 patients who presented with a colloid cyst and underwent surgery at
the Department of Neurosurgery, King George Hospital, Andhra Medical College between 2013-2018. They were evaluated based on clinical
ndings and imaging features, surgical approaches used for resection and their outcomes.
RESULTS: Sixteen cases of colloid cyst of the third ventricle were operated upon between 2013-2018. There were seven male and nine female
patients with their ages varying between 9 and 62 years old. Nine patients were operated on by using a transcortical trans-ventricular approach, four
using the anterior trans-callosal approach and, three patients by using an endoscopic approach. In all patients, complete excision of the lesions was
achieved.
CONCLUSION: Colloid cysts, though benign, present surgical challenges because of its deep midline location. Complete excision of the colloid
cyst carries an excellent prognosis. Surgery is a safe and effective treatment option for this benign lesion.

Published: May 2021

Introduction: Serum ferritin is a marker for iron stores and is an acute phase reactant. Its role in pathogenesis of Diabetes is suggested by
improvement in insulin sensitivity and insulin secretion with frequent blood donation and decreased iron stores. Objective of the present study is to
determine correlation of serum ferritin with glycemic control.
Material and Methods: This analytical cross sectional study was conducted at a tertiary care centre of southern India, including 50 diabetic
patients with good glycemic control and 50 patients with poor glycemic control.
Results: Mean serum ferritin level of diabetics was signicantly lower in diabetics with good glycemic control (119.07±58.99 ng/ml) as compared
to those with poor glycemic control (331.11±140.69 ng/ml). Serum ferritin showed strong positive correlation (p <0.001)with the duration of
diabetes (r = 0.651) and HbA1C (r = 0.828).
Conclusion: Serum ferritin levels were higher in diabetic individuals with poor glycemic control and serum ferrition showed strong positive
correlation with glycemic control (HbA1C). Serum ferritin may be used as marker for screening poor glycemic control and patients at high risk of
developing complications.

Adiscal cyst is a rare lesion that causes low back pain and radiculopathy of the lower extremities. There are several reports of discal cysts occurring
after surgery, but data are limited on their occurrence after percutaneous endoscopic discectomy (PED). A21-year-old man with disc herniation at
the L4-L5 disc level underwent PED via a transforaminal approach. The immediate postoperative course was uneventful and his symptoms were
relieved. Six weeks after surgery, low back pain and mild pain in the left thigh recurred. Magnetic resonance imaging (MRI) revealed a cystic lesion
adjacent to the left side of the L4-L5 intervertebral disc. Conservative treatment was ineffective, so we reoperated using PED with the same
approach. Pain improved and MRI revealed disappearance of the cystic lesion. When symptoms relapse after PED, it is necessary to consider the
occurrence of a cyst. Endoscopic Minimally Invasive Surgery

Authors: Lilly R.Beaula , Banu V.K.M.
Published: May 2021

The emergence of Vancomycin resistant enterococci (VRE) has posed serious threats to the community because they exhibit multiple drug resistance, thus limiting the therapeutic options for the clinicians. As Vancomycin resistant enterococci (VRE) also have ampicillin resistance and high level aminoglycoside resistance, they are the most difcult to treat. The therapeutic options are limited by elimination of the synergy between aminoglycoside and the beta lactum drugs which is the treatment of choice for enterococcal infections which is of great concern. More antibiotic resistance makes these pathogens excellent survivors in hospital environment and cause nosocomial infections. Atotal of 142 enterococcal isolates from various clinical samples were identied to their species level and subjected to antimicrobial susceptibility testing to various antibiotics. Initial screening for Vancomycin resistance was done using the Vancomycin Screen Agar and the isolates showing resistance were subjected to Vancomycin and Teicoplanin MIC and later these isolates showing resistance were conrmed by genotypic methods for Vancomycin resistant genes.Total VRE isolates as per Vancomycin MIC value were 19 and the prevalence rate was 13.3% (19/142).In PCR assay, a total of 16 isolates including 13 E.faecium and 3 E.faecalis were found to be of Van B genotype and the remaining 3 isolates including 2 E.faecium and 1 E.faecalis were found to be of Van A genotype. In this study, the prevalence of Vancomycin resistance in Enterococcal species is 13.3% as per vancomycin MIC by Micro broth dilution technique. The phenotypic detection of Vancomycin resistance by MIC of Vancomycin and Teicoplanin correlates with the genotypic method of detection of Vancomycin resistant genes (VanA, VanB).

Published: May 2021

L’articolo si propone di verificare sinteticamente il rapporto tra il recente sviluppo delle biblioteche digitali e la ricerca umanistica, valorizzando il punto di vista dell’utente finale, lo studioso. È stata presa ad esempio una ricerca nell’ambito della storia della miniatura. Essa può oggi giovarsi di numerosi database dedicati alle collezioni digitali di manoscritti miniati medievali, e servirsi di avanzate funzioni di ricerca iconografica. La digitalizzazione ha permesso di superare la fase in cui l’alternativa alla consultazione diretta del manoscritto di pregio era il microfilm. La qualità delle immagini digitali permette spesso uno studio più agevole ed efficace di quello offerto dalla visione diretta dell’originale.

Lo sviluppo delle risorse digitali e della ricerca scientifica online sta creando nuovi requisiti di interoperabilità e di vocabolario comune. Il libro manoscritto è direttamente interessato da questa sfida, a causa dell’eterogeneità dei sistemi di vocabolario e delle variazioni nell’espressione delle segnature: non solo lo stesso manoscritto è stato designato in diversi modi diversi nel corso della sua storia, in quanto è stato spostato e il patrimonio è stato riclassificato, ma è ancora oggi spesso designato in modi diversi. Queste ambiguità rendono difficile l’aggregazione delle informazioni su Internet. Per superare questi problemi, il Consorzio ISMI, costituito nel novembre 2018, propone di creare un identificatore numerico o alfanumerico universale per l’oggetto manoscritto (e non per la sua riproduzione digitale o la sua registrazione in un catalogo) sulla base di un accordo internazionale. I vocabolari così sviluppati, che si rivolgeranno inizialmente ai manoscritti medievali, saranno basati su Open Linked Data.

e-Leo. Archivio digitale di storia della tecnica e della scienza è stato sviluppato e realizzato dalla Biblioteca Leonardiana di Vinci, centro di ricerca e documentazione per gli studi leonardiani, e prende le mosse dalla volontà di offrire uno strumento efficace di studio e consultazione delle opere di Leonardo da Vinci, oltre che di valorizzazione della collezione. L’esperienza è radicata nella tipologia molto specifica del fondo speciale della biblioteca, che possiede il corpus di tutte le opere di Leonardo da Vinci pubblicate a partire dalla prima edizione del Trattato della pittura del 1651. A partire dal 2007, e-Leo rappresenta l’unica pubblicazione online quasi integrale del lascito leonardiano. Un’importante modifica della struttura interna del codice ed un aggiornamento della grafica nel 2019 hanno reso lo strumento ulteriormente performante e aperto a ulteriori potenziali sviluppi, oltre ad averne consentita la consultazione anche da smartphone e tablet. I dati, rappresentati da testi e disegni, sono ricercabili per mezzo di metodi di ricerca e indicizzazione di contenuti testuali, delle componenti grafiche del documento, di glossari tematici: un apparato che propone un modello integrato e più ampio per il trattamento, secondo criteri affini, di testi manoscritti di argomento tecnico-scientifico del tardo medioevo e del rinascimento.

Questi passi hanno consentito l’accesso ad un patrimonio informativo in continua crescita e sempre più costituito da risorse digitali. Contestualmente si è attuato un profondo cambiamento delle relazioni tra l’utente e la biblioteca. La crescita degli accessi ai materiali e del loro utilizzo sono prova dell’aumento costante dei flussi informativi consentiti dalla Biblioteca Digitale e come tali recepiti dall’utenza. In questa situazione le biblioteche sono state interpreti in prima linea della mutazione in atto nelle modalità di trasmissione della conoscenza andando a studiare le nuove realtà e progettando e realizzando i servizi innovativi da queste resi attuabili. Non è possibile oggi prevedere quali saranno gli sviluppi della biblioteca e della Biblioteca Digitale nei prossimi anni ma resta comunque necessario rispondere alle sempre nuove esigenze dell’utenza, in una continua e tempestiva navigazione a vista.
Non solo ebook: la biblioteca digitale per l’e-learning
Authors: Tammaro Anna Maria
Published: May 2021

La biblioteca digitale ed i sistemi e-learning sono entrambi sistemi socio tecnologici la cui visione ha avuto origine dalla scienza cognitiva. Malgrado ciò, attualmente esiste un gap tra le comunità delle biblioteche digitali e dell’e-learning. Attraverso un'analisi sistematica della letteratura e della documentazione vengono descritti gli approcci teorici e le buone pratiche della convergenza tra biblioteche digitali ed e-learning. È necessaria una migliore comprensione dei bisogni formativi - non come sono percepiti dalla comunità delle biblioteche digitali ma come sono sperimentati nel campo dalle comunità di apprendimento - questo contribuirà a colmare il divario tra le due comunità delle biblioteche digitali e dell’e-learning. Inoltre, offrire risorse educative aperte sarà un passo strategico utile per rafforzare il coinvolgimento delle biblioteche digitali nell’apprendimento. Portando nuove applicazioni nel campo dell'insegnamento, le biblioteche digitali potrebbero agire come innovatrici nel campo dell'apprendimento.

Published: May 2021

inDICEs è un progetto di ricerca e innovazione finanziato dalla Commissione Europea nell'ambito del programma Horizon 2020, e coordinato dall'ICCU. La ricerca condotta da inDICEs permetterà di sviluppare una metodologia scientifica per misurare e valutare l’impatto economico della digitalizzazione del patrimonio culturale, analizzando le modalità di accesso ai beni e ai servizi culturali in Europa. A partire da questo, il progetto elaborerà delle raccomandazioni rivolte ai responsabili del settore dei beni culturali e delle industrie culturali e creative, per fornire loro strumenti utili ad affrontare le sfide poste dall'avvento del mercato unico digitale al fine di far prosperare e diffondere la cultura europea. Infine, il progetto svilupperà una piattaforma partecipativa e un sistema di autovalutazione, utile agli istituti culturali per migliorare il proprio posizionamento strategico nel mercato unico digitale, favorendone perciò la trasformazione digitale.

Deep Reinforcement Learning for Radio Resource Allocation and Management in Next Generation Heterogeneous Wireless Networks: A Survey
Authors: Alwarafy Abdulmalik , Abdallah Mohamed , Ciftler Bekir Sait , Al-Fuqaha Ala , Hamdi Mounir
Published: May 2021

Next generation wireless networks are expected to be extremely complex due to their massive heterogeneity in terms of the types of network architectures they incorporate, the types and numbers of smart IoT devices they serve, and the types of emerging applications they support. In such large-scale and heterogeneous networks (HetNets), radio resource allocation and management (RRAM) becomes one of the major challenges encountered during system design and deployment. In this context, emerging Deep Reinforcement Learning (DRL) techniques are expected to be one of the main enabling technologies to address the RRAM in future wireless HetNets. In this paper, we conduct a systematic in-depth, and comprehensive survey of the applications of DRL techniques in RRAM for next generation wireless networks. Towards this, we first overview the existing traditional RRAM methods and identify their limitations that motivate the use of DRL techniques in RRAM. Then, we provide a comprehensive review of the most widely used DRL algorithms to address RRAM problems, including the value- and policy-based algorithms. The advantages, limitations, and use-cases for each algorithm are provided. We then conduct a comprehensive and in-depth literature review and classify existing related works based on both the radio resources they are addressing and the type of wireless networks they are investigating. To this end, we carefully identify the types of DRL algorithms utilized in each related work, the elements of these algorithms, and the main findings of each related work. Finally, we highlight important open challenges and provide insights into several future research directions in the context of DRL-based RRAM. This survey is intentionally designed to guide and stimulate more research endeavors towards building efficient and fine-grained DRL-based RRAM schemes for future wireless networks.
