Authors: Baharuddin Fikri , Tjahyanto Aris
Published: April 2022

Classification using machine learning is an alternative that is widely used to classify data. There are various classification methods or also known as machine learning classification algorithms that can be used. However, to get the best classification results, we need a classifier that fits the dataset type to provide the best classification performance. In addition, the quality and quantity of data contained in a dataset also has an influence on the classification performance. In this study, several attempts were made to improve the classification performance of the dataset of Indonesian language exam questions at the elementary school level based on the category of difficulty level. The efforts made consist of improving the quality of the dataset and using the StringToWordVector filter algorithm to manage textual data, as well as the use of several classification algorithms such as the nave Bayes algorithm, Random Forest, and REPTree. Classification is done by using WEKA Tools. The results of the experiments carried out showed the highest performance increase of 15% after improving the quality of the dataset and using the right classification method.

Predicting Countries Credit Ratings with Institutional Performance
Authors: Elidrissi Anas Moussaid
Published: April 2022

In order to widen the vision and to visualize the impact of the institutions on not only economic growth as traditionally used but also on the Credit Ratings of countries, this experiment studies the correlation between these two attributes. In this paper, I show how we can find the relationship between the credit ratings of countries and the performance of their institutions. In this study, I used a data set of countries and indicators of their performance on institutional indicators, such as property rights, judicial effectiveness ...etc. And I conclude at the end that there is a strong correlation between an effective institution and a higher rating in credits report that is done by the major firms in this area. Also, I mention the limitation of this experiment in the matter of credibility.
How a Buddha Acts
Authors: Maithani Mukund
Published: April 2022

Buddhist philosophers generally hold that concepts like “I” and “me,” while useful in everyday life, are ultimately meaningless. Under this view, there would be no “agents” because it is meaningless to say “I did so and so....” How do we explain the occurrence of actions without referring to agents? I argue that Cappelen and Dever’s Action Inventory Model (AIM) is a useful resource for developing a Buddhist theory of action. In response to an objection that AIM cannot explain a buddha’s action, I show that a slightly tweaked version of AIM succeeds in explaining how a buddha acts.
Why Does God Need Freedom?
Authors: Silverpen Klayton
Published: April 2022

God is often portrayed as being omnipotent, omniscient, and omnibenevolent. Many worry that these traits make it so that God cannot possess free will. However, very little is said about why a God without freedom would be an issue. I argue that God does not need the kind of freedom we usually care about. I make a case that free will is important to us because it allows us to assign blame and praise to others. From here, I argue that being able to blame God is unimportant, and that God can still be praised even without free will.
L’Inghilterra nelle poesie ‘politiche’ di Vincenzo Monti. Appunti per un’analisi stilistica
Authors: Penso Andrea
Published: April 2022

L’articolo ambisce a investigare la percezione che Vincenzo Monti ebbe dell’Inghilterra nella sua poesia ‘politica.’ Piuttosto trascurata, anche a fronte di un sempre crescente peso culturale e politico, nella corrispondenza privata di Monti, l’Inghilterra trova invece uno spazio non piccolo nella produzione in versi del poeta. Un dettagliato close-reading delle opere più rilevanti svela infatti come le idee di Monti si siano tradotte in una serie di stilemi ed espedienti stilistici tipizzata, abbondantemente riusata e quindi facilmente riconoscibile. Questa standardizzazione operata da Monti concorre a dipingere ritratti ben precisi dell’Inghilterra in funzione dei propri scopi di poeta d’occasione, confermando al tempo stesso non una reale curiosità o meditazione sulla nazione come era stato per molti suoi contemporanei, ma piuttosto un interesse ‘strumentale,’ dato specialmente dalla necessità di includerla sulla scena di vivide rappresentazioni messe al servizio della propria poesia encomiastica, frutto di occasioni ‘ufficiali.’ Infine, l’indagine serve anche a comprendere alcune caratteristiche della poesia ‘politica’ di Monti: l’approfondimento del caso-studio in questione permette infatti di decifrare l’ecletticità del poeta per comprenderne alcune delle ragioni e manifestazioni.

Published: April 2022

Among patients with chronic lymphocytic leukemia (CLL) with deletion 17p (del[17p]), evidence from clinical trials for the effectiveness of single-agent ibrutinib as first-line therapy is limited. This retrospective analysis compared real-world clinical outcomes among patients with CLL, with and without del(17p), treated with first-line ibrutinib monotherapy. Overall survival, time to next treatment, time to treatment discontinuation, and reasons for ibrutinib discontinuation were evaluated. Using data from a real-world database, patients included were aged ≥18 years, had been diagnosed with CLL between January 1, 2011 and December 31, 2019, had undergone cytogenetic testing, and had received first-line ibrutinib monotherapy. A total of 1,069 patients were included in the analysis (62.7% male; median age 69 years); 23.8% (n=254) had del(17p). The median overall survival was significantly shorter in patients with del(17p) than in patients without (57.7 months vs. not reached; P=0.0006). Similar results were observed for median time to next treatment (49.4 months vs. not reached, P=0.0330). The median time to treatment discontinuation was non-significantly shorter in the group of patients with del(17p) (32.5 months vs. 42.9 months, P=0.3370). Results of an adjusted Cox proportional hazards model showed that the group with del(17p) was at significantly higher risk of death than was the group without del(17p) (hazard ratio=1.70, P=0.0031). Event rates for switching to new treatment and discontinuation were higher but not statistically significantly so. The most common reason for discontinuing ibrutinib treatment in both groups was toxicity, but discontinuation due to progression was significantly more frequent among patients with del(17p) (20% vs. 6%; P<0.0001). This study identifies an unmet need for more effective first-line therapeutic options in patients with CLL/small lymphocytic lymphoma and del(17p), despite the advent of ibrutinib.

Mesoeconomic Modeling of Structural Shifts of the Us Industry: Industry and Spatial Components
Authors: Minat Valerij N.
Published: April 2022

The evolution of socio-economic relations, studied in the dynamics of the development of such a phenomenon as structural changes in industry caused by the diffusion of knowledge-intensive technologies of a convergent type, is most consistently revealed within the framework of the mesoeconomic production system of the country level, through appropriate modeling of characteristic objects and processes. The mesoeconomic modeling of the industrial sector of the American economy, which entered a qualitatively new period of reindustrial development a decade ago, seems relevant. The aim of this study is to use elements and modeling systems that meet the requirements of sectoral and regional mesoeconomics to assess the structural shifts that took place in the US industry in the period 2011–2020 under the influence of convergent technologies. To solve this problem, the DEA-method is used, developed and tested by the American scientists and is aimed at calculating the convergent resonance index and the indicator of the comparative efficiency of the objects under study. Based on the results of constructing models of the technological efficiency of the US industry in space-time, oriented to the input and output parameters, an assessment of the structural shifts of the American industry, both sectoral and spatial-regional components of the US mesoeconomic system, is presented. The conclusion is made about the generally successful structural modernization of American industry in the inter-crisis period, characterized as the initial stage of the reindustrial development of the United States on the basis of convergent technologies of the sixth technological order. The problems of the initial stage of American reindustrialization associated with a small increase in industrial production within the framework of the national knowledge economy and the strengthening of structural imbalances in its spatial development are identified. At the same time, a high level of efficiency of modernization of the main industries of the United States in the considered period of time was noted, associated with the active diffusion of convergent technologies.
DEVELOPING A PRELIMINARY CHECKLIST FOR VOCABULARY TASK EVALUATION
Authors: Laaribi Manal
Published: April 2022

Language teachers are usually provided with textbook material that contains several tasks and activities. Although these activities are meant to facilitate the learning and teaching processes, it is important to approach the provided material critically, make the necessary adjustments to its components, and contextualize its themes. The use of a checklist may render this process of adopting and adapting material feasible and effective since a checklist provides a practical systematic approach to analysis. This paper will provide the reader with a preliminary design of a checklist for vocabulary task evaluation that includes a 5-point Likert scale and contains eight main items and twenty-two sub-items that represent some of the main principles of vocabulary learning. These principles have been incorporated into the checklist on the basis of relevant literature and perspectives of different researchers, experienced teachers, and teacher trainers. This paper will also provide the reader with a demonstration of the use of this checklist through the analysis of a unit’s vocabulary section of the book “Gateway to English 2.”
A MULTILINGUAL TURN: TRANSLANGUAGING BY DESIGN ACTIVITY IN AN EFL CONTEXT
Authors: Zano Kufakunesu
Published: April 2022

Translanguaging can be the latest all-embracing approach in language policy and assessment needed to substitute previous linguistic practices that treated languages as separate entities in a globalised world. This study is based on translanguaging by analysing activities that involved two cartoons in a multilingual classroom. This research was conducted to determine the opinions of Grade 12 EFAL learners on translanguaging by design activity in a multilingual setting. Grade 12 EFAL were chosen for their rich exposure to analysing cartoons. The class had 35 learners who were put in 5 focus groups to analyse the two cartoons. The 2017 cartoon had 5 questions and the 2018 cartoon had 4 questions, which learners answered in groups. The results indicate that translanguaging is an empowering tool that gives the learners a sense of ownership and belonging as they manipulate their previous linguistic knowledge to explore the given task. The teacher needs to alert the learners that they are free to use their home languages together with English to do an activity. This will help learners realise that there is not much difference between English and their home languages as they answer the questions. Teachers need to be multilingual so that they remain culturally and linguistically relevant to the learners.

THE USE OF INDONESIAN FOLKLORES TO DEVELOP YOUNG LEARNERS’ ANALYTICAL AND CRITICAL REASONING SKILLS
Authors: Yoedo Yuli Christiana , Mustofa Ali
Published: April 2022

This study explored the way in which Elementary School teachers used Indonesian folklore in their English classes to help students improve their analytical and critical reasoning skills. Visual culture theory was employed to examine data from interviews through the use of pictures. Moreover, Kress’ (1991) social-constructionist method was applied to investigate the additional realities of folktales as a cultural reality. A descriptive qualitative research method was implemented. The data used were the five English teachers’ teaching strategies. The study revealed that the teachers’ final goal was for students to understand the moral message in the folklore. The teachers were innovative in their teaching materials and approach in their EFL classes by integrating illustrations and other visual media related to folklore in language teaching. Visual media was believed to help language development and vice versa. The strategies included the use of videos with English subtitles, reading texts, questions and examples from real life. The teachers’ efforts were aimed at sharpening students’ analytical reasoning skills. Students needed to answer questions that strengthened their critical reasoning skills, identifying inequities and providing feasible solutions. Teachers, who had a crucial role in maximizing the advantage of using folklore, needed to tailor the story’s discussion to the students’ level of understanding. The outcome of the study inferred that the use of English translations of Indonesian folktales in the classroom potentially affected students’ English language development.
Re-evaluation of continuously reinforced concrete pavement structural model
Authors: Salles de Salles Lucio , Khazanovich Lev , Tadeu Balbo Jose
Published: April 2022

Transversal shrinkage cracks are allowed to develop freely at the slab’s surface of continuously reinforced concrete pavements (CRCP). It is commonly believed that cracking pattern significantly affects CRCP performance: small crack spacing (cluster cracking) is considered to be problematic due to the higher potential for cracks intersection and punchout development whereas large crack spacing can be detrimental for load transfer efficiency (LTE) at the crack due to the development of wider cracks. The Mechanistic-Empirical Pavement Design Guide (MEPDG) procedure for prediction of critical structural responses in CRCP is based on ISLAB2000 finite element model with constant crack spacing and equal LTE for every crack. The critical stresses are assumed to be at the top of the CRCP surface mid-distance between the cracks. However, results of experimental studies suggested that this model may not adequately describe CRCP’s structural behavior. This paper presents a re-evaluation of the procedure for critical stress predictions. A finite element model with a variable crack spacing was developed. Different load positions, thermal differentials, crack LTE levels, axle types and voids were also simulated. Results point out that the location of critical stresses depends on many parameters, including crack spacing, magnitude of temperature gradients, type of axle load and presence or not of voids. Therefore, other modes of punchout initiation, currently not taken into account in the MEPDG, should be considered in the design process.
Ready-Mixed Foamed Cellular Concrete as Engineered Backfill Material
Authors: Montemayor Roberto , Roesler Jeffery , Lange David
Published: April 2022

Backfill materials can be excavated soils, granular materials, or cementitious flowable materials. Depending on the application, backfill materials require specific properties such as workability for placement, resistant to settlement, minimum strength, and durability. Backfill materials must distribute loads to reduce vertical and lateral pressures on adjacent or underlying infrastructure components as well as existing materials. Historically, backfill materials are susceptible to poor quality control, high material heterogeneity and segregation, erosion, and sometimes excessive strength. Foamed cellular concrete (FCC) offers an alternative engineered material that can achieve a specified density and compressive strength while still providing superior placement efficiency and durability relative to traditional backfill materials. The density of FCC ranges from 300 to 1800 kg/m$^3$ and is achieved by the incorporating a high volume but stable air system inside the cementitious paste. Likewise, the compressive strength of FCC can be tailored from 10 to 130 kg/cm$^2$. FCC can be batched using traditional ready-mix equipment and only requires cement, water, and a foaming agent. Admixtures are beneficial to improve workability and paste stability properties while maintaining a reasonable cost. Other benefits of FCC for backfill applications are self-compacting and self-leveling, lightweight for reducing overburden, pumpability, erosion resistant, and thermal insulating, which makes it attractive for utility and drainage trenches, void filling, support layer for pavement patching, and for filling abandoned conduits.
NEW CONCEPTS FOR DESIGNING BRIDGE APPROACH SLABS
Authors: Sun Peizhi , Zollinger Dan
Published: April 2022

The well-known bump-at-the-end-of-the-bridge often involves the joint between the bridge approach slab (BAS) and a bridge deck as the root cause has been a recurring nationwide issue over the years. DOTs have reported that the roughness and the associated slab cracking near this joint have significantly reduced ride quality. Recent field investigations have found that similar problems can also develop at the BAS – pavement joint due to erosion that has taken place underneath it. Considerations are provided in this paper with respect to how potential erosion could be better addressed by addressing the factors that affect it in the design of the BAS thickness. An approach previously developed by the research team is briefly introduced to facilitate the prediction of erosion damage occurring underneath the BAS – pavement joint. As a means to improve the current methodology for designing the thickness of BASs, this paper elaborates a modified mechanistic – empirical design procedure using a an “erosion-based slab thickness” concept to account for the effect of the erosion damage on the structural capacity of the BAS; reliability considerations with respect to the cracking performance of BASs are also provided to facilitate the design process.
Application of a poromechanistic-empirical drying shrinkage modeling approach to structural design of concrete pavements
Authors: Rangelov Milena , Nassiri Somayeh
Published: April 2022

Top-down drying in concrete pavement slabs causes differential drying shrinkage strains ($\varepsilon_{sh}$), which may warp the slab and lead to cracking. Warping is typically represented by an equivalent temperature difference ($ETD_{sh}$) that will cause the same slab curvature as $\varepsilon_{sh}$. However, the current $ETD_{sh}$ computation procedures are empirical and simplified. In this study, a poromechanistic-empirical (PME) procedure is proposed to compute time-dependent $ETD_{sh}$ for concrete pavements. The PME procedure integrates a diffusion model to predict the internal relative humidity with a poromechanistic model to calculate $\varepsilon_{sh}$-profiles. Both models are calibrated based on differential drying experiments conducted on mortar prims from seven mixture designs. After applying an empirical correction for coarse aggregate volume, the developed $\varepsilon_{sh}$-profiles are used to calculate $ETD_{sh}$ for an instrumented pavement section in Pennsylvania for validation. Higher sensitivity of the PME procedure compared to the current pavement design guide, AASHTOWare PavementME, to both mixture design and climate is demonstrated for four pavement sections. The largest difference in $ETD_{sh}$ among the climates is 33$^\circ$C based on the PME procedure, as opposed to only 2$^\circ$C by PavementME. PME $ETD_{sh}$ also shows the benefits of fly ash and low w/cm to mitigate warping, especially in dry non-freeze climates.
A Framework to Assess Early Concrete Slab Cracking
Authors: Joshaghani Alireza , Zollinger Dan
Published: April 2022

This research was based on the findings from a field study of slab placements representing different combinations of curing conditions and placement times. One of the key objectives was to collect data with respect to slab setting characteristics as a function of the quality of curing provided for each slab. The set is referred to herein terms of a gradient that forms due to environmental effects on temperature and moisture profile variations during the initial days after placement. These profile variations effect the degree of slab support. In other words, early-age concrete temperature and moisture history is a key factor affecting the set gradient, as well as a factor in slab curling and warping behavior (corner displacement). There is also a strain profile associated with the set gradient creating a level of stress that can be related to the development of early-age cracking similar to slab curling and warping. This early-aged behavior is mostly drying shrinkage driven, and is often manifested by the separation of the slab from the substrate along the edges and the corners of the slab. This paper mainly focuses on a framework to relate early-age slab damage to the probability of slab cracking later in the performance cycle. This relationship is elaborated with respect to curing quality and its effect on the development of the set gradient as well as its role in PavementME calibration results. The PavementME developers were aware that construction weather conditions affect concrete pavement performance via the inclusion of a set gradient in the computations.
Causes Of Distress In Cement Concrete Pavement On Black Cotton Soil And Remedy
Authors: Jain R.K. , Bongirwar P.L. , Kulkarni U.V. , Kiran Babu G.V.M. , Kumar Raman
Published: April 2022

Black Cotton (BC) soil is present in large parts of India. This soil absorbs lot of water while getting wet and swells even more than 50% which is called Free Swelling Index (FSI). If swelling is prevented, it exerts lot of pressure on the pavement and causes all types of cracks. The CBR of this soil is between 2% to 3.5%. Indian design guidelines provide for Cement Concrete Pavement (CCP), a minimum of 8% CBR for subgrade. While constructing CCP on BC soils special precautions are needed, otherwise distresses will develop. If the new pavement is to be constructed, the remedy lies in removal of the BC soil up to a depth of about 2m from Natural Ground Level (NGL), and treating the underlying soil in construction prism with lime and cement ensuring 12% CBR and 98% compaction. In this case study a 10m wide CCP was built on existing 7m wide flexible pavement by removing the bituminous layer overlaid with Granular Sub-base and Roller Compacted Concrete. Fresh shoulders 1.5m wide on each side were added. The road failed prematurely. Study involved investigation of reasons for the failure of CCP on a highway. The distress is found to be in the form of wide and long longitudinal cracks with faulting at a few places, as well as transverse cracks, multiple cracks and corner breaks in some panels. In-situ stabilisation of Black Cotton Soil is suggested as an effective remedy to mitigate the problem to a large extent.
A review of the ``trigger'' to reseal contraction joints in plain concrete pavements
Authors: Vorobieff George
Published: April 2022

This paper provides a critical review of the ‘trigger’ to reseal transverse contraction joints in plain concrete pavements given that sealant distress is not uniform along the joint length, traffic management costs are a significant cost, minimising traffic disruption at high volume sites is important, and maintenance funding being limited and directed to ‘safety first’ maintenance activities. In NSW, Australia, all contraction joints are sealed with a highway grade silicone sealant. When sealed with the reservoir clean and dry, the joint sealant should remain in place without cracking for at least 15 years. However, joints sealed incorrectly typically result in early age adhesion failure. Poor joint cleanliness or sealing too early, has been shown to result in seal distress under the wheel paths within the first 2 years. It is also common for the sealant to become distressed in the slow (outer) lane while the sealant is in satisfactory condition in the fast (inner) lane. Recommendations for an interim empirical procedure are provided to assist asset managers evaluate the ‘triggers’ for resealing existing joints. The recommendations are based on the age of the pavement and incorporate: (a) Simplified definition for sealant defect, (b) Implementation of a random inspection technique to determine the extent of seal distress and more informed decision making on contraction joints to be resealed, and (c) The extent of resealing in a transverse joint over multiple lanes.
A Teachable Moment? David Hume and the Tower of Babel
Authors: Hearn Jonathan
Published: April 2022

This essay reflects on the de-naming of the David Hume Tower at Edinburgh University in September 2020. It critically examines and contextualises the racist footnote written by Hume, that was the focus of calls to remove his name from the building. It argues that an opportunity was lost to ask deeper questions about the contribution of David Hume to current thought, and why we may want to commemorate historical figures, despite their flaws. In short, a ‘teachable moment’ was squandered in this event. I conclude by suggesting that such symbolic gestures as the de-naming of the David Hume Tower are not effective ways to oppose racism.

Hot and dry Mediterranean ecoregions are characterized by low soil organic carbon content and large potential to become carbon sink when appropriately managed. Soil carbon sequestration may also play an important role in improving the resilience of these vulnerable agroecosystems to increasingly drastic impacts of global climate change. One agricultural practice that aims to increase soil organic carbon stocks, among other beneficial outcomes, is the use of cover crops. Although cover crops can increase soil organic carbon content, recent studies have observed that cover crops may lead to lower soil carbon stocks when considering co-management strategies, especially at greater soil depths. In this review, we outline the current paradigm of soil organic carbon dynamics and aim to apply our current understanding of soil carbon sequestration processes to cover crop management. We review how cover crop practices such as cover crop species selection, growth duration, and termination methodologies may impact soil organic matter sequestration and stabilization processes and provide insights to direct future research and inform cover crop management for C sequestration in Mediterranean agroecosystems.

Zinc-modified titanium materials have been widely applied in oral implants. Among them, our previous studies have also successfully prepared a novel acid-etched microstructured titanium surface modified with zinc-containing nanowires (Ti-NW-Zn) and proved its excellent biocompatibility. It is well known that the functional regulation between angiogenesis and osteogenesis is of great importance for bone remodeling around implants. However, there are few reports concerning the biological safety of zinc ions released from materials and the appropriate concentration of released zinc ions which was more conducive to angiogenesis and bone regeneration. In this study, we investigated the effects of zinc ions released from Ti-NW-Zn surfaces on angiogenesis and osteogenesis using the zebrafish model and revealed the relationship between angiogenesis and osteogenesis via HUVECs and MC3T3-E1s in vitro. We found that the zinc ions released from Ti-NW-Zn surfaces, with a concentration lower than median lethal concentrations (LCs) of zebrafish, were biologically safe and promote osteogenesis and angiogenesis in vivo. Moreover, the proper concentration of zinc ions could induce the proliferation of HUVECs and osteogenic differentiation. The positive effects of the appropriate concentration of zinc ions on osteoblast behaviors might be regulated by activating the MAPK/ERK signaling pathway. These aspects may provide new sights into the mechanisms underlying zinc-modified titanium surfaces between osteogenesis and angiogenesis, to lay the foundation for further improving the materials, meanwhile, promoting the applications in dentistry.

After amputation, axolotl salamanders can regenerate their limbs, but the degree to which limb regeneration recapitulates limb development remains unclear. One limitation in answering this question is our lack of knowledge about salamander limb development. Here, we address this question by studying expression patterns of genes important for limb patterning during axolotl salamander limb development and regeneration. We focus on the Wnt signaling pathway because it regulates multiple functions during tetrapod limb development, including limb bud initiation, outgrowth, patterning, and skeletal differentiation. We use fluorescence in situ hybridization to show the expression of Wnt ligands, Wnt receptors, and limb patterning genes in developing and regenerating limbs. Inhibition of Wnt ligand secretion permanently blocks limb bud outgrowth when treated early in limb development. Inhibiting Wnt signaling during limb outgrowth decreases the expression of critical signaling genes, including Fgf10, Fgf8, and Shh, leading to the reduced outgrowth of the limb. Patterns of gene expression are similar between developing and regenerating limbs. Inhibition of Wnt signaling during regeneration impacted patterning gene expression similarly. Overall, our findings suggest that limb development and regeneration utilize Wnt signaling similarly. It also provides new insights into the interaction of Wnt signaling with other signaling pathways during salamander limb development and regeneration.
Evolving Insights Into the Biological Function and Clinical Significance of Long Noncoding RNA in Glioblastoma

Published: April 2022

Glioblastoma (GBM) is one of the most prevalent and aggressive cancers worldwide. The overall survival period of GBM patients is only 15 months even with standard combination therapy. The absence of validated biomarkers for early diagnosis mainly accounts for worse clinical outcomes of GBM patients. Thus, there is an urgent requirement to characterize more biomarkers for the early diagnosis of GBM patients. In addition, the detailed molecular basis during GBM pathogenesis and oncogenesis is not fully understood, highlighting that it is of great significance to elucidate the molecular mechanisms of GBM initiation and development. Recently, accumulated pieces of evidence have revealed the central roles of long noncoding RNAs (lncRNAs) in the tumorigenesis and progression of GBM by binding with DNA, RNA, or protein. Targeting those oncogenic lncRNAs in GBM may be promising to develop more effective therapeutics. Furthermore, a better understanding of the biological function and underlying molecular basis of dysregulated lncRNAs in GBM initiation and development will offer new insights into GBM early diagnosis and develop novel treatments for GBM patients. Herein, this review builds on previous studies to summarize the dysregulated lncRNAs in GBM and their unique biological functions during GBM tumorigenesis and progression. In addition, new insights and challenges of lncRNA-based diagnostic and therapeutic potentials for GBM patients were also introduced.
