The trauma of the Great War in the Serbian avangard novel
Authors: Petrović Predrag
Published: March 2022

The Serbian avant-garde novel expresses war experience that goes from nihilistic experience of historical terror and complete collapse of all values to the activation of vitalistic potentials, exaltation of the senses, physicality, sexuality, the need for reconstruction and new establishment of the individual and the collective being. This is evident in each of the mentioned novels: in The Journal of Čarnojević (Dnevnik o Čarnojeviću) it moves from the senselessness of the war to the need for metaphysical consolation; in Red Fogs (Crvene magle) heroes are facing both cowardice and desertion, but also find the strength to sacrifice themselves for others and make heroic gestures that a man is capable of making only in war; in The Wings (Krila) there is a range of phenomena from grotesque and horror to visions that war pilots experience while observing the skies. Finally, the novel The Sixth Day (Dan šesti) tells a brilliant story of war and peace, of the everlasting cycle of birth and death on the earth. The literature that was created in the years immediately following the Great War is characterized by the motifs of disappointment, disaster and revulsion for the forces of destruction. It doubts the ethical and humanistic values. The literature calls into question the social progress and the ability of history to give answers to the questions about the meaning of life and of the world.

Authors: Silva Alexsandro da , Dutra Ademar
Published: March 2022

O setor público hoje enfrenta uma variedade de eventos complexos e desafiadores, e medidas adequadas são necessárias para garantir que o valor público percebido seja mantido em certos níveis. No entanto, existe uma lacuna na literatura a respeito da gestão de risco no setor público. Não existe um fundo teórico bem estabelecido de gestão estratégica de riscos no setor público e a maioria dos disponíveis a literatura concentra-se apenas na estimativa de risco e falha em contribuir mais para como essas estimativas podem ser introduzidos no processo de tomada de decisão nas autoridades públicas. Este trabalho estudo de natureza exploratória com abordagem qualitativa teve como objetivo compreender como a literatura internacional tem abordado a gestão de risco no setor público. Para tanto, o ProKnow-C foi utilizado como instrumento para seleção do portfólio bibliográfico e análise sistêmica segundo a filiação teórica construtivista de avaliação de desempenho. Dos dados secundários identificou a existência, no período de 2010 a 2020, de 25 publicações que representam o fragmento da literatura de interesse, e os resultados obtidos permitiram a identificação de lacunas de pesquisa e promovem direcionamentos futuros de pesquisa ao não identificar métodos que considerem as particularidades do contexto da gestão de risco no setor público.
Federal cybersecurity awareness programs :
Authors: Haney Julie , Jacobs Jody , Furman Susanne , Barrientos Fernando
Published: March 2022

Prior industry surveys and research studies have revealed that organizational security awareness programs may face a number of challenges, including lack of: leadership support; resources; and staff with sufficient background and skills to implement an effective and engaging program. However, no prior research has explored security awareness programs specifically in the United States (U.S.) government (federal) sector. To address this gap, NIST conducted a two-phase, mixed methods research study to understand the needs, challenges, and practices of federal security awareness programs. This report describes the research background and methodology, along with the characteristics of the participants, organizations, and programs represented in the study. Research results can serve as a resource for federal security awareness professionals, managers, and organizational decision makers to improve and advocate for their organizations' security awareness programs. Results can also inform the development of federal security awareness guidance, policies, sharing forums, and initiatives meant to aid programs in becoming more effective. While focused on the U.S. government, findings may also have implications for organizational security awareness programs in other sectors.

Organizational security awareness programs may experience a number of challenges, including lack of resources, difficulty measuring the impact of the program, and perceptions among the workforce that training is a boring, check-the-box activity. While prior surveys and research have examined programs in the private sector, there is little understanding of whether these findings also apply within the U.S. government. To address this gap and better understand the needs, challenges, practices, and necessary competencies of federal security awareness teams and programs, NIST conducted a comprehensive, two-phase research study that leveraged both qualitative and quantitative methodologies. This companion document to NISTIR XXXX Federal Cybersecurity Awareness Programs: A Mixed Methods Research Study reports on a subset of study results focused on identifying the current approaches and challenges of security awareness programs within the federal government. Insights gained from these results are informing guidance and other initiatives to aid federal organizations in building effective security awareness programs. While focused on the U.S. government, findings may also have implications for organizational security awareness programs in other sectors.

Published: March 2022

ABSTRACT:
In this study, the automation of an assembly process using a collaborative robotic arm (Cobot) was analyzed. The manual process is the assembly of a Lego® bricks structure and was analyzed using the technique of predetermined movements MTM-1. Moves were defined and processing time was set. The results obtained show that the automated process can increase production capacity by up to 40% using the same personnel as the manual process, but in different shifts. Likewise, defects due to a bad union between the edges of the bricks, which is the main problem in the manual process, are avoided. Finally, the automation process was detailed by associating the manual movements with the Cobot® commands in the simulation environment of the PolyScope Robot User Interface®. What has application to automate other types of manufacturing sequences and manual assemblies.
Keywords: Automatization, Robotic arm; Methods-Time Measurement; Cobot®; Lego® bricks.

Cutting the vicious circle: Addressing the inconsistency in teachers’ approaches to academic integrity breaches
Authors: Dannhoferová Jana , Foltýnek Tomáš , Dlabolová Dita , Fishman Teddi
Published: March 2022

Dysfunctional educational system has been identified as one of the causes of academic dishonesty in Eastern Europe. This case study combines quantitative self-reported data and qualitative data from students and teachers with hard data from the disciplinary committee, collected at one Czech university. We analyse cases and types of breaches, identify characteristics of students that incline them toward cheating and investigate some of the reasons why. Our research confirms that the inconsistent approach of teachers is a contributing factor to students’ propensity to violate academic integrity rules and identifies reasons for such behaviour. Teachers play a key role in prevention, it is their duty to report cases of suspected misconduct, but they need tools to improve the culture of academic integrity. The contribution of this paper is to provide an inspiration for policy makers how to tackle the inconsistency of teachers’ approaches to student misconduct.

Authors: Sharma Ambuj , Malik Reena , Nagy Henrietta
Published: March 2022

In India, changes in legislation and policy have increased the number of students with disabilities enrolled in higher education. The purpose of this study was to investigate university teachers’ perceptions towards inclusion of students with disability public and private universities in India. The study examined how age, gender, educational levels, years of teaching experience, and frequency of interaction with a person with a disability influence instructors’ views about people with disabilities and their inclusion at public and private academic institutions. Data was collected through a digital questionnaire from private and public universities in Pune, India. The population of the study comprised of full time University teachers’ (under-graduate, post-graduate and doctoral courses) in Pune. The survey was completed by 309 university teachers. Descriptive statistics, independent sample t-test and ANOVA were used to examine the data. The researchers found no statistically significant relationships between teachers’ perceptions of inclusion in regards to degree level, gender and years of experience. The study did, however, discover a statistically significant relationship between teachers’ perceptions of inclusion and their interaction with students with disabilities. Academic and social outcomes of students with disabilities are significantly enhanced when inclusive approaches are used. Goals for future research are discussed.

Published: March 2022

The COVID-19 pandemic outbreak has upended the educational system worldwide, possibly with severe long-term consequences as most training institutions were forced to move to an online environment. Given the sudden transition to remote education, the main objective of this contribution is to evaluate the impact of distance education on examination results. We investigated the examination results of tax related subjects collected at the Czech University of Life Sciences in Prague during the period from 2014 to 2020. The sample consists of examination results of 120 different classes within 6 years with a total amount of 7268 observations. Firstly, we pivoted the data into the long format and performed binary logistic regression. Our findings suggest that the odds that student successfully passes the exam increases if the student was examined online compared to in-person. Additionally, we used KNN regression which enables us to predict success rate for an upcoming semester. According to our analysis, it is expected that on average 82 students out of 100 will successfully pass the exam. The model was calibrated using cross-validation to choose optimal K.

Authors: Berková Kateřina , Holečková Lenka
Published: March 2022

The aim of the study is to verify employers and university students’ perception of the importance of professional and soft competencies that is placed on the position of financial accountant in the Czech Republic. The study is based on the international knowledge oriented to the difference between university students and employers in perception of the importance of professional and soft competencies. The research is focused on Czech companies from two regions and students of Accounting and Finance attending universities from two different regions. The research was conducted with the help of advertisement analysis and a questionnaire survey in the first quarter of 2020. In the advertisements, mainly the information literacy and usage of English language in accounting appeared. The perception of employers is not in accordance with the importance of competencies perceived by students who would like to work in the accounting profession. Responsibility, reliability, accuracy, and independence are important for students. Differences in the perception of competencies importance were not found. This study contributes to the identification of the competency’s importance regarding employers and students. It will be necessary to innovate teaching methods with the emphasis on the effective readiness of graduates for the accounting profession.

Школске библиотеке представљају најбројнији тип библиотека на територији Србије. У школама, које образују децу са инвалидитетом, сходно врсти и обиму инвалидитета, индивидуалним потребама и могућностима ученика, организује се велики број разноврсних ваннаставних активности које допринесе образовању и социјализацији ове популације. Библиотекар у овим школама је све мање библиотекар у традиционалном смислу речи, а све више члан школских тимова, који пружа подршку целокупном васпитно-образовним процесу. Бројне активности представљају плод заједничког рада наставника, ученика и библиотекара који свој план културних активности усклађује са плановима одговарајућих актива (учитеља, наставника српског језика, наставника музичке и ликовне културе), а уз велику примену савремене информационе технологије и средстава асистивне технологије. Посебно треба истаћи да, школе које образују децу и младе са инвалидитетом, да би што успешније задовољиле потребе и интересовања ученика, активно сарађују са редовним основним школама, јавним библиотекама и другим установама у локалној заједници.

Lead-free K1–xNaxNbO3 thin films, as a candidate for sensors and electromechanical and electrocaloric cooling devices, have increasingly received attention. However, for (111)-oriented films, the relation between phase transitions and electrocaloric effect is not clear. Here, we derive the thermodynamic potential of (111)-oriented thin film ferroelectrics K1–xNaxNbO3 based on the 8th order polynomial function, and then establish the temperature-misfit strain and out-of-plane stress-in-plane misfit strain phase diagrams and calculate electrocaloric (EC) entropy changes ΔS and temperature changes ΔT. This study focuses on mechanical and orientation controls of room-temperature EC effect of K0.5Na0.5NbO3 films, which is critical for environmentally friendly electrocaloric refrigeration applications in practice. Under the stress-free and zero misfit strain conditions, the (111)-oriented K0.5Na0.5NbO3 film in an electric field of 30 MV/m has a maximum EC ΔT of ～18 K near the rhombohedral ferroelectric-paraelectric phase transition temperature (about 673 K). However, an out-of-plane stress of about –6.7GPa can reduce the optimal operating temperature to room temperature where the K0.5Na0.5NbO3 film has the EC ΔT of ～7.5 K under the action of applied electric field of 30 MV/m. The present work provides theoretical guidance for exploring the strain engineering and orientation engineering of K1–xNaxNbO3-based thin films with optimized electrocaloric and electromechanical properties.
Knee Pain Reduction Using a Shock-Absorbing Sole
Authors: Ross Arnold S. , Jones Lester J.
Published: March 2022

Background: The biomechanics of the foot and leg are responsible for shock absorption during human gait. Lack of shock absorption is known to be a key component of knee pain. This study compares a new model of shoe sole with a built-in modification intended to absorb shock with a traditional sole shoe to examine whether shoe design modifications can help alleviate knee pain.

Methods: A double-blind randomized controlled study was performed. Fifty-two adults with overuse symptoms of knee pain, either unilateral or bilateral, were enrolled and randomly assigned to use the intervention sole or the traditional sole shoes. For 5 weeks, participants wore either the shoe with the intervention sole or the shoe with the traditional sole, rating their knee pain on a 10-point visual analog scale at study onset, midway, and study completion.

Results: After 5 weeks, participants using the intervention sole shoe reported an average reduction in knee pain of 85%, significantly better than participants using the traditional sole shoe (P < .001), whose average pain scores increased. Positive effects on back and foot pain were also observed in those with the intervention sole shoe compared with the traditional sole shoe.

Conclusions: The intervention shock-absorbing sole represents an approach to midsole and outsole construction that can potentially increase shock absorption and decrease knee pain during prolonged standing and walking.
A Focus on Amputation Level: Factors Preventing Length Preservation in the National Inpatient Sample

Published: March 2022

Background: Diabetic lower-extremity disease is the primary driver of mortality in patients with diabetes. Amputations at the forefoot or ankle preserve limb length, increase function, and, ultimately, reduce deconditioning and mortality compared with higher-level amputations, such as below-the-knee amputations (BKAs). We sought to identify risk factors associated with amputation level to understand barriers to length-preserving amputations (LPAs).

Methods: Diabetic lower-extremity admissions were extracted from the 2012-2014 National Inpatient Survey using ICD-9-CM diagnosis codes. The main outcome was a two-level variable consisting of LPAs (transmetatarsal, Syme, and Chopart) versus BKAs. Logistic regression analysis was used to determine contributions of patient- and hospital-level factors to likelihood of undergoing LPA versus BKA.

Results: The study cohort represented 110,355 admissions nationally: 42,375 LPAs and 67,980 BKAs. The population was predominantly white (56.85%), older than 50 years (82.55%), and male (70.38%). On multivariate analysis, living in an urban area (relative risk ratio [RRR] = 1.48; P < .0001) and having vascular intervention in the same hospital stay (RRR = 2.96; P < .0001) were predictive of LPA. Patients from rural locations but treated in urban centers were more likely to receive BKA. Minorities were more likely to present with severe disease, limiting delivery of LPAs. A high Elixhauser comorbidity score was related to BKA receipt.

Conclusions: This study identifies delivery biases in amputation level for patients without access to large, urban hospitals. Rural patients seeking care in these centers are more likely to receive higher-level amputations. Further examination is required to determine whether earlier referral to multidisciplinary centers is more effective at reducing BKA rates versus satellite centers in rural localities.
Comparison of Self-adhesive Taping and Short-Leg Casting to Treat Tuberosity Fractures of the Proximal Fifth Metatarsal: A Prospective Study
Authors: Batıbay Sefa , Bayram Serkan , Duman Sedat , Karaytuğ Kayahan , Camur Savas
Published: March 2022

Background: The aim of this study is to compare clinical and radiologic outcomes of self-adhesive taping (SAT) or a short- leg cast (SLC) groups with base of fifth metatarsi.

Methods: Functional outcome was assessed by the Visual-Analogue-Scale Foot and Ankle (VAS-FA) at the Emergency and at 2, 4, 6, and 12 weeks. Labour loss, bone union and The American Orthopedic Foot and Ankle Score (AOFAS) at 12 weeks were also assessed.

Results: There was no difference between the SAT group and SLC group in VAS-FA scores at time of injury, 6 and 12 weeks. The SAT group had a significantly higher mean VAS-FA score at the second and fourth weeks of follow-up compared with the SLC group (P = .001 and P = .039, respectively). No correlation was observed between the fracture gap and functional scores for both groups. There was no difference in AOFAS between two groups at 12 weeks. Twenty one patients were unable to work for a mean of 38.2 days during the treatment. 10 patients with the SAT missed 37.5 days and eleven patients with the SLC g missed 40.2 (p: 0.41). The bone union was also achieved for all patients within 12 weeks.

Conclusion: Treatment with SAT in these fractures had satisfactory functional results compared with traditional SLC. Although there were no significant differences in labor loss and use of assistive devices, The VAS-FA score was significantly higher in SAT group than the SLC group at the second and fourth weeks of treatment.
Evaluation of the Correlation Between Flamenco Dance and Ankle and Foot Posture
Authors: Castro-Méndez Aurora , Mateos-Martínez Desidero , Castillo-López José M. , Vargas-Macías Alfonso
Published: March 2022

Background: The practice of flamenco dance involves great biomechanical demands, comparable with a high-performance sport. The technical movements of the footwork tap, the jumps, and the turns increase the prevalence of injuries and pathologic disorders of the foot and lower limb. Limited research has examined adaptation of the foot posture and dorsiflexion of the ankle in flamenco dancing. Therefore, the aim of this study was to evaluate whether the practice of flamenco dancing produces modifications in the ankle’s dorsiflexion range of motion, Foot Posture Index, or pronation.

Methods: A cross-sectional observational study with intentional sampling was performed with 26 individuals (52 feet) in two groups: professional female flamenco dancers (n = 13) and nondancers (n = 13). The participants were assessed in a single session for ankle dorsiflexion, foot pronation (navicular drop test), and foot posture (Foot Posture Index).

Results: Significant differences were found between the two groups for left foot Foot Posture Index (P = .007) and right foot navicular drop test (P = .006).

Conclusions: The results of this study indicate that flamenco dancing can produce modifications in the Foot Posture Index and foot pronation versus nondancers. Further research is required.
The Cotton Osteotomy as an Adjunct Procedure in Hallux Valgus and Hallux Limitus Surgery
Authors: Chambers LT Aaron R. , Gibboney LT Michael D. , Song Kayla Y.
Published: March 2022

The Cotton osteotomy, as described in 1936 by Frederic Cotton, consisted of a medial cuneiform opening base wedge osteotomy. This Cotton osteotomy served to restore the “triangle of support” of the foot. In his address to the New England Surgical Society, he described this osteotomy as being multipurpose; it can be used for plantarflexion in hallux valgus surgery and has use in hallux rigidus conditions. Since its inception, the procedure has become a popular adjunct to aid in the restoration of the medial column deformity present in pes planus. Recently, there has been renewed interest in the use of the procedure to aid in the correction of deformities involving metatarsus primus elevatus, specifically, hallux valgus and hallux limitus. The advantage of the use of this procedure as opposed to others is that it allows for the preservation and/or restoration of first ray length and the preservation of motion at the medial column. In retrospective review, the authors evaluated seven cases with a 1-year follow-up. In this series of cases, the Cotton osteotomy was performed as an adjunct to common hallux valgus procedures or hallux limitus corrections. Radiographic review was also performed evaluating for initial evidence of radiographic bone-graft healing and patient weightbearing. Although not without its own limitations, the Cotton osteotomy offers several advantages with minimal complications, proving to be a valuable underused resource in the foot and ankle surgeon’s toolkit.

Centrioles are formed by microtubule triplets in a ninefold symmetric arrangement. In flagellated protists and animal multiciliated cells, accessory structures tethered to specific triplets render the centrioles rotationally asymmetric, a property that is key to cytoskeletal and cellular organization in these contexts. In contrast, centrioles within the centrosome of animal cells display no conspicuous rotational asymmetry. Here, we uncover rotationally asymmetric molecular features in human centrioles. Using ultrastructure expansion microscopy, we show that LRRCC1, the ortholog of a protein originally characterized in flagellate green algae, associates preferentially to two consecutive triplets in the distal lumen of human centrioles. LRRCC1 partially co-localizes and affects the recruitment of another distal component, C2CD3, which also has an asymmetric localization pattern in the centriole lumen. Together, LRRCC1 and C2CD3 delineate a structure reminiscent of a filamentous density observed by electron microscopy in flagellates, termed the ‘acorn.’ Functionally, the depletion of LRRCC1 in human cells induced defects in centriole structure, ciliary assembly, and ciliary signaling, supporting that LRRCC1 cooperates with C2CD3 to organizing the distal region of centrioles. Since a mutation in the LRRCC1 gene has been identified in Joubert syndrome patients, this finding is relevant in the context of human ciliopathies. Taken together, our results demonstrate that rotational asymmetry is an ancient property of centrioles that is broadly conserved in human cells. Our work also reveals that asymmetrically localized proteins are key for primary ciliogenesis and ciliary signaling in human cells.

PML nuclear bodies (PML-NBs) are dynamic interchromosomal macromolecular complexes implicated in epigenetic regulation as well as antiviral defense. During herpesvirus infection, PML-NBs induce epigenetic silencing of viral genomes, however, this defense is antagonized by viral regulatory proteins such as IE1 of human cytomegalovirus (HCMV). Here, we show that PML-NBs undergo a drastic rearrangement into highly enlarged PML cages upon infection with IE1-deficient HCMV. Importantly, our results demonstrate that dual signaling by interferon and DNA damage response is required to elicit giant PML-NBs. DNA labeling revealed that invading HCMV genomes are entrapped inside PML-NBs and remain stably associated with PML cages in a transcriptionally repressed state. Intriguingly, by correlative light and transmission electron microscopy (EM), we observed that PML cages also entrap newly assembled viral capsids demonstrating a second defense layer in cells with incomplete first-line response. Further characterization by 3D EM showed that hundreds of viral capsids are tightly packed into several layers of fibrous PML. Overall, our data indicate that giant PML-NBs arise via combined interferon and DNA damage signaling which triggers entrapment of both nucleic acids and proteinaceous components. This represents a multilayered defense strategy to act in a cytoprotective manner and to combat viral infections.
A flexible and accurate method for electroencephalography rhythms extraction based on circulant singular spectrum analysis
Authors: Hu Hai , Pu Zihang , Wang Peng
Published: March 2022

Rhythms extraction from electroencephalography (EEG) signals can be used to monitor the physiological and pathological states of the brain and has attracted much attention in recent studies. A flexible and accurate method for EEG rhythms extraction was proposed by incorporating a novel circulant singular spectrum analysis (CiSSA). The EEG signals are decomposed into the sum of a set of orthogonal reconstructed components (RCs) at known frequencies. The frequency bandwidth of each RC is limited to a particular brain rhythm band, with no frequency mixing between different RCs. The RCs are then grouped flexibly to extract the desired EEG rhythms based on the known frequencies. The extracted brain rhythms are accurate and no mixed components of other rhythms or artifacts are included. Simulated EEG data based on the Markov Process Amplitude EEG model and experimental EEG data in the eyes-open and eyes-closed states were used to verify the CiSSA-based method. The results showed that the CiSSA-based method is flexible in alpha rhythms extraction and has a higher accuracy in distinguishing between the eyes-open and eyes-closed states, compared with the basic SSA method, the wavelet decomposition method, and the finite impulse response filtering method.

Oral disease represents a major concern among all populations. Despite great efforts that have been made in the past few decades to overcome these diseases; a large part of the world population still suffers from oral diseases which are considered a major reason for the loss of a tooth. Different bacterial species colonizes the oral cavity, some of the bacteria are found to be associated with the cause of one of the most common disease called periodontitis. The infectious nature of periodontopathogens has been studied extensively. Currently, treatment of various oral diseases includes supragingival as well as subgingival debridement, root canal treatment and in severe cases, extraction along with antibiotic therapy to help achieve a pathogen-free environment.Continued research and development in the field of dentistry have brought new approaches in treatment modalities. The use of ozone is one of the latest therapies that has gained the interest of researchers in thepast few decades. Ozone is a pale blue colour gas and is the natural constituent of the atmospheric layer of Earth. It is a modern pharmacological approach that is biocompatible and has shown its effectiveness against bacteria (gram-positive and gram-negative bacteria), viruses, and fungi. The beneficial biological effect of ozone has made its usage at all stages of disease propitious. The explication of the mechanism of ozone at the molecular level has proved to be beneficial in different medical and dental treatments. The use of ozone in clinical practice can be advantageous to the patient in terms of pain relief and treatment time. Therefore,this article briefly reviews the chemical nature of ozone, its therapeutic uses, and the benefits it can provide in the treatment of various oral diseases.

Background and Objectives: The harmful effects of frequent exposure to loud sounds through portable music players (PMPs) in combination with earphones have been suggested to result in a high prevalence of recreational noise-induced hearing loss among children, adolescents, and young adults. The present study aimed to evaluate the effects of an active noise control technology applied to earphones on the preferred listening levels (PLLs) while listening to music in the presence of background noise. Subjects and Methods: Twenty-three adults between 20 and 40 years with normal hearing were recruited for this study. PLLs for listening to pop-rock and classical music were measured in the participants’ ear canal with a commercially available PMP for four earphone/headphone configurations in quiet and noisy conditions. Ear canal insertion loss was measured in open ear conditions as well as earphone/headphone conditions. Results: The average PLL while using earphones and headphones exceeded 85 dBA corresponding to the sound level to induce hearing damage, but in the case of canal earphones with noise cancelling (NC), it was below 75 dBA, corresponding to potentially harmful levels. The background subway noise significantly increased the PLL measured in quiet conditions using any four earphone/headphone types except canal earphones with NC. Canal earphones with NC showed the lowest PLLs compared with participants’ average PLLs using the other three earphone/headphone types. Conclusions: To minimize recreational noise exposure at the risk of PMP use, the use of earphones with NC is recommended in noisy environments.

A series of archaeological evaluations and excavations at Laigh Newton in East Ayrshire (NGR: NS 5937 3684) revealed evidence for intermittent occupation of this valley terrace between the Mesolithic and the Late Iron Age. The plough-truncated archaeology included the remains of a rectangular building and associated features of the mid-late 4th millennium BC, a more ephemeral structure and related pits of the mid-3rd millennium BC, a charcoal-burning pit of the mid-1st millennium AD and two other rectilinear structures of indeterminate date.

An archaeological excavation at Hallhill, Dunbar (NGR NT 674 775), has revealed the remains of a rural medieval settlement. Few such sites have been identified in Scotland. Two irregular structures, an enclosure and other possible structures, as well as numerous pits and several gullies and ditches were identified. Large quantities of medieval pottery were recovered from the fills of many of the features, as well as animal bone, coarse stone and metal artefacts. Further to the north, a sub-square ditched enclosure was also found, although this could not be stratigraphically related to the medieval remains and is undated. Adjacent to it was a pit containing incomplete remains of a human skeleton which have been dated to the Late Bronze Age.

An unenclosed Early Bronze Age cremation cemetery was excavated by CFA Archaeology Ltd (CFA) during a watching brief associated with the construction of a natural gas pipeline from St Fergus to Aberdeen, Aberdeenshire (NGR: NJ 9088 3990), in the summer of 2001. The cremation cemetery contained 41 pits, 29 of which contained cremated human bone, and 11 of these were associated with Collared or Cordoned Urns. The cremations have been radiocarbon dated, through a combination of charcoal and bone apatite, to 2040 to 1500 BC, and the cemetery is the most comprehensively dated in Britain of this period. A variety of grave goods were recovered, including a pair of Golden Eagle talons and a flint foliate knife. A large Mesolithic pit was found in the same location as the cremation pits and was dated to 4510–3970 BC.

This report details the archaeological remains recorded by CFA Archaeology Ltd during a programme of fieldwork at Kiltaraglen, now a residential housing development on a prominent, elevated site at the northern edge of Portree on the Isle of Skye (NGR: NG 476 444). The fieldwork ran from September 2006 until March 2007. The project resulted in the discovery and excavation of varied archaeological remains including timber roundhouses, a circular ditch-defined enclosure, post-alignments and settings, miniature souterrains, probable standing stone sockets and an assortment of pits. An assemblage of Beaker pottery was recovered from two pits but the site was generally artefact-poor and reliance was placed on radiocarbon dating that indicates occupation of the site began in the Early Bronze Age and ended in the medieval period, with most activity occurring during the Later Bronze Age. This is of great interest as archaeological remains dating to the Later Bronze Age on the Isle of Skye have previously been notable only by their absence.

In cloud computing, the resources and memory are dynamically allocated to the user based on their needs. Security is considered as a major issue in cloud as the use of cloud is increased. Intrusion detection is considered as a significant tool to develop a reliable and secure cloud environment. Performing intrusion detection in cloud is a difficult task because of its distributed nature and extensive usage. Intrusion detection system (IDS) is widely considered to find the malicious actions in network. In cloud, most conventional IDS are vulnerable to attacks and have no capability for maintaining the balance between sensitivity and accuracy. Thus, we proposed an effective dragonfly improved invasive weed optimization‐based Shepard convolutional neural network (DIIWO‐based ShCNN) to detect the intruders and to mitigate the attacks in cloud paradigm and are more feasible to detect the intruders with ShCNN. The proposed method outperforms the existing method with maximum accuracy of 0.960%, sensitivity of 0.967%, and specificity 0.961%, respectively.

Perovskite oxides with tailored elements and structures endow promising electrocatalytic properties for hydrogen evolution reaction (HER) due to considerable activity and satisfactory long‐term operating stability. However, the synthesis of 1D perovskite nanostructures with anion dopants remains a challenge, as well as insights into the performance origin from experimental and theoretical views. Herein, combined with electrospinning and phosphatizing strategies, P‐doped Pr0.5La0.5BaCo2O5+δ perovskite nanofibers (P‐PLBC‐F) are reported for highly active HER catalysts. The P‐PLBC‐F catalyst outperforms the classic perovskites and can be comparable to the commercial Pt/C (wtPt = 20%) benchmark, exhibiting a Tafel slope of −32.9 mV dec−1 and overpotential of −307 mV at 500 mA cm−2 disk in alkaline media. The highly catalytic activity benefits from the desired 1D nanostructure, steered electronic structures (charge transfer energy ΔCo‐P = 0.79 eV) and Gibbs free energy for the H* desorption (1.02 eV) induced by the P3− doping, as supported by density functional theory calculations. The findings described here unveil the phosphatizing mechanism of the perovskites for catalyzing the hydrogen production, and broaden horizons in terms of rational designs of novel perovskite‐based catalysts for sustainable energy.
