Performance enhancement of an ultrafast graphene photodetector via
simultaneous two-mode absorption in a hybrid plasmonic waveguide
Authors: Okda Hesham A. , Rabia Sherif I. , Shalaby Hossam M. H.
Published: March 2022

An ultrafast, compact, zero-biased, and complementary metal–oxide
semiconductor-compatible graphene photodetector (PD) based on a
silicon-on-insulator hybrid plasmonic waveguide (HPWG) is proposed.
Lumerical MODE solver is employed to investigate the modal
characteristics of TM-polarized modes in the HPWG composing the PD. It
is shown that the input light can be completely coupled into the
photonic-like and plasmonic-like fundamental TM modes at the PD
section. These two modes are exploited together in the photodetection
process to enhance the PD performance. A rigorous analysis is
performed in order to extract the optoelectronic characteristics of
the single-layer graphene (SLG) used in the proposed structure.
Lumerical 3D-FDTD solver is then employed to quantify the light
interaction of the two aforementioned optical modes with the SLG. With
a proper design at a wavelength of 1550 nm, the PD voltage
responsivity reaches 2.8 V/W, and the photocurrent responsivity is
obtained as 18.5 mA/W, while the corresponding absorption length is
kept below

8

m

and the noise equivalent power is
limited to

. Moreover, as the PD operates under
zero bias, its photoresponse is predominated by the
photothermoelectric mechanism, exhibiting a bandwidth that exceeds
180 GHz while avoiding the dark current.

We have developed new polymer optical interconnect materials that we term refractive index contrast (RIC) polymers that are ideally suited to a wide variety of photonic interconnect applications as the refractive index can be tuned over the range of n = 1.42 to 1.56, while index contrast Δn can be precisely tuned through composition and ultraviolet exposure; the waveguides can be directly patterned in dry films with no wet or dry etching processes required. RIC polymer interconnects thus have the ability to access numerous photonic platforms, including silicon photonic chips, ion-exchange (IOX) glass optical substrates, and optical fiber arrays. We demonstrate for the first time efficient single-mode polymer interconnect fabrication via a maskless lithography approach that exhibits low loss adiabatic coupling (∼1.5dB at 1550nm) to IOX waveguides through the formation of grayscale tapers.
Cybersicherheit von Gehirn-Computer-Schnittstellen

Published: March 2022

Gehirn-Computer-Schnittstellen beflügeln die Hoffnung auf übermenschliche Kräfte: Sie versetzen Nutzer in die Lage, Prothesen und sonstige Geräte allein mit ihren Gedanken zu steuern. Je weiter die Entwicklung der neuen Technologie voranschreitet und in marktfähige Produkte mündet, desto sichtbarer rücken auch potenzielle Sicherheitsrisiken in den Fokus. Denn Angriffe auf Gehirn-Computer-Schnittstellen können neurologische Daten erspähen oder Gehirnaktivitäten manipulieren und dadurch verheerende Schäden verursachen. Der Beitrag geht der Frage auf den Grund, wie die Rechtsordnung den Risiken eines Angriffs auf Gehirn-Computer-Schnittstellen bislang begegnet – und wie sie ihnen künftig begegnen sollte.
LAG-1: A dynamic, integrative model of learning, attention, and gaze
Authors: Barnes Jordan , Blair Mark R. , Walshe R. Calen , Tupper Paul F.
Published: March 2022

It is clear that learning and attention interact, but it is an ongoing challenge to integrate their psychological and neurophysiological descriptions. Here we introduce LAG-1, a dynamic neural field model of learning, attention and gaze, that we fit to human learning and eye-movement data from two category learning experiments. LAG-1 comprises three control systems: one for visuospatial attention, one for saccadic timing and control, and one for category learning. The model is able to extract a kind of information gain from pairwise differences in simple associations between visual features and categories. Providing this gain as a reentrant signal with bottom-up visual information, and in top-down spatial priority, appropriately influences the initiation of saccades. LAG-1 provides a moment-by-moment simulation of the interactions of learning and gaze, and thus simultaneously produces phenomena on many timescales, from the duration of saccades and gaze fixations, to the response times for trials, to the slow optimization of attention toward task relevant information across a whole experiment. With only three free parameters (learning rate, trial impatience, and fixation impatience) LAG-1 produces qualitatively correct fits for learning, behavioural timing and eye movement measures, and also for previously unmodelled empirical phenomena (e.g., fixation orders showing stimulus-specific attention, and decreasing fixation counts during feedback). Because LAG-1 is built to capture attention and gaze generally, we demonstrate how it can be applied to other phenomena of visual cognition such as the free viewing of visual stimuli, visual search, and covert attention.
Impact of 6 month conjugated equine estrogen versus estradiol-treatment on biomarkers and enriched gene sets in healthy mammary tissue of non-human primates
Authors: Hobi Gabriel , Cline J. Mark , Ethun Kelly F. , Simillion Cedric , Keller Irene , Stute Petra
Published: March 2022

Objective

To identify distinctly regulated gene markers and enriched gene sets in breast tissue of cynomolgus monkeys (Macaca fascicularis) treated for six months with either conjugated equine estrogens (CEE) or estradiol (E2) by analysis of corresponding mRNA levels of genes associated with breast development, carcinogenesis, apoptosis and immune regulation. Additionally, translation of three nuclear markers was analyzed.

Methods

RNA from breast biopsies and necropsies was isolated from two independent study trials from Ethun et al. (CEE) and Foth et al. (E2) after 6 month of treatment duration. RNA was subjected to qRT-PCR and MicroArray analysis. Immunohistochemical stainings were performed for the estrogen receptor alpha subunit (ERa), the progesterone receptor (PGR) and the proliferation marker Ki67.

Results

We identified a total of 36 distinctly enriched gene sets. Thirty-one were found in the CEE treatment group and five were found in the E2 treatment group, with no overlap. Furthermore, two individual genes IGFBP1 and SGK493 were upregulated in CEE treated animals. Additional targeted qRT-PCR analysis of ten specific estrogen-related genes showed upregulation of three genes (TFF1, PGR and GREB1) after CEE treatment, respectively one gene (TFF1) after E2 treatment. Immunohistochemical stains of breast biopsies showed a significant increase in expression of the PGR marker after CEE treatment.

Conclusions

In this study we identified enriched gene sets possibly induced by CEE or E2 treatment in various processes associated with cancer biology and immunology. This preliminary translational data supports the concept that different estrogen types have different effects on healthy breast tissue and may help generate hypotheses for future research.
Estimating cetacean population trends from static acoustic monitoring data using Paired Year Ratio Assessment (PYRA)
Authors: Grist Eric P. M. , McKinley Trevelyan J. , Das Saptarshi , Tregenza Tom , Jeffries Aileen , Tregenza Nicholas
Published: March 2022

The cetacean conservationist is often faced with evaluating population trends from abundance data that are either sparse or recorded at different times in different years. The presence of diel or seasonal patterns in the data together with unplanned gaps is often problematic. Such data are typical of those obtained from static acoustic monitoring. We present a simple and transparent non-parametric trend evaluation method, ‘Paired Year Ratio Assessment (PYRA)’ that uses only whole days of data wherever they are present in each of successive pairs of periods of 365 days. We provide a quantitative comparison of the performance of PYRA with traditional generalised additive models (GAMS) and nonparametric randomisation tests that require a greater level of skill and experience for both application and interpretation. We conclude that PYRA is a powerful tool, particularly in the context of identifying population trends which is often the main aim of conservation-targeted acoustic monitoring.

Published: March 2022

In most big cities, public transports are enclosed and crowded spaces. Therefore, they are considered as one of the most important triggers of COVID-19 spread. Most of the existing research related to the mobility of people and COVID-19 spread is focused on investigating highly frequented paths by analyzing data collected from mobile devices, which mainly refer to geo-positioning records. In contrast, this paper tackles the problem by studying mass mobility. The relations between daily mobility on public transport (subway or metro) in three big cities and mortality due to COVID-19 are investigated. Data collected for these purposes come from official sources, such as the web pages of the cities’ local governments. To provide a systematic framework, we applied the IBM Foundational Methodology for Data Science to the epidemiological domain of this paper. Our analysis consists of moving averages with a moving window equal to seven days so as to avoid bias due to weekly tendencies. Among the main findings of this work are: a) New York City and Madrid show similar distribution on studied variables, which resemble a Gauss bell, in contrast to Mexico City, and b) Non-pharmaceutical interventions don’t bring immediate results, and reductions to the number of deaths due to COVID are observed after a certain number of days. This paper yields partial evidence for assessing the effectiveness of public policies in mitigating the COVID-19 pandemic.
Peripheral blood mononuclear cell gene expression and cytokine profiling in patients with intermittent claudication who exhibit exercise induced acute renal injury
Authors: Normahani Pasha , Boyle Joseph J. , Cave Luke , Brookes Paul , Woollard Kevin J. , Jaffer Usman
Published: March 2022

Background

Intermittent claudication (IC) is a common manifestation of peripheral arterial disease. Some patients with IC experience a rise in Urinary N-acetyl-β-D-Glucosaminidase (NAG)/ Creatinine (Cr) ratio, a marker of renal injury, following exercise. In this study, we aim to investigate whether peripheral blood mononuclear cells (PBMC) from patients with IC who exhibit a rise in urinary NAG/ Cr ratio following exercise exhibit differential IL-10/ IL-12 ratio and gene expression compared to those who do not have a rise in NAG/ Cr ratio.

Methods

We conducted a single center observational cohort study of patients diagnosed with IC. Blood and urine samples were collected at rest and following a standardised treadmill exercise protocol. For comparative analysis patients were separated into those with any rise in NAG/Cr ratio (Group 1) and those with no rise in NAG/Cr ratio (Group 2) post exercise. Isolated PBMC from pre- and post-exercise blood samples were analysed using flow cytometry. PBMC were also cultured for 20 hours to perform further analysis of IL-10 and IL-12 cytokine levels. RNA-sequencing analysis was performed to identify differentially expressed genes between the groups.

Results

20 patients were recruited (Group 1, n = 8; Group 2, n = 12). We observed a significantly higher IL-10/IL-12 ratio in cell supernatant from participants in Group 1, as compared to Group 2, on exercise at 20 hours incubation; 47.24 (IQR 9.70–65.83) vs 6.13 (4.88–12.24), p = 0.04. 328 genes were significantly differentially expressed between Group 1 and 2. The modulated genes had signatures encompassing hypoxia, metabolic adaptation to starvation, inflammatory activation, renal protection, and oxidative stress.

Discussion

Our results suggest that some patients with IC have an altered immune status making them ‘vulnerable’ to systemic inflammation and renal injury following exercise. We have identified a panel of genes which are differentially expressed in this group of patients.

Faktor Fisik dan Non Fisik yang Memengaruhi Aksesibilitas secara Perseptual dan Aktual terhadap Taman Monas, Jakarta
Authors: Rizkia Nadhira Putri , Setiawan Rulli Pratiwi
Published: March 2022

Monas park as the biggest urban park in Jakarta has various social, economic, and environmental benefits for its visitors. These benefits can be acquired if the park is accessible to the community. Previous research found that there are differences between visitor perception and the actual measured distances, where visitor perception is more important than measured distance. In addition, benefits gained by visitors can be more valuable than the accessibility cost of a park. This shows that if a park can provide benefits to the visitors, the visitors will not consider the accessibility cost as a burden. This research aims to find the factors affecting the visitors’ accessibility to Monas Park, in which the accessibility is measured based on perceptual and actual. This research involved active visitors who live in the Greater Jakarta area. The data were analyzed using Structural Equation Modelling Partial Least Square (SEM PLS) to find the factors affecting both perceptual and actual accessibilities. The results showed that security, transportation, and personal aspects affect perceptual accessibility, while park facilities and personal aspects affect the actual accessibility. Besides the physical factors, the non-physical factor such as leisure time availability also affects the perceptual and actual accessibilities to Monas Park.

Perum Perumnas which was formed by the Central Government in providing housing for low-income groups of people, made a design with a uniform minimum standard, which in the end the house in a certain period of time will experience changes made by residents. Both the house and the perumnas environment will continue to experience changes every year, this is due to the increasing number of population and the alternation of residents in the perumnas. To find out what changes have occurred in Perumnas Helvetia, data processing and analysis is carried out descriptively and using cross tabulation (crosstab). The results of data processing and analysis show that the building area is the change most often carried out by the occupants of the house. For the area of land / land there is no change. The type of house also affects changes in building area, which means that where the building area changes, the type of house will also change. As for other perumnas environments, roads are the changes that have changed the most in perumnas, ranging from width to pavement.change in the residential enviroment, national housing

Published: March 2022

In this study, the fatigue properties, microstructure, and surface damage tolerance of the 6N01 profile, 7N01 profile, and 7N01 plate aluminum alloy were studied. The fatigue test results show that the fatigue limit of the 7N01 profile was the highest and the 7N01 plate was the lowest. More importantly, most fatigue specimens failed in the safe life area provided by the Kitagawa–Takahashi line diagram, which indicates that there is a “short-notch effect” in the fatigue behavior of the pre-cracked aluminum alloys. For the sake of safety, according to the Kitagawa–Takahashi line diagram corrected by the fatigue test results, the effective harmless notch sizes a
0,eff of 6N01 profile, 7N01 profile, 7N01 plate is 23.92, 10.81, 24.32 μm, respectively, and their effective fatigue notch propagation threshold Δk
eff,th is 0.81, 0.39, 0.77 MPa m1/2, respectively. These corrected values reestablished the fatigue tolerance of the three materials and provided the critical data reference for the practical application. Combined with this study and the analysis of the literature, it can be concluded that the short-notch effect of the three materials should be related to the microstructure, crack closure mechanism, internal defects.
Sirens of Modernity: World Cinema via Bombay
Authors: Sunya Samhita
Published: March 2022

By the 1960s, Hindi-language films from Bombay were in high demand, not only for domestic and diasporic audiences, but for sizable non-diasporic audiences across Eastern Europe, Central Asia, the Middle East, and the Indian Ocean world. Confounding critics who saw the films as noisy and nonsensical, Bombay films attracted worldwide viewers precisely for their elements of romance, music, and spectacle. In this richly documented history of 1960s Hindi cinema, Samhita Sunya historicizes the emergence of world cinema as a category of cinematic diplomacy that formed in the crucible of the Cold War. Interwoven with this history is an account of the prolific transnational circuits of popular Hindi films. By following archival leads and threads of argumentation within commercial Hindi films that seem to be odd cases—flops, remakes, low-budget comedies, and prestige productions—this book offers a novel map for excavating the historical and ethical stakes of world cinema and world-making via Bombay.
Possibility of using waste edible oil for biogas production
Authors: Kolbl Repinc Sabina
Published: March 2022

Anaerobic digestion is a process by which energy from organically degradable waste can be recovered in the form of biogas. The uncontrolled disposal of such organic waste is very burdensome to the environment. In Slovenia, large quantities of waste edible oils are produced every year, which could be used for biogas production. In this study, we investigated the methane potential of waste edible oil in a batch reactor. Further in the pilot scale in a semi-continuous experiment we evaluated the use of waste edible oil in anaerobic digesters of wastewater treatment plant. The results show that the quantity of oil per day that is fed into the anaerobic reactor is limited due to the process's instability and lower biogas production. The optimal daily organic loading of waste edible oil was between 1.6 and 2.4 g VS/L inoculum. During these conditions, the process of anaerobic digestion was stable and methane production was highest. At higher organic loading, the process became unstable, pH was reduced, volatile fatty acids increased, COD at the outflow of reactor increased, and biogas production was significantly reduced.

Menurut Peraturan Menteri Pendayagunaan Aparatur Negara No. 2/PER/MENPAN/2/2008 dan Peraturan Menteri Pertanian No. 35/Permentan/OT.140/2009, membuat karya tulis bagi penyuluh pertanian merupakan kewajiban. Dengan menghasilkan karya tulis ilmiah, penyuluh memperoleh angka kredit sebagai upaya meningkatkan kinerja jabatan. Namun, kegiatan menulis masih merupakan hal yang sulit bagi penyuluh dan belum dirasa penting bagi mereka. Hal ini dikarenakan, mereka tidak percaya diri untuk menulis dan belum mengetahui kiat dan teknik penulisan karya ilmiaha. Untuk itu maka dipandang perlu adanya kegiatan berupa pelatihan penulisan karya ilmiah dan jurnalistik bagi petugas penyuluh pertanian untuk mendukung peningkatan kinerja dan kualitas penyuluhan mereka kepada publik dan petani binaan. Tim pengabdian kepada masyarakat Fakultas Ilmu Sosial Unnes memberikan solusi atas permasalahan tersebut dengan memberikan pelatihan menulis karya ilmiah dan jurnalistik bagi para penyuluh pertanian di lingkungan kabupaten Kendal. Bertempat di kantor Balai Penyuluhan Pertanian (BPP) Boja, tim pengabdi menghadirkan dua narasumber yang menyampaikan materi tentang kiat penulisan artikel jurnal dan popular di media massa. Sebanyak 24 peserta sangat antusias mengikuti pelatihan ini karena merupakan pertama kalinya bagi mereka memperoleh materi kepenulisan. Pelatihan ini dirasa sangat bermanfaat bagi mereka dalam meningkatkan kapasitas mereka sebagai penyuluh pertanian. Tidak hanya pengetahuan, namun juga peluang untuk memperoleh kredit poin dari karya tulis. Bahkan, para penyuluh menghendaki adanya tindak lanjut dari pelatihan ini kedepannya.

Purpose: Cervical cancer is one of the most common types of cancer that kills women worldwide. One way for early detection of cervical cancer risk is by looking at human behavior determinants. Detection of cervical cancer based on behavior determinants has been researched before using Naïve Bayes and Logistic Regression but has never using ADALINE Neural Network. Methods: In this paper, ADALINE proposes to detect early cervical cancer based on the behavior on the UCI dataset. The data used are 72 data, consisting of 21 cervical cancer patients and 51 non-cervical cancer patients. The dataset is divided 70% for training data and 30% for testing data. The learning parameters used are maximum epoch, learning rate, and MSE. Result: MSE generated from ADALINE training process is 0.02 using a learning rate of 0.006 with a maximum epoch of 19. Twenty-two test data obtained an accuracy of 95.5%, and overall data got an accuracy value of 97.2%. Novelty: One alternative method for early detection of cervical cancer based on behavior is ADALINE Neural Network.

Purpose: Currently, many fake certificates or diplomas are used to apply for jobs to get a better paying job. With that said, currently certificates cannot prove a person's expertise or skills. However, some students have implemented a Blockchain system in securing their certificates so that data manipulation is minimized, but only partially. Therefore, this research aims to motivate anyone, especially students in this Blockchain system and students will get incentives from all activities that are followed by racing in Blockchain gamification concept 4.0. Study design: This study uses the Pieces method to classify a problem (problem), opportunities (opportunities), and existing directions. Data collection techniques used primary data obtained by distributing questionnaires in the form of google form to respondents by involving students (n = 1129). Conclusions were analyzed with the SUS trial using a Likert scale with the cut and SUS method. Result: The results of this study are expected to Gamification in the system Blockchain can run optimally in implementation. The use of Gamification on the Alphabet Blockchain is included in the acceptable category. Value: The platform can check certificates that are not genuine.

“Hold the stars”: trayectoria y legado político de Eulalia Bernard Little
Authors: Muñoz-Muñoz Marianela
Published: March 2022

El artículo analiza la figura de Eulalia Bernard Little (1935-2021) como precursora de la representación de las mujeres afrocostarricenses en los espacios de decisión y gestión pública e internacional. A partir de archivos visuales y escritos y mediante el empleo de una metodología interdisciplinaria, que combina el análisis del discurso y la etnografía, se examina su condición de pionera en el campo político negro, dentro y fuera de Costa Rica. En primer lugar, se explora su consolidación como activista de la diáspora durante la década de los 70, desde la relación entre sus mismas experiencias de circulación afro-circuncaribeñas y su participación en escenarios de reflexión y discusión política y cultural. Seguidamente, se considera su incursión en los cuadros partidistas nacionales y el alcance de transformación social de su discurso. Finalmente, se identifica su influencia en la participación de otras mujeres afrocostarricenses situadas en la esfera política y político-cultural. La lectura de esta otra faceta de Bernard Little complementa los trabajos sobre su producción literaria, a la vez que amplía los estudios e historiografía de la comunidad afrocostarricense.
Memoria, identidad y utopía en los procesos de autorepresentación de las poetas afrocentroamericanas
Authors: Meza-Márquez Consuelo
Published: March 2022

La presencia de las escritoras afrodescendientes se visibiliza a partir de las últimas décadas del siglo XX. Es un discurso que surge de la  experiencia de discriminación por etnia y género y se constituye como un movimiento de resistencia cultural que recupera personajes emblemáticos, símbolos, imágenes, sueños e ideales que permiten la permanencia de la etnia en los distintos países. Tiene sus orígenes, con escritoras creoles, en Costa Rica con Eulalia Bernard (1935), Prudence Bellamy Richard (1935), Marcia Reid Chambers (1950), Shirley Campbell (1965),  Delia McDonald (1965) y Queen Nzinga Maxwell (1971). Le darán continuidad en Nicaragua, las escritoras June Beer (1935-1986), Erna Loraine Narcisso Walters (1942), Grace Kelly Bent, Annette Fenton (1973), Yolanda Rossman (1961), Deborah Robb Taylor (1965), Nydia Taylor (1953) y Andira Watson (1977); y en Panamá, Eyra Harbar y Melanie Taylor. Respecto a las escritoras garífunas, en Honduras se encuentra Xiomara Mercedes Cacho Caballero (1968), en Nicaragua, Isabel Estrada Colindres (1953) y en Guatemala, Nora Murillo (1964). Esta comunicación realiza un recorrido muy breve de una selección de autoras, no son todas, imposible agotarlas, pero si brinda el sentido y continuidad de esa importante tradición escritural.

The air we breathe contains suspended dust particles which can host filamentous fungi that can cause respiratory problems and allergies in humans. Generally, the propagules can survive depending upon the environmental conditions, such as humidity, temperature and cleanness. The aim of this research work was to detect the fungi in dust of outdoor air at the city of Morelia, Mich, México. So far similar study is not reported in this city. For this purpose, the samples were collected at fixed places from October to December 2017 at two times during the day. Results demonstrate the existence of the various fungi genera, from high to low concentration levels: Aspergillus fumigatus, Penicillium sp, A. niger, Monilia sp, Alternaria sp, Mucor sp, Acremonium sp Cladosporium sp, and Chrysosporium sp including more than one genus of yeasts such as Candida tropicalis and Rhodotorula rubra were isolated from the dust precipitated from the outside air, regardless of the intensity of solar radiation The existence of A. fumigatus and C. tropicalis represents a risk for human population who lives in this city in that sense a sanitary measures should be apply.

Context: Ocular trauma is the leading cause of monocular visual impairment around the world, especially in developing countries like Mexico. Great part of this cases occurs in pediatric and young adult groups. Epidemiology can vary depending on the population studied, but different factors such as socioeconomic status, occupation, sport and other activities have a great influence. Approximately 30% to 40% of ocular blindness cases in the world is due to ocular trauma, and of these, between 80 and 90% of events are preventable.1,2 Objective: The aim of this paper is to expose the importance of an individualized and damage-oriented repair plan in the scenario of a penetrating ocular trauma and serve as a treatment guideline in similar cases. Method: A case report of a 15 year-old male with right eye open globe injury with metal cable tip causing a penetrating corneal injury, posterior capsule rupture, lens opacity and vitreous hemorrhage Conclusion: The present case report illustrates the diverse ways of presentation that can be found when managing a penetrating ocular trauma. Our patient history is a good example of extended ocular involvement including cornea, lens, vitreous and retina. Individualized and damaged oriented surgical treatment is key in ocular trauma scenarios.
