Ants’ diversity (Hymenoptera-Formicidae) in the Algeria’s humid forests, case of the Gerrouche forest massif (Taza National Park)
Authors: Henine-Maouche Anissa , Tahraoui Abderrezak , Moulai Riadh
Published: August 2020

In order to contribute to the myrmecological fauna knowledg of the Guerrouche forest massif based in northeastern Algeria. A study was conducted on three oak groves (Quercus suber, Q. canariensis and Q.afares). A total of 60 plots were surveyed by using four sampling methods (manual capture, bait, pitfall and Winkler). The inventory revealed 34 ants species belonging to 15 genus and 4 sub-families; Dolichoderinae, Formicinae, Myrmicinae and Ponerinae. Dispatch as follow,  22 species for Cork oak, 14 for Algerian oak and 17 for Afares oak. Myrmicinae dominate in Cork oak and in Algerian oak (82.83 and 81.23% respectively) while in the Afares oak, Formicinae are largely in the lead (68.54%). This study revealed an endemic species to Algeria (Aphaenogaster testaceo-pilosa ssp canescens), three endemic’ species to Algeria and Morocco (Camponotus laurenti, Messor antennatus ans Aphaenogaster foreli) and one endemic to Algeria and Tunisia (Bothriomymrmex decapitans). Comparison of the four sampling methods effectiveness, used reveals that it’s the bait (80.7% of the species total number harvested in the all stations) and manual capture (49.69% of the species total number harvested in the all stations), which allowed the capture of the largest number of species followed by pitfalls traps (31.64% of the species total number harvested in the all stations). The Winkler was much less effective (5.55% of the species total number harvested in the all stations).
Noise-free quantitative phase imaging in Gabor holography with conditional generative adversarial network
Authors: Moon Inkyu , Jaferzadeh Keyvan , Kim Youhyun , Javidi Bahram
Published: August 2020

This paper shows that deep learning can eliminate the superimposed twin-image noise in phase images of Gabor holographic setup. This is achieved by the conditional generative adversarial model (C-GAN), trained by input-output pairs of noisy phase images obtained from synthetic Gabor holography and the corresponding quantitative noise-free contrast-phase image obtained by the off-axis digital holography. To train the model, Gabor holograms are generated from digital off-axis holograms with spatial shifting of the real image and twin image in the frequency domain and then adding them with the DC term in the spatial domain. Finally, the digital propagation of the Gabor hologram with Fresnel approximation generates a super-imposed phase image for the C-GAN model input. Two models were trained: a human red blood cell model and an elliptical cancer cell model. Following the training, several quantitative analyses were conducted on the bio-chemical properties and similarity between actual noise-free phase images and the model output. Surprisingly, it is discovered that our model can recover other elliptical cell lines that were not observed during the training. Additionally, some misalignments can also be compensated with the trained model. Particularly, if the reconstruction distance is somewhat incorrect, this model can still retrieve in-focus images.
Black phosphorus terahertz sensing based on photonic spin Hall effect
Authors: Zhu Wenguo , Xu Huanqi , Pan Jintao , Zhang Shuang , Zheng Huadan , Zhong Yongchun , Yu Jianhui , Chen Zhe
Published: August 2020

A novel terahertz (THz) sensing scheme is proposed based on the photonic spin Hall effect (PSHE). By illumining a paraxial Gaussian THz beam onto a black phosphorus (BP)-based Tamm structure, the reflected beam will undergo in-plane spin splitting, i.e., the centroids of two opposite spin components separate spatially. Due to Tamm plasmon resonance, one of the spin components is very sensitive to the refractive index changes of the analyte layer sandwiched by monolayer BP and distributed Bragg reflector. The sensitivity of the spin-dependent shift can be up to 2804 mm/RIU with a refractive index resolution of ∼10−8 RIU. The sensitivity and dynamic sensing region can be flexibly tuned by the BP rotation angle, thickness of analyte layer, or operation frequency. Therefore, the proposed PSHE-based THz sensing provides a new avenue for the development of high-performance THz sensors; thus, we may find applications in chemical sensing and biosensing.
Broadband dispersionless topological slow light
Authors: Chen Jianfeng , Liang Wenyao , Li Zhi-Yuan
Published: August 2020

We present a scheme to realize topological slow-light state with low
group velocity and vanishing group velocity dispersion. By harnessing
the strong interactions between two regular co-propagating topological
photonic states in a magneto-optical photonic crystal waveguide, the
energy flux transport of light exhibits a peculiar eight-shaped
flowing loop within each unit cell of the waveguide. This permits the
broadband pulse transporting with low group velocity (

n
g

=

13.26

), broad bandwidth with a relative
bandwidth of 3.08%, large normalized delay-bandwidth product (about
0.409), and vanishing group velocity dispersion. More importantly,
they are robust against backscattering from obstacles. Our scheme
paves the way to dig into the concept and physics of topology for
solving the difficult problems of signal distortion and scattering
loss in slow-light systems.
Accurate near-field millimeter-wave imaging of concave objects using multistatic array
Authors: Liang Bingyuan , Shang Xiaozhou , Zhuge Xiaodong , Miao Jungang
Published: August 2020

This paper discusses near-field imaging of complex objects under multistatic array configurations. Due to high-order scattering from concave surfaces, severe artifacts are often encountered when imaging high-contrast complex targets, which makes it difficult for applications that require accurate near-field imaging and recognition. Furthermore, concave objects often exhibit strong scattering directivity, which requires complete multistatic measurements in order to deliver accurate surface reconstructions. In this paper, accurate imaging of concave objects using multistatic array is investigated. An analytical forward model for dihedral-type concave objects are formulated using shooting and bouncing rays (SBR) principle and further used to create a new reconstruction algorithm for accurate multistatic imaging. The mechanism of multiple reflections under multistatic configurations and the formation of artifacts are also analyzed. Numerical simulations and experimental results are presented to demonstrate the correctness of the proposed forward model and the performances of the proposed imaging algorithm.
Prevalence and risk factors of bovine viral diarrhea in Colombian cattle
Authors: Ortega Diego Ortiz , Martínez Rodrigo , Tobón Torreglosa Julio César , Rocha Juan Felipe
Published: August 2020

Background and Aim: Bovine viral diarrhea virus (BVDV) is present in most cattle-raising countries around the world, and it has a negative economic impact in cattle herds. In Colombia, previous studies have estimated the prevalence of BVDV in specific locations. The aim of this study was to estimate the prevalence of BVDV in cattle herds located at several municipalities across the country and to identify the associated risk and protective factors. Materials and Methods: A cross-sectional study was carried out to investigate the prevalence of BVDV in Colombian cattle populations at farm and animal-levels. A total of 387 herds and 8110 animals located in seven different departments were included in this study. Results: An animal- and farm-level prevalence of 36% and 69%, respectively, were estimated. A high variation for the farm-level prevalence was found among the municipalities studied. Moreover, seropositive cattle to the infectious bovine rhinotracheitis virus (odds ratio (OR)=2.38, p=0.0479) and Neospora caninum (OR=3.15, p=0.0122) were more likely to be seropositive for BVDV, while the practice of burning dead animals at the farm was identified as a protective factor (OR=0.17, p=0.014). Conclusion: The prevalence of BVDV varied more at farm-level compared to animal-level. Two risk factors and one protective factor were identified. The results of the current study are essential to understand the epidemiology of BVDV in Colombia, and to formulate strategies in the region to mitigate the impact of this virus on the productive and reproductive indicators of cattle farms at the regional level.
Undervaluing the Right to an Interpreter: How Societal and Judicial Interests Threaten the Fairness of Multilingual Criminal Proceedings
Authors: Dingfelder Stone John
Published: August 2020

By its very nature, the right to a fair trial involves a balancing of competing interests. This paper examines how such a balancing process has undermined one particular fair trial right: the right to an interpreter under international law. In order to do so, the paper sets out the current contours of the right, highlighting and analysing the numerous trade offs that have been made in its development. The resulting analysis concludes that courts often prioritize judicial efficiency and economic frugality at the expense of the right to an interpreter with little or no understanding of the impact these decisions have on the effectiveness of the right. The end result is a balance that neuters the practical application of the right and undermines the fairness of criminal proceedings involving defendants who do not speak the language of the court.
Summary of Accurate and Precise Head Impacts Collected On-Ice in Hockey Players and How These Data Will be Used to Improve Equipment and Rules for Safer Play
Authors: Bartsch Adam J. , Benzel Edward C. , Samorezov Sergey , Miele Vincent J.
Published: August 2020

In this study, we used a laboratory-calibrated impact monitoring mouthguard (IMM) system and video review to document the presence of 77 potential blunt and inertial head impacts across 291 athlete exposures in ice hockey players aged 14 to 18. Our rate of impacts per athlete exposure was one to two orders of magnitude lower than prior studies, and we did not measure any high gravity impacts in the range 100 g to 200 g. We found four cases where the athlete sustained a “No-Go” impact per the National Football League (NFL) video review criteria. The No-Go cases were of similar impact dose severity and direction with No-Go athletes in American football and combat sport. We also measured a high-energy frontal impact dose that resulted in no visible impairment, and this also was on par with visibly normal athletes in American football and combat sport studied previously. The inertial and blunt impact time trace data collected in this study give a full six-degrees-of-freedom kinematic profile of true ice hockey head impacts measured in the “living laboratory.” This detailed knowledge, for the first time, permits creation of helmet tests per the on-ice exposures where designs can acutely focus on reducing impact energy dose. Assuming skull fracture risks have been sufficiently minimized, reduction of energy transfer to the brain in side and rear impacts should be the paramount design considerations. We suggest that for players to be monitored using a mouthguard-based system, coaches and referees must enforce current safety rules on mouthguard use during play. Stringent enforcement of rules against checking from behind would help further reduce instances of the already rare No-Go impacts. And while relatively few impacts occurred in our ice hockey population, it would be prudent to investigate effects of cumulative impact dosing in a broader set of athletes longitudinally.
ТЕНДЕНЦІЇ РОЗВИТКУ ТА ПЕРСПЕКТИВИ ТОРГОВЕЛЬНО-ЕКОНОМІЧНОГО СПІВРОБІТНИЦТВА МІЖ КИТАЄМ ТА УКРАЇНОЮ
Authors: ДУН’ЯН Чжан
Published: August 2020

Розглянуто стан і перспективи розвитку торговельно-економічних відносин України та Китаю. Доведено, що двостороннє співробітництво в торговельно-економічній сфері досягло значного прогресу. В період 2012–2017 рр. Китай був другим після Росії найбільшим торговельним партнером України. Однак проблему дисбалансу в імпорті та експорті між Україною і Китаєм досі не вирішено. Крім того, масштаб і кількість проектів, у яких Україна залучає китайські інвестиції, набагато менші, ніж стосовно інвестицій з європейських країн і США.Обгрунтовано, що торговельно-економічне співробітництво між Україною і Китаєм перебуває на новому історичному етапі. З одного боку, Україна підписала угоду з Європейським Союзом про асоціацію, і з 1 січня 2016 р. набули чинності правила зони вільної торгівлі між Україною та ЄС, що допомагає прискорити інтеграцію української економіки в європейську. З іншого боку, глобальний економічний спад вимагає впровадження інновацій у моделі співпраці. Китайська ініціатива «Один пояс – один шлях» – це один з варіантів інноваційної моделі співробітництва. Її значення полягає в об'єднанні Азіатсько-Тихоокеанського регіону з ЄС з метою приєднати Євразійський економічний союз, створити новий простір і можливості для розвитку та досягти спільного з євразійськими країнами процвітання. Усе це формує безпрецедентні можливості для розвитку двосторонніх економічних і торговельних відносин.Звісно ж, що для повного розкриття потенціалу економіки України та розширення двостороннього торговельно-економічного співробітництва необхідно враховувати такі пропозиції, як створення китайсько-українського індустріального парку, сприяння співробітництву в галузі електронної торгівлі, формування китайсько-української зони вільної торгівлі, розширення взаємодії в межах багатосторонніх механізмів (наприклад, Шанхайської організації співробітництва та взаємодії Китаю і країн Центральної та Східної Європи у форматі «16 + 1»).
Sunni and Shiite Political Thought of Islam State Relationship: A Comparison between Abdurrahman Wahid of Indonesia and Ayatollah Khomeini of Iran
Authors: Nurdin Ahmad Ali , Kharlie Ahmad Tholabi
Published: August 2020

This paper discusses how the Indonesian Sunni Muslim leader Abdurrahman Wahid and the Iranian Shiite Muslim leader Ayatollah Khomeini responded to the debate about the relationship between Islam and the state. Their responses impacted on the struggle of Indonesian and Iranian Muslims in considering the ideological basis of Indonesian and Iranian states. On the one hand, Wahid with his educational and social background and Indonesian political context rejected the concept of an Islamic state. He did not agree with the formalization of Islamic sharia. To implement his idea, he promoted the idea of Pribumisasi Islam. For Wahid, islamization was not arabization. Khomeini, on the other hand, believed that Islam is a religion that has complete laws and way of life including social rules. According to Khomeini, to effectively implement these rules, Muslims need to have executive power. In Khomeini’s view, when the Quran calls for Muslims to obey Allah, the messenger, and ulil amri, this means that Allah instructs Muslims to create an Islamic state. To realise his views, Khomeini proposed the doctrine of Velayat-e al Faqeeh. Thus, different religious-political contexts of these two leaders contributed to their different responses to the relationship between Islam and the state.
The Roma in Post-Communist Bulgaria: Growing Social Marginalization and State Policies
Authors: Christidis Yorgos
Published: August 2020

This article analyzes the growing impoverishment and marginalization of the Roma in Bulgarian society and the evolution of Bulgaria’s post-1989 policies towards the Roma. It examines the results of the policies so far and the reasons behind the “poor performance” of the policies implemented. It is believed that Post-communist Bulgaria has successfully re-integrated the ethnic Turkish minority given both the assimilation campaign carried out against it in the 1980s and the tragic events that took place in ex-Yugoslavia in the 1990s. This Bulgaria’s successful “ethnic model”, however, has failed to include the Roma. The “Roma issue” has emerged as one of the most serious and intractable ones facing Bulgaria since 1990. A growing part of its population has been living in circumstances of poverty and marginalization that seem only to deteriorate as years go by. State policies that have been introduced since 1999 have failed at large to produce tangible results and to reverse the socio-economic marginalization of the Roma: discrimination, poverty, and social exclusion continue to be the norm. NGOs point out to the fact that many of the measures that have been announced have not been properly implemented, and that legislation existing to tackle discrimination, hate crime, and hate speech is not implemented. Bulgaria’s political parties are averse in dealing with the Roma issue. Policies addressing the socio-economic problems of the Roma, including hate speech and crime, do not enjoy popular support and are seen as politically damaging.

marcas múltiples oportunidades de interacción con sus consumidores. En cuanto

al tiempo de uso, se destacan las apps de redes sociales y mensajería

instantánea, representando más del 50% del tiempo total de uso diario de los

smartphones. Para abordar este fenómeno, la investigación del consumidor se ha

enfocado principalmente en el proceso de adopción de estas soluciones móviles,

destacándose la aplicación del modelo de aceptación de la tecnología. Por otra

parte, se ha investigado la experiencia del usuario a través de la combinación de

técnicas como el customer journey mapping y el eye tracking. Esto ha permitido

explorar el proceso de compra de los usuarios en apps de comercio,

principalmente en categorías de vestuario y calzado. Otro hallazgo relevante para

las marcas consiste en las importantes diferencias que se han encontrado a nivel

de usabilidad y valor percibido entre la página web y la app móvil de un mismo

servicio. Se requiere entonces un minucioso estudio durante la fase de desarrollo

de la app, para adaptar el contenido, las herramientas y la usabilidad de acuerdo

al perfil y las expectativas del segmento de consumidores que se busca atraer.

Finalmente, el estudio de la adopción, uso y valor percibido por parte de los

Las necesidades energéticas de un país, en conjunto con la forma en la ellas se suplen, determinan en gran medida las posibilidades de desarrollo que tiene el mismo. Sin embargo, no basta con simplificar el problema a un balance entre oferta y demanda energética, sino que un análisis en donde se contemple el tipo de fuentes y usos que se le dé a la misma permite identificar fortalezas en varios frentes, así como también la detección de alertas que pueden contribuir a atender carencias que enfrentan algunos sectores de la sociedad, a través del refinamiento de políticas que surgen de los tomadores de decisiones.
BLUE OCEAN STRATEGY: A marketing theory to create uncontested market space and make the competition irrelevant
Authors: Ganguly Kaushik Kumar
Published: August 2020

In the 21st century the world is changing; dramatic shifts in technology and the global marketplace are having a profound impact on organizations. Whether they operate in the private, public or non-profit sectors, organizations in every continent need to rethink the way they do business.Organizations
can no longer afford to build a strategy on existing environmental and industry conditions, but instead shape them in their favour.

Blue Ocean Strategy is a marketing theory by W. Chan Kim and Renée Mauborgne, professors at INSEAD Business School, in their 2005 book
- Blue Ocean Strategy.Based on a study of 150 strategic moves spanning more than a hundred years and thirty industries, Kim and Mauborgne argue that companies can succeed by creating "blue oceans" of uncontested market space, as opposed to "red oceans" where competitors
fight for dominance. They assert that these strategic moves create a leap in value for the company, its buyers, and its employees while unlocking new demand and making the competition irrelevant

Using Disruptive Innovation for Disaster Mitigation and Ensuring Supply Chain Continuity
Authors: Chattopadhyay Shouvik
Published: August 2020

Supply chains are a network of intertwined nodes and routes that are normally expected to operate smoothly and allow for seamless movement of material, documentation and information two and fro its entirety. Such large networks spread over a wide area on a global scale are bound
to be affected by disruptive factors both natural as well as man-made.

Though some amount of research has been done on supply chain disruption, mitigation efforts, risk management, etc. a proper linkage is normally missing. Also very little research has been done on continuity. This
paper does a selective literature review of selected papers covering various areas of supply chain disruption management under exogenous shock conditions like natural disasters and solutions and links the recent innovation of drone technology to disaster recovery and mitigation efforts and
ensuring supply chain continuity. While commercial drones are under test usage by variety of organizations, this paper also assesses certain selected drone types for their compatibility and future modified usage in disaster recovery and supply chain continuity after natural disasters.
The Analysis of Sub-Communities Behavior in Social Networks
Authors: Alsmadi Izzat , Easttom Chuck
Published: August 2020

Clique relations are useful in understanding the dynamics of a wide range of social interactions. One application of studying clique relations involves studying how such “detection of abnormal cliques’ behaviors” can be used to detect sub-communities’ behaviors
based on information from Online Social Networks (OSNs).In social networks, a clique represents a sub-group of the larger group in which every member in the clique is directly associated with every other member in the clique. Those cliques often possess a containment relation with each
other where large cliques can contain small size cliques. Thus, finding the extent of the clique, or the maximum clique is an important research questions. In our approach, we evaluated adding the weight factor and integrating graph theory to clique algorithm in order to derive more data about
the clique. In this regard clique activities are not like those in group discussions where an activity is posted by one user and is visible by all others. Our algorithm calculates the overall weight of the clique based on individual edges. Users post frequent activities. Their clique members,
just like other entities, may or may not interact with all those activities.
Behavioral-based malware clustering and classification

Published: August 2020

Detection of malwares and security attacks is a complex process that can vary in its details, analysis activities, etc. As part of the detection process, malware scanners try to categorize a malware once it is detected under one of the known malware categories (e.g. worms, spywares,
viruses, etc.). However, many studies and researches indicate problems with scanners categorizing or identifying a particular malware under different categories. There are different reasons for such challenges where different malware scanners, and sometime the same malware scanner, will categorize
the same malware under different categories in different times or instances. In this paper, we evaluated this problem summarizing existing approaches on malware classification.

Published: August 2020

In this paper, we present a new swarm intelligence algorithm for gene selection called quantum moth flame optimization algorithm (QMFOA), which based on hybridization between quantum computation and moth flame optimization algorithm (MFOA). The purpose of QMFOA is to identify a small
gene subset that can be used to classify samples with high accuracy. The QM- FOA has a simple two-phase approach, the first phase is a pre-processing that uses to address the difficulty of high-dimensional data, which measure the redundancy and the relevance of the gene, in order to obtain
the relevant gene set. The second phase is hybridization among MFOA, quantum computing, and support vector machine (SVM) with leave-one-out cross-validation (LOOCV), in order to solve the gene selection problem. The main objective of the second phase is to determine the best relevant gene
subset of all genes obtained in the first phase.In order to assess the performance of the proposed QMFOA, we test it on six Microarray datasets. Experimental results show that QMFOA provides great classification accuracy in comparison to some known algorithms.
Gorter-Casimir two fluid model revisited and possible applications to superconductivity
Authors: Pal Soumyadipta , Ganguly Koyel , Basu Arnab , Sharma Uma D.
Published: August 2020

In this paper, Gorter-Casimir (GC) two fluid model for low temperature normal superconductors is modified introducing phononic term along with electronic term in the normal phase free energy. The exponent corresponding to the normal phase fraction is changed from 1/2 to a general value
n which can be different for different materials. n is a parameter which tunes how much portion of normal phase free energy will be reduced to form superconducting phase by condensation of normal electrons into super-electrons at some finite temperatures below superconducting
transition temperature (TC) and the electron-phonon interaction is the controlling factor which calibrate the values of n. This present model describes the idea of different jump ratios of specific heat of different materials at T = TC, which GC model cannot predict.
We have adopted a new concept of “Phase diagram” from which an idea of a new temperature T* has been obtained. Modified GC model explains well the resistivity behavior near TC. Moreover, for some high temperature superconductors along with the electronic and
phononic contribution, a low temperature Schottky contribution is added to the free energy density. However, the contribution is negligible near TC.
A Green Solution To Cold Storage Using Magnetic Refrigeration System
Authors: Chatterjee Satyaki , Bhargow Amulayan
Published: August 2020

In the last few decades the wastage of food items is due to insufficient cold storage facilities in India. This is largely due to the high electricity costs of vapor compression refrigeration cycles. This has prompted to use the alternate refrigeration cycles. This paper is devoted
to using magneto-caloric effect of ferromagnetic materials for maintaining the temperature about 280K so as to keep the perishable items preserved for some period of time. The main objective of this type of refrigeration is use of solid refrigerant called magneto caloric material. This type
of material can increase or decrease the temperature when they are magnetized or demagnetized. Magnetic refrigeration systems are like traditional cooling units, but they don’t use as much electricity which make it highly efficient to be use for cold storage system. The effect of solid
state refrigerants, water based heat transfer fluids increases the efficiency with minimum contribution to global warming & ozone depletion making it highly sustainable which is the need of the hour.
Study on the Effect of Zinc Oxide Nanoparticles on Injection Barrier Height of Crystal Violet Dye Based Organic Device
Authors: Sen Sudipta , Baran Manik Nabin
Published: August 2020

Organic devices have achieved substantial progress due to its flexibility, cost effectiveness, simple processing and wide customizability. But there are certain limitations of these devices. One of the main limitations is the lower charge injection from metal electrodes to the organic
layer which affects the performance of these devices. The charge injection process is strongly dependent on the injection barrier height at metal- organic layer interface. Due to high barrier height at metal – organic layer interface, the charge injection is reduced at the interface.
Attempts need to be made to reduce the injection barrier height at metal – organic layer interface to improve the charge injection process. In the present work, we have studied the injection barrier height of Indium tin oxide coated glass/Crystal violet dye/Aluminium based organic device
and subsequently we have also observed the effect of zinc oxide nanoparticles on injection barrier height of this device. Indium tin oxide coated glass and aluminium are used as front electrode and back electrode respectively to form this device. The device has been prepared with and without
zinc oxide nanoparticles by using spin coating technique. We have analyzed the steady state current-voltage characteristics of the device to determine the barrier height of the device. Barrier height is reduced from 0.87 eV to 0.78 eV in the presence of zinc oxide nanoparticles. The barrier
height is also estimated by using another alternative method which is known as Norde method. By using Norde method, barrier height is measured which reduces from 0.83 eV to 0.77 eV in presence of zinc oxide nanoparticles. Both the methods show good consistency with each other. Reduction of
the injection barrier height in presence of zinc oxide nanoparticles indicates better charge injection through the metal - organic dye interface. The higher electron mobility of zinc oxide nanoparticles facilitates efficient charge injection at the interface. Thus, this work will be informative
to study the effect of zinc oxide nanoparticles on injection barrier height as it reduces the barrier height to improve the charge flow at metal – organic dye interface.
Quantum teleportation: a hypothetical concept
Authors: Datta Raktim , Chatterjee Suryakanta , Banerjee Ishan , Bose Debayan , Dutta Sneha , Basu Arnab
Published: August 2020

Quantum Teleportation is a hypothetical but logical application of Quantum Entanglement, which is basically a non-classical and strange phenomenon. It involves instantaneous communication between two very far situated particles through any non- perceivable link and can be considered
to communicate more than the speed of light, and this fact holds the power to stand against Einstein’s General Theory of Relativity. Here the ‘Hidden Variable Theory’ comes into play, and there is a synchronisation between the variables in such a way that leads to their communication.
But, whenever there is a simultaneous result from a particle in response to an event occurring on the other particle, it violates ‘The Principle of Locality’. Evidently, there has to be some connection through other spatial dimensions as predicted by the String Theory. It can also
be true that, entangled particles take shortcuts for communication across universe which is generally referred to ‘Space-time Wormholes’. Magnetic wormholes have been created till date by manipulating electromagnetic fields, but Space time wormholes are yet to be discovered. Logically,
such kind of wormholes can be created only by manipulating the mysterious ‘Gravitational Waves’ which possesses extraordinary characteristics of producing rhythmic but alternate expansion and compression in the Space-time fabric, of intensity equal to the frequency of the wave.
As these waves create distortion in space-time fabric, it results in change in the speed of light with respect to time. So it might be possible that entangled particles communicate at a speed higher than that of light which is beyond perception. It might also be possible that the universe
is ‘SuperDeterministic’.

the user is satisfied. With consideration to the Fisher-Yates algorithm, we don’t randomly select a song. Rather we aim to create a database where the songs are categorised and played according to the user’s choice.

Recently, dye sensitized photovoltaic cell plays an important role as a renewable source of energy because of low material cost, easy processing techniques. But the organic devices are prone to traps due to which charge carriers get trapped or recombined within the device before collection
at the electrodes. So traps limit the device performance. The study on the charge transport mechanism enables us to estimate this trap energy. In this work, we have designed the photovoltaic device and estimated the trap energy of inexpensive water-soluble Fuchsin dye based photovoltaic cells.
To design a photovoltaic device we have used ITO as a front electrode and copper as a back electrode. 540mg of TiO2 nanoparticles and 100mg of Fuchsin dye mixed well in N, N-Dimethyl formamide (DMF). A thin layer of this TiO2 nanoparticles and dye has been deposited between
two electrode using popular method named doctor’s blade method. A drop of electrolyte made of lithium percolate (LiClO4), ethylene carbonate (EC) and propylene carbonate (PC) solution has been used to obtain better device performance. The analysis of dark current density-
voltage (J-V) characteristics using exponential charge transport mechanism of this photovoltaic cell the trap energy has been calculated 0.5399 ± 0.006 eV. Also, we have observed photovoltaic effect of this device. Under illumination of 120 kLUX intensity, maximum short circuited current
density is obtained 4.62 μA/cm2 and open circuited voltage is 0.24 Volt.

Application of MEG in Increasing External Quantum Efficiency Over 100%
Authors: Kumar Shubham , Saha Kaustav
Published: August 2020

This review paper focuses on increasing the efficiency of Solar cell using Quantum Dot. The principle idea is using MEG (Multiple exciton Generation). MEG is more efficient in quantum confined nanostructures than in bulk semiconductors because the momentum preservation prerequisite
is relaxed. Even the carrier-carrier interactions are huge due to strong confinement. The carrier multiplication decoupling from the effective band gap allows amplified photo-voltage for corresponding carrier multiplication. Along with this, it was also found that external quantum efficiency
(EQE) would reach almost 100%, sometimes even exceeding it, for energy which is greater than twice the band gap energy. This is due to the fact that high energy photons have the ability to produce more than one photo carrier pair. MEG is definitely a promising route to increasing solar cell
efficiency. If a threshold of twice the band gap energy could be realized for impact ionization in a colloid Quantum Dot cell, the theoretical maximum possible conversion efficiency would shift to above 60%. The goal is to capture maximum energy incident on a given plane and targeting highyield
transportation of the resultant photo generated charge.

Published: August 2020

5-G stands for 5th generation. An upcoming technology in India which promises high speed and consistent internet. It might be available in India in 2019. Rapid increase in use of internet has put many demands which are beyond the reach of 4g like improved data rate, decreased latency,
less power consumption and better quality of service. To meet these measures a revolutionary step must be taken in the form of 5g. Our paper presents a comparative based study on 5g applications. 5g is expected to revolutionize the internet much more than Jio’s 4g did. Users will experience
high valued fast and powerful technology like never before. 5g technology will have extraordinary data capabilities and will have ability to tie together unrestricted call volumes and infinite data broadcast within latest mobile operating system. 5g technology will take over world market easily
in coming days. 5g technology will have an extraordinary capacity to support soft wares and consultancy. It will have endless benefits. It will help in visualization of universe, galaxies, planets and extra celestial bodies. It will take all delivery service out of business prospect. 5g technology
will be providing large broadcasting of data in gigabit. It will enhance many medical procedures.Now we all know there’s always another face of any coin. 5g technology will have some disadvantages too. Since 5g services are likely to run on ultra-high spectrum bands which travels
shorter distance compared with lower bands, they will be more suited to enhance indoor coverage. 5g technology will have higher frequency waves which could be blocked by buildings and might lose intensity over distance so it will be a tough challenge and will require large investments.In
conclusion, despite of some problems, 5g technology will be an innovation for mobile industry and will definitely change people’s life.
Scale-up effects in alkali-activated soil blocks

Alkali activation is a novel method of soil stabilisation, which could be used for the production of compressed blocks as walling materials. Given that much of the fundamental research into the chemical behaviour of this process has been done for small specimens, there is a knowledge gap over the potential effects of increasing specimen size. In this study, blocks were made from a mix of soil, sand and sodium hydroxide solution using a manual block press. Their phase composition and microstructure were investigated using powder X-ray diffraction and scanning electron microscopy; drying behaviour and compressive strength were also measured. No major microstructural or phase differences were found between the central and edge regions of the blocks. Longer curing time had little effect on phase formation and microstructure, but resulted in increased compressive strength. There are no fundamental chemical issues obstructing the scale-up of this stabilisation method, but further research should focus on the measurement of properties in line with building standards and eliminating hazards in the manufacturing process.
Effects of cross-section shape on cyclic lateral response of steel piles in residual soil

Published: August 2020

The lateral cyclic loaded piles' behaviour in bonded residual soil is still poorly understood by classical geotechnics. Currently used models reproduce the behaviour of residual soils based on those from other unstructured soils, resulting in a conservative design. This paper thus proposes to evaluate the behaviour of three different shapes of steel piles embedded in bonded residual soil when submitted to cyclic lateral loading tests. These tests encompassed 10 mm displacements performed on the top of the piles (considering service (working) displacements). The piles, with a length of 2·0 m, were equipped with strain gauges at ten levels. The evaluated cross-sections have circular, square and H shapes, all with similar inertia moment and diameter/edge of 0·15 m. The effect of cyclic loading has shown a degradation of available lateral load, mostly in the first 30 cycles. This degradation is also seen at the bending moments obtained. The piles have also shown a short free-headed behaviour that rotates from a certain depth. Finally, the study showed that the square cross-section-shaped pile had the best performance under service (working) cyclic displacements when embedded in bonded residual soil, followed by H cross-sectioned pile and finally the circular cross-sectioned pile.
A radical revision of the public health response to environmental crisis in a warming world: contributions of Indigenous knowledges and Indigenous feminist perspectives
Authors: Lewis Diana , Williams Lewis , Jones Rhys
Published: August 2020

Indigenous peoples have long been successful at adapting to climatic and environmental changes. However, anthropogenic climatic crisis represents an epoch of intensified colonialism which poses particular challenges to Indigenous peoples throughout the world, including those in wealthier ‘modern’ nation states. Indigenous peoples also possess worldviews and traditional knowledge systems that are critical to climate mitigation and adaptation, yet, paradoxically, these are devalued and marginalized and have yet to be recognized as essential foundations of public health. In this article, we provide an overview of how public health policy and discourse fails Indigenous peoples living in the colonial nation states of Canada and Aotearoa New Zealand. We argue that addressing these systemic failures requires the incorporation of Indigenous knowledges and Indigenous feminist perspectives beyond superficial understandings in public health-related climate change policy and practice, and that systems transformation of this nature will in turn require a radical revision of settler understandings of the determinants of health. Further, public health climate change responses that centre Indigenous knowledges and Indigenous feminist perspectives as presented by Indigenous peoples themselves must underpin from local to global levels.
