Primordial Black Holes And Gravitational Waves Based On No-Scale Supergravity

In this paper we present a class of models in order to explain the production of Primordial Black Holes (PBHs) and Gravitational Waves (GWs) in the Universe. These models are based on no-scale theory. By breaking the SU(2,1)/SU(2)×U(1) symmetry we fix one of the two chiral fields and we derive effective scalar potentials which are capable of generating PBHs and GWs. As it is known in the literature there is an important unification of the no-scale models, which leads to the Starobinsky effective scalar potential based on the coset SU(2,1)/SU(2)×U(1). We use this unification in order to additionally explain the generation of PBHs and GWs. Concretely, we modify well-known superpotentials, which reduce to Starobinsky-like effective scalar potentials. Thus, we derive scalar potentials which, on the one hand, explain the production of PBHs and GWs and, on the other hand, they conserve the transformation laws, which yield from the parametrization of the coset SU(2,1)/SU(2)×U(1) as well as the unification between the models which are yielded this coset. We numerically evaluate the scalar power spectra with the effective scalar potential based on this theory. Furthermore, we evaluate the fractional abundances of PBHs by comparing two methods the Press–Schechter approach and the peak theory, while focusing on explaining the dark matter in the Universe. By using the resulting scalar power spectrum we evaluate the amount of GWs. All models are in complete consistence with Planck constraints.
L-band femtosecond fiber laser with Cu2Te-PVA thin film

For the first time, this research proposed a copper telluride (Cu2Te)-polyvinyl alcohol thin film as a saturable absorber (SA) in an erbium-doped fiber laser (EDFL) operating in the long-wavelength band (L-band). The nonlinear optical absorption measurement of Cu2Te thin film revealed a saturation intensity of 3.26 kW cm−2 and a modulation depth of 2.7%. Furthermore, the mode-locked pulse was successfully generated by integrating a Cu2Te thin film into the L-band cavity at a threshold pump power of 135.61 mW with a center wavelength and pulse duration of 1565.48 nm and 770 fs, respectively. When observing the output mode-locked pulse, the pump power for the EDFL ranged from 135.61 mW to 201.28 mW, with the fundamental mode having a repetition rate 10.28 MHz. Furthermore, the magnitude of the signal-to-noise ratio was approximately 61.3 dB, indicating that the laser was stable with no significant fluctuations during the stability test. Overall, the findings showed that Cu2Te thin film has an excellent output and a promising candidate for an SA, implying that it could have a lot of potentials in pulsed laser application.
Unsupervised Machine Learning for the Identification of Preflare Spectroscopic Signatures

The study of the preflare environment is of great importance to understanding what drives solar flares. k-means clustering, an unsupervised machine-learning technique, has the ability to cluster large data set in a way that would be impractical or impossible for a human to do. In this paper we present a study using k-means clustering to identify possible preflare signatures in spectroscopic observations of the Mg ii h and k spectral lines made by NASA's Interface Region Imaging Spectrometer. Our analysis finds that spectral profiles showing single-peak Mg ii h and k and single-peaked emission in the Mg ii UV triplet lines are associated with preflare activity up to 40 minutes prior to flaring. Subsequent inversions of these spectral profiles reveal increased temperature and electron density in the chromosphere, which suggest that significant heating events in the chromosphere may be associated with precursor signals to flares.

Supervision of The Complement System by Toxoplasma During Neural Infections (Areview)

Chronic infections with Toxoplasma gondii occur in the brain of mammalian hosts. The understanding of the relationship between Toxoplasma gondii, CNS, and the immune system assists in comprehending how Toxoplasma affects the complement system and how it exerts a defense mechanism against Toxoplasma. This review focuses on the supervision of the complement system by Toxoplasma gondii during neural infections. There are three possible mechanisms by which the protozoan can invade the brain. Tachyzoites in bloodstreams multiply, invade, and bind to endothelial cells before migrating into parenchymas via transcellular crossing mechanisms. Secondly, the immune cells become like the Trojan horse, which carries intracellular parasites across the blood–brain barrier (BBB). In the third mechanical process, the BBB can directly be crossed through the brain at the tight junction (TJ) by the tachyzoites. It is concluded that C3 manipulation of the integrity of the BBB can be used to increase T.gondii invasion into the CNS.

The patterns of agroforestry: the implementation and its impact on local community income and carbon stock in Sesaot Forest, Lombok, Indonesia

This article aims to explore the implementation of agroforestry patterns in the Sesaot forest area and the impacts on the local community income and the carbon stocks. It is written based on descriptive research, data are collected through observation, interviews, and FGDs to 42 respondents, and measuring carbon stocks in 18 locations. The analysis in this study is divided into three: 1) clustering based on plant dominance to identify existing agroforestry patterns, 2) allometric equations to measure the amount of carbon stock, and 3) using scoring to analyze the identified agroforestry patterns to find out the most optimal. This study finds that there are four agroforestry patterns in this area: candlenut dominant, mahogany dominant, mixed agroforestry, and simple agroforestry. From these patterns, mixed agroforestry seems to be the best practice in this area since it has complied with the principles of sustainable forest management both from the perspective of economic and the environment.

High-speed A/D conversion incorporating a QMF bank

A structure for analog-to-digital (A/D) conversion capable of attaining high speed and using an array of lower-speed A/D converters is introduced. The structure is based on a quadrature mirror filter (QMF) bank, except that the analysis filter bank is a switched-capacitor circuit, whereas the synthesis filter bank is normally a digital circuit. It is shown that the effect of mismatches among the A/D converters in the array is considerably reduced by the QMF bank. Simulation and experimental results verifying the good performance of the proposed approach are included. >
Numerical Simulation of Shaking Table Test of Tianjin Transportation Junction

A shaking table test of large-scale pile-soil-complex structure interaction is accomplished on the transport hub of Tianjin station, and some reliable testing data of soil-structure dynamic interaction laws are acquired. ANSYS is used to simulate the process of the test, including establishment of 3D FEM model, selections of material parameters and constitutive, treatment of boundary conditions. Comparative analysis is performed between simulation data and testing data. The results show that: the simulative results agree well with the experimental ones under small earthquake, but the deviation increases when it suffers medium earthquake. The rationality of the numerical simulation and test are verified by each other, and the causes of the deviation under medium earthquake are analyzed.
Squint Hard Enough: Evaluating Perceptual Hashing with Machine Learning

Many online communications systems use perceptual hash matching systems to detect illicit ﬁles in user content. These systems employ specialized perceptual hash functions such as Microsoft’s PhotoDNA or Facebook’s PDQ to produce a compact digest of an image ﬁle that can be approximately compared to a database of known illicit-content digests. Recently, several proposals have suggested that hash-based matching systems be incorporated into client-side and end-to-end encrypted (E2EE) systems: in these designs, ﬁles that register as illicit content will be reported to the provider, while the remaining content will be sent conﬁdentially. By using perceptual hashing to determine conﬁdentiality guarantees, this new setting signiﬁcantly changes the function of existing perceptual hashing – thus motivating the need to evaluate these functions from an adversarial perspective, using their perceptual capabilities against them. For example, an attacker may attempt to trigger a match on innocuous, but politically-charged, content in an attempt to stiﬂe speech. In this work we develop threat models for perceptual hashing algorithms in an adversarial setting, and present attacks against the two most widely deployed algorithms: PhotoDNA and PDQ. Our results show that it is possible to eﬃciently generate targeted second-preimage attacks in which an attacker creates a variant of some source image that matches some target digest. As a complement to this main result, we also further investigate the production of images that facilitate detection avoidance attacks , continuing a recent investigation of Jain et al. Our work shows that existing perceptual hash functions are likely insuﬃciently robust to survive attacks on this new setting
A new method for extracting the channel-length reduction and the gate-voltage-dependent series resistance of counter-implanted p-MOSFETs

Based on the channel-resistance measurement, a new method for extracting the channel-length reduction (/spl Delta/L/sub jj/) and the gate-voltage-dependent source/drain resistance (R/sub SD/) of counter-implanted p-MOSFETs is proposed, in which the necessity of the applying substrate bias is demonstrated and an empirical relationship between poly-Si gate length (L/sub M/) and device structure parameters for /spl Delta/L/sub jj/ extraction is provided. This is the first attempt to extract the basic parameters of counter-implanted p-MOSFETs with the LDD structure. Numerical analysis using two-dimensional (2-D) device simulator has been used to verify the proposed extraction method. Furthermore, an improved approach to extract R/sub SD/ is also presented. Both numerical analysis and experimental results show good accuracy of our proposed method.
PHYSICOCHEMICAL CHARACTERISTICS AND GREEN MICROALGAE COMPOSITION OF SELECTED RIVERS IN OGUN STATE, NIGERIA

The river system is the most complex of the freshwater bodies in the world and is prone to pollution especially from anthropogenic activities and the quality of water, as partially determined by physicochemical properties, is very crucial for primary productivity in the aquatic environment. This study determined the physicochemical characteristics and green microalgae of water collected from Majopa, Ogunpa and Uren rivers in Ogun State, Nigeria. Surface water samples were collected from three different rivers using direct collection method into the labelled bottles for physicochemical characteristics determination, culturing and ecological studies. Water samples for ecological studies were fixed in 4% unbuffered formalin while sample for culturing were not fixed but growth stimulated using Bold Basal Medium (BBM) and BlueGreen Medium (BG-11). The physicochemical parameters varied widely with the profile of water sample from Ogunpa River being the most favourable for widest diversity of green microalgae of all three. The pH of the water samples were slightly acidic ranging between 6.3 and 6.5 for the rivers, while the lower dissolved oxygen (2.61-3.01 mg/L) recorded pointed to a stressed environment which probably accounted for lower number of microalgae taxa observed, especially in Majopa River. The ecological studies showed the presence of ten taxa from the division Chlorophyta with nine taxa from Ogunpa River and Scenedesmus sp. being dominant genus across the rivers. The microalgae diversity of the river water was Ogunpa River˃Uren River˃Majopa River. BBM supported growth of the microalgae much better. The physicochemical properties portrayed Majopa and Ogunpa River water as unfit for drinking, while that of Uren River is relatively fit for drinking. It is highly recommended that the microalgae reported therein be further characterised for various possible economic benefits.
The Effects of Aerobic Endurance Training and Circuit Training Program on Cardiovascular Endurance among Junior Archers

The purpose of this study was to examine the effects of aerobic endurance training and circuit training program on cardiovascular endurance among junior archers. The study involved 21 junior archers (age= 15.0 ± 1.7 years) both from recurve and compound division of Terangganu and Penang State’s team. The sample study was randomly divided into three groups: Aerobic Endurance Training group (AET; n=7), Circuit Training group (CT, n=7) and Control group (CON, n=7). Baselines data on height, body mass (kg), body mass index (BMI), percentage body fat (%), cardiovascular endurance (20m Endurance Shuttle Run Test) and VO2 max (maximal oxygen uptake) were collected. The aerobic endurance training program is jogging for 2km in week 1-4, 3km in week 5-8, and 4km in week 9-12. Meanwhile, for the circuit training program included one circuit of ten stations of 30/60 seconds of work/rest interval with two cycles in week 1-4, 40/60 seconds of work/rest interval with three cycles in week 5-8, and 50/90 seconds of work/rest interval with four cycles in week 9-12. Both training program were performed two times per week during evening after archery training routine. Data were analyzed using mixed factorial analysis of variance (ANOVA). Statistical significance level was set at 0.05. The result show that after 12 weeks of a training program, cardiovascular endurance and VO2 max increased significantly in the CT Group (p < 0.05), while for the AET Group revealed significant interactions after week 1-4 and week 9-12 of training and significant increase was not observed in the CON Group (p < 0.05). The results of this study suggest that the circuit training linearly improved cardiovascular endurance and VO2 max of the study subjects throughout the European Journal of Molecular & Clinical Medicine ISSN 2515-8260 Volume 07, Issue 02, 2020 4059 intervention. This training program may be used as a guideline for selecting a set of exercise in their training routine to improve cardiovascular fitness among archers.
Risk Factors of Hepatocellular Carcinoma: An Updated Overview

With around 500000 new cases each year, HCC is the fifth most common cancer in the world and the third leading cause of cancer-related death. Nearly three-quarters of all hepatic malignancies are HCC. It has been listed as the fourth most frequent cancer in Africa. In Egypt, the incidence of HCC has grown. According to Egyptian studies, the rate of HCC cases has increased from 4% in 1993 to 7.3 percent in 2003. It is one of the most lethal cancers, with recurrence and metastasis after surgical resection. HCC has a significant death rate, particularly in people detected late in the disease's progression due to the lack of symptoms in the early stages. Because of the lack of screening techniques in impoverished nations, this problem is particularly pronounced Hepatitis B and C infections are the most common causes of HCC, but persistent alcohol consumption, metabolic disorders (such as diabetes and obesity), and aging can all play a role in the development and progression of HCC. Hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infections cause about 80% of HCC cases, especially in the setting of pre-existing cirrhosis or severe fibrosis. People with HCV infection develop chronic hepatitis in 60–80% of cases, and 10–20% of those patients develop cirrhosis within 20–30 years. HCC can occur in 1–5% of patients with cirrhosis of the liver. Despite the fact that infection rates are reducing in industrialized countries, cirrhosis and hepatocellular carcinoma (HCC) mortality remains a big concern in Egypt. Patients infected with HCV have a 17-fold greater chance of developing HCC. Egypt has the world's highest HCV prevalence rate, with 14.7 percent of the population infected.
Value of T2 weighted Image and Diffusion-weighted MR Imaging in Characterization of Breast Masses

Diffusion-weighted (DW) MRI is a rapid technique that measures the mobility of water molecules within tissue, reflecting the cellular microenvironment. DW MRI produces images that are sensitive to water displacement at the diffusion scale and quantifies such diffusion according to an index that reflects the apparent freedom of diffusion, called the apparent diffusion coefficient (ADC). It has been reported to produce higher detection rates than conventional methods. [3]
IT’S NOT WHAT IT SEEMS! THE MEDIATING ROLE OF SELF-EFFICACY IN THE RELATIONSHIP BETWEEN TRAIT-ANXIETY AND INTOLERANCE OF UNCERTAINTY DURING COVID-19 PANDEMIC

The current research is aimed at studying the relationship between trait anxiety and intolerance of uncertainty, with its both facets: the inhibitory and the prospective anxiety and to establish whether or not the general self-efficacy plays a mediating role between the trait-anxiety and intolerance of uncertainty. Results show that a partial mediation takes part when general self-efficacy mediates the relationship between the intolerance of uncertainty, inhibitory anxiety, but a limited mediation when general selfefficacy interferes in the relationship between the trait-anxiety and intolerance of uncertainty, perspective anxiety. The main benefit of this paper is to demystify the impact of self-efficacy especially in unexpected, unknown situations, such as the COVID-19 pandemic.
ZERO-DIVISOR GRAPHS OF 2× 2 UPPER TRIANGULAR MATRIX RINGS OVER Zn

Istvan Beck introduced the zero-divisor graph in 1988. We explore the directed and undirected zero-divisor graphs of the rings of 2× 2 upper triangular matrices mod n, denoted by Γ(T2(n)) and Γ̃(T2(n)), respectively. For prime p, we completely characterize the graph Γ(T2(p)) by partitioning T2(p), and prove several key properties of the graphs using this approach. We establish additional properties of Γ(T2(n)) for arbitrary n. We prove that Γ(T2(n)) is Hamiltonian if and only if n is prime, and we give explicit formulas for the edge connectivity and clique number of Γ(T2(n)) in terms of the prime factorization of n.
