Cryptography is concerned with the conceptualization, definition, and construction of computing systems that address security concerns. The design of cryptographic systems must be based on firm foundations. This book presents a rigorous and systematic treatment of the foundational issues: defining cryptographic tasks and solving new cryptographic problems using existing tools. It focuses on the basic mathematical tools: computational difficulty (one-way functions), pseudorandomness, and zero-knowledge proofs.

The goal of this book is to give you the skills and knowledge necessary to succeed in calculus. Much of the difficulty calculus students face is with algebra. They have to solve equations, find equations of lines, study graphs, solve word problems, and rewrite expressions—all of these require a solid background in algebra. You will get experience with all this and more in this book. Not only will you learn about the basic functions in this book, you also will strengthen your algebra skills because all of the examples and most of the solutions are given with a lot of detail.

SMEs play an important role in economic development in every country. However, the growths of SMEs are hampered because of their difficulties in accessing external capital. In this context, the application of the concept of sustainable supply chain in the operation strategy of SMEs seems to be a very important function. This supply chain also covers all three aspects of sustainable development: business, environmental, and social. This study aims at investigating the experience of supply chain management in evaluating the worthiness of SMEs to improve operation.

Children with autism spectrum disorder “are people under the age of 16 with a distinct symptom of neurodevelopmental disorder caused by impairments in social interaction and communication, express shaped behavior and have one of restricted functions in their lives”. Based on the list of children’s developmental behavioral disorders applied at the National Children’s Hospital, the article focuses on 3 main groups of difficulties of children with autism spectrum disorder, including emotion, cognitiveness - behavior and social communication.

Ostomy has become a common therapy for treating gastrointestinal diseases such as colorectal cancer. Patients with ostomy experience many problems including appearance change, uncontrolled discharge and odour, sexual dysfunction, decreased social functioning, and difficulties taking care of themselves. This study aimed to survey the level of psychological adjustment and to determine factors associated with the level of psychological adjustment in patients with ostomies.

Ankyloglossia is commonly reported as one of the major causes of breastfeeding difficulty. There is a lack of research on infant growth and latching performance with clinical measures. In the cases reported in this paper, the infants overcame the initial difficulties in breastfeeding and maintained their normal growth course in the first 6 months of life.

The article proposes a method for constructing public-key block cipher schemes based on the difficulty of the discrete logarithm problem on elliptic curves. The schemas are construc according to the proposed method and can simultaneously perform security functions and authenticate the origin and integrity of the encrypted message.

Life expectancy has increased over the last century and a growing number of people is reaching age 90 years and over. However, data on nonagenarians’ health trends are scarce due to difficulties in investigating this specific population. This study aims to identify risk factors for one-year mortality in nonagenarians using data collected within the “Mugello Study”

Dual-task gait performance declines as humans age, leading to increased fall risk among older adults. It is unclear whether different secondary cognitive tasks mediate age-related decline in dual-task gait. This study aimed to examine how type and difficulty level of the secondary cognitive tasks differentially affect dual-task gait in older adults.

Nanoclusters have been emerging as potential building blocks for advanced nanostructured materials with desired catalytic, magnetic, and electronic properties. However, determining the structure of doped atomic clusters encounters many difficulties. A powerful approach to assign the ground state geometries of atomic clusters has been the comparison the recorded vibrational infrared spectra with the corresponding computed ones.

Silsesquioxane-based transition-metal complexes have come to the forefront due to the ability of silsesquioxane to control nanostructures and properties. However, some difficulties in complete complexation and purification limit the widespread use of transition-metal-based supramolecular coordination complexes comprising silsesquioxane. Herein, 2 different approaches have been proposed for the synthesis of metallo-supramolecular materials on the basis of ruthenium(II)-terpyridine functional double-layer silsesquioxane (DDSQ) (Tpy/Ru-DDSQ) (Routes 1 and 2).

In the university environment, communication and interaction between students and teachers are essential. However, students of Hanoi University face many difficulties in finding contact information with their teachers as well as other departments in the university. With the development of the technology age 4.0 along with the existing problems of the university, the HANUCommunication website was created to connect HANU students and faculty together using Javascript, Mongodb and Socketio technologies.

Discovered about two decades ago, piRNAs are a large and versatile type of sncRNA and that remain insufficiently identified and analyzed, through next-generation sequencing (NGS), to evaluate their processing, functions, and biogenesis in different cell types and during development. piRNAs’ distinction from other sncRNAs has led to controversial results and interpretation difficulties when using existing databases because of the heterogeneity of the criteria used in making the distinction.

Genome wide association studies (GWAS) have helped identify large numbers of genetic loci that significantly associate with increased risk of developing diseases. However, translating genetic knowledge into understanding of the molecular mechanisms underpinning disease (i.e. disease-specific impacted biological processes) has to date proved to be a major challenge. This is primarily due to difficulties in confidently defining candidate genes at GWAS-risk loci.

Chrysanthemum indicum L., an important ancestral species of the flowering plant chrysanthemum, can be used as medicine and for functional food development. Due to the lack of hereditary information for this species and the difficulty of germplasm identification, we herein provide new genetic insight from the perspective of intraspecific transcriptome comparison and present single sequence repeat (SSR) molecular marker recognition technology.
