The document discusses the Advanced Encryption Standard (AES), which was selected by the US National Institute of Standards and Technology (NIST) in 2000 to replace the Data Encryption Standard (DES). AES uses 128-bit blocks and supports key sizes of 128, 192, and 256 bits. It is based on the Rijndael cipher designed by Vincent Rijmen and Joan Daemen. AES operates on a 4x4 column-major order matrix of bytes and uses substitutions, transpositions, and mixing operations along with adding a round key to transform the input, with decryption being the inverse process using the round keys in reverse order.

The document outlines different types of love, including romantic love, sexual love, pragmatic love, platonic love, companionship love, altruistic love, manic love, hostile love, and self-love. It concludes by stating that an ideal marriage incorporates experiencing all types of love everyday, and while not married one can still experience most types of love with different people.
The document discusses different types of love from a psychological perspective. It defines love as an active process of giving, rather than a passive feeling, and identifies key elements such as care, responsibility, respect and knowledge. It examines different forms of love including brotherly love, motherly love and erotic love. Erotic love in particular is described as craving fusion with one other person, but can be deceptive if not grounded in broader qualities like care, responsibility and respect. Sternberg's triangular theory of love is also briefly referenced.
This poem discusses the importance of listening to understand others' problems and needs, praising even small accomplishments, tolerating chatter and amplifying laughter. It also stresses overlooking faults, using a kind voice, and making an effort to find out what really matters to people or what they seek.
The document discusses the author's relationship with his girlfriend. It describes their ups and downs over the course of their relationship, including feeling deeply in love with her from the beginning, going through difficult times that led to a breakup due to mistakes he made, being heartbroken during their time apart, and then being reunited after praying to God and her giving him a second chance. The author expresses his ongoing love for his girlfriend and gratitude for their continued relationship.
1) Romantic love involves intense feelings driven by hormones and neurotransmitters that encourage reproduction. Dopamine released during attraction causes euphoria similar to cocaine, while oxytocin and vasopressin released during sex and orgasm promote attachment between partners.
2) Scientists have identified three stages of love: lust driven by testosterone and estrogen, attraction involving adrenaline, dopamine and serotonin, and attachment related to oxytocin and vasopressin which bond parents to children and long-term partners.
3) Studies show decisions about attraction can be made within 90 seconds based mostly on body language, tone of voice rather than words, and new love can cause obsessive thinking from low serotonin like OCD patients.
What actually is love from a scientific point of view? In the field of neurochemistry and neuropsychiatry love is explained by 8 different chemicals your body produces.
This document discusses love, friendship, and human relations. It provides several quotes about the topics, such as "LOVE is a short word but it contains everything" and "Friendship is the hardest thing in the world to explain. It’s not something you learn in school." The document emphasizes that love is the principle of existence and friendship is one of life's blessings, as friends overlook failures and tolerate success. It concludes by thanking the reader and stating that the document will be continued.
The document discusses different types of love portrayed in literature:
1) Sensual love focuses on physical attraction and intimacy between lovers.
2) Tragic love and impossible love refer to love that cannot be achieved or realized due to external circumstances.
3) Idealized love involves emotional and sexual desire mixed with seeing the loved one as perfected or superior.
4) Love tyrant refers to love that deprives one's freedom, while courtly love depicts love of a noblewoman that may or may not be reciprocated or consummated.
Love should be the goal in one's life and actions. True love means fully accepting others without expectations, and demonstrating care for their spiritual growth through selfless service. When one opens their heart to love all people and things, even in their flaws, they will perceive the divine mystery in the world and comprehend it through an all-embracing love.
This document provides an overview of the biology of love. It discusses three stages of love: lust, romantic love, and attachment. It summarizes several studies that examine the roles of dopamine and serotonin in romantic love and obsession. One study found dopamine is involved in goal-seeking and reward pathways when viewing a partner's photo. Another study found lower serotonin levels in those newly in love and with OCD. Oxytocin is discussed in several studies as influencing bonding, relationships, and communication between partners.
Invited talk at the European Research Council-Brussels (Scientific Seminar, 12 April 2013): "Love for Science or 'academic prostitution'". In this talk I present a personal revision (sometimes my own vision) of some issues that I consider key for doing Science. It was focused on the expected audience, mainly Scientific Officers with background in different fields of science and scholarship, but also Agency staff.
Abstract: In a recent Special issue of Nature concerning Science Metrics it was claimed that " Research reverts to a kind of 'academic prostitution' in which work is done to please editors and referees rather than to further knowledge."If this is true, funding agencies should try to avoid falling into the trap of their own system. By perpetuating this 'prostitution' they risk not funding the best research but funding the best sold research.
Given the current epoch of economical crisis, where in a quest for funds researchers are forced into competitive game of pandering to panelists, its seems a good time for deep reflection about the entire scientific system.
With this talk I aim to provoke extra critical thinking among the committees who select evaluators, and among the evaluators, who in turn require critical thinking to the candidates when selecting excellent science.
I will present some initiatives (e.g. new tracers of impact for the Web era- 'altmetrics'), and on-going projects (e.g. how to move from publishing advertising to publishing knowledge), that might enable us to favor Science over marketing.
The document discusses different perspectives on defining the concept of love. It examines preconceptions that love is about romance, possession, or sex. It also references Erich Fromm's book The Art of Loving which emphasizes the state of "falling in love" rather than a permanent condition. The document then explores original experiences of love, including loneliness overcome through loving encounters, reciprocity between partners, creativity within the relationship, union and sacrificial gift of self, the historical nature of love, equality between partners, and the total, eternal and sacred nature of authentic love.
The document discusses the different types and definitions of love from various perspectives. It explores love from biological, psychological, evolutionary, and religious viewpoints. Biologically, love is seen as a drive to facilitate reproduction through stages of lust, attraction, and attachment. Psychologically, love involves intimacy, commitment, and passion. Evolutionarily, love helps promote parental support of children and prevent disease. In Christianity, the greatest commandment is to love God and others unconditionally.
The document discusses various perspectives on the concept of love. It defines love as an action rather than a feeling, involving commitment, attention, and risk. Love is choosing to nurture another person's growth through both good and bad times. True love is demonstrated through caring actions over time rather than fleeting feelings alone.
This document outlines seven stages of relationships: 1) Romance, 2) Power Struggle, 3) Disillusionment, 4) Awareness, 5) Stability, 6) Commitment, and 7) Teamwork. It describes the needs satisfied and characteristics at each stage, noting that couples may be at different stages which can cause issues. The power struggle and disillusionment stages are when counseling is most common and divorce may occur. Reaching the commitment stage requires awareness, choice, and readiness from both partners.

This document discusses the relationship between love, spirituality, and science. It notes that while science seeks material explanations for phenomena, love and spirituality are not fully explained by physical or chemical processes. The document advocates that science and spirituality can be complementary, with science explaining how things work and spirituality providing purpose and meaning. It encourages readers to be open to both rational inquiry and spiritual understanding.
The document summarizes C.S. Lewis's analysis of the four main types of love - affection, friendship, eros, and charity - as discussed in his book The Four Loves. Lewis states that these four loves are based on the four Greek words for love. He argues that just as Lucifer fell from grace through pride, so too can love become corrupt if it presumes itself to be something it's not. The document then provides further details on Lewis's perspective for each type of love - affection being natural familial love, friendship being a freely chosen bond, eros being romantic love, and charity being unconditional love that must subordinate the other loves.
This document appears to be promoting election services for clubs, credit unions and associations in Australia. It mentions True Love Music performed by Bing Crosby and Grace Kelly. The contact email address is also included.
The document describes 8 types of love relationships based on the factors of intimacy, passion, and commitment. The types range from casual relationships with no intimacy, passion, or commitment, to consummate love which involves high levels of all three factors and describes long-term relationships. Companionate love involves intimacy and commitment but not passion, often seen in long-term marriages where the initial passion has faded.
This document discusses neurons, neurotransmitters, and their impact on human behavior. It defines key terms like neuron, dendrite, axon, synapse, and neurotransmitter. It explains how neurons communicate via neurotransmitters released at the synapse between neurons. Serotonin imbalance is linked to depression, and SSRIs work by blocking serotonin reuptake. The document also summarizes a study that found acetylcholine plays a role in memory formation by manipulating its levels in rats. Dopamine is associated with reward and motivation rather than directly creating pleasure.
