Hebrew
Hebrew (; ; ) is a Northwest Semitic language of the Afroasiatic language family. Historically, it is one of the spoken languages of the Israelites and their longest-surviving descendants, the Jews and Samaritans. It was largely preserved throughout history as the main liturgical language of Judaism (since the Second Temple period) and Samaritanism. Hebrew is the only Canaanite language still spoken today, and serves as the only truly successful example of a dead language that has been revived. It is also one of only two Northwest Semitic languages still in use, with the other being Aramaic. The earliest examples of written Paleo-Hebrew date back to the 10th century BCE. Nearly all of the Hebrew Bible is written in Biblical Hebrew, with much of its present form in the dialect that scholars believe flourished around the 6th century BCE, during the time of the Babylonian captivity. For this reason, Hebrew has been referred to by Jews as '' Lashon Hakodesh'' (, ) since an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Full Professor
Professor (commonly abbreviated as Prof.) is an academic rank at universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital letter nearly always refers to a full professo ...

Academic Staff Of The University Of Haifa
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Education In Israel
The education system in Israel consists of three tiers: primary education (grades 1–6, approximately ages 6–12), middle school (grades 7–9, approximately ages 12–15) and high school (grades 10–12, approximately ages 15–19). Compulsory education takes place from kindergarten through 10th grade. The school year begins on September 1 (September 2 if September 1 is on Saturday), ending for elementary school pupils on June 30 (June 29 if June 30 is on Saturday), and for middle school and high school pupils on June 20 (June 19 if June 20 is on Saturday). Haredi Yeshivas follow an independent schedule, starting on 1 Elul. Israeli culture views higher education as the key to higher mobility and socioeconomic status in Israeli society. For millennia medieval European antisemitism often forbade the Jews from owning land and farming, which limited their career choices for making a decent living. This forced many Jews to place a much higher premium on education allowing them to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academic Freedom
Academic freedom is a moral and legal concept expressing the conviction that the freedom of inquiry by faculty members is essential to the mission of the academy as well as the principles of academia, and that scholars should have freedom to teach or communicate ideas or facts (including those that are inconvenient to external political groups or to authorities) without fear of repression, job loss, or imprisonment. While the core of academic freedom covers scholars acting in an academic capacity - as teachers or researchers expressing strictly scholarly viewpoints -, an expansive interpretation extends these occupational safeguards to scholars' speech on matters outside their professional expertise. Especially within the anglo-saxon discussion it is most commonly defined as a type of freedom of speech, while the current scientific discourse in the Americas and Continental Europe more often define it as a human right with freedom of speech just being one aspect among many within t ...

Oxford University Press
Oxford University Press (OUP) is the university press of the University of Oxford. It is the largest university press in the world, and its printing history dates back to the 1480s. Having been officially granted the legal right to print books by decree in 1586, it is the second oldest university press after Cambridge University Press. It is a department of the University of Oxford and is governed by a group of 15 academics known as the Delegates of the Press, who are appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho. For the last 500 years, OUP has primarily focused on the publication of pedagogical texts and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superiorization
Superiorization is an iterative method for constrained optimization. It is used for improving the efficacy of an iterative method whose convergence is resilient to certain kinds of perturbations. Such perturbations are designed to "force" the perturbed algorithm to produce more useful results for the intended application than the ones that are produced by the original iterative algorithm. The perturbed algorithm is called the superiorized version of the original unperturbed algorithm. If the original algorithm is computationally efficient and useful in terms of the target application and if the perturbations are inexpensive to calculate, the method may be used to steer iterates without additional computation cost. Areas of application The superiorization methodology is very general and has been used successfully in many important practical applications, such as iterative reconstruction of images from their projections,G.T.

IMRT
Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a therapy using ionizing radiation, generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer). Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers. The subspecialty of oncology concerned with radiotherapy is called radiation oncology. A physician who practices in this subspecialty is a radiation oncologist. Radiation therapy is commonly applied to the cancerous tumor because of its ability to control cell growth. Ionizing radiation works by damaging the DNA of cancerous tissue l ...

Israelis
Israelis ( he, יִשְׂרָאֵלִים, translit=Yīśrāʾēlīm; ar, الإسرائيليين, translit=al-ʾIsrāʾīliyyin) are the citizens and nationals of the State of Israel. The country's populace is composed primarily of Jews and Arabs, who respectively account for 75 percent and 20 percent of the national figure; followed by other ethnic and religious minorities, who account for 5 percent. Early Israeli culture was largely defined by communities of the Jewish diaspora who had made '' aliyah'' to British Palestine from Europe, Western Asia, and North Africa in the late-19th and early-20th centuries. Later Jewish immigration from Ethiopia, the states of the former Soviet Union, and the Americas introduced new cultural elements to Israeli society and have had a profound impact on modern Israeli culture. Since Israel's independence in 1948, Israelis and people of Israeli descent have a considerable diaspora, which largely overlaps with the Jewish diaspora b ...
