Cohomology of acting on linear differential operators on the supercircle $S^{1|1}
We compute the first cohomology spaces
() of the Lie superalgebra with
coefficients in the superspace of linear
differential operators acting on weighted densities on the supercircle
. The structure of these spaces was conjectured in \cite{gmo}. In
fact, we prove here that the situation is a little bit more complicated. (To

Selective perspectives of implementing computer technology in K-12 education in the State of Kuwait
Through this research, the author examined the opinions and attitudes of virtually every segment of the Kuwaiti society (i.e., administrators, teachers, students, parents, and community members) toward the use of computers and technology in K-12 education. A Likert scale questionnaire was the primary vehicle for data collection. This questionnaire was designed to find out value judgments for issues such as implementing computer technology as an independent subject in K-12 schools versus integrating computer technology in all other subjects. A stratified random sample was secured from all five Kuwaiti govemorates (i.e., regions) from 70 schools. The overall number of participants who received the study\u27s survey was 1,190. Of the questionnaires distributed, 1, 165 were returned, for a return rate of 97.89 percent. Both descriptive statistics procedures (e.g., frequency, mean, and standard deviation) and inferential statistics procedures ( e.g., factor analysis, analysis of variance (ANOVA), Tukey\u27s HSD multiple comparisons, and t-test) were conducted
Wife battery in Islam : socio-legal interpretations in Islamic societies
There are more than 1.2 billion Muslims living in more than 184
countries and speaking more than 200 languages and dialects.9 Thus
discussing Islam as an ideology that has a singular interpretation is
impossible and to many social scientists such a discussion represents a
simplified view of the intertwined societal forces and structures. Despite
the existing diversity among Muslims, most agree that the major sources
of Islam are: the Holy Qur’an, the Prophet’s sayings and traditions
(hadith and sunnah), and shari’a (jurists’ legal derivations and
decisions). The sources of Islam are treated hierarchically; jurists go first
to the Qur’an, then to the exegetical works related to the hadith and
sunnah, and finally to the shari’a (juridical corpus). This chapter aims to
look at the unity of the sources as the basis of understanding the issue of

Saudis’ attitude toward principles of modernity: Social progress, individualism, and democracy
This study investigated attitudes of Saudi youth towards modernity and its principles, which are social progress, individualism, and democracy. Methodologically, the study used mixed methods by applying two scientific tools: semi-structured interviews and a survey. Study questions, both close-ended and open-ended, are programmed using REDCap. Data was gathered virtually via Zoom meetings. Twenty-one Saudi youth (10 males and 11 females) aged between 18 and 30 years old participated. They were recruited via social media platforms. Descriptive statistics were conducted to analyze survey data, and an inductive approach was used to analyze the semistructures interviews. The results show that the Saudi youth have an acute awareness and cautious attitudes regarding their own social, cultural, and political circumstances in dealing with modernity and its fundamental principles. However, distrust emerged as an issue in the story of Saudi modernity due to the perception that it is a government-led project and not an internal, dynamic process
Distributed Beamforming with Wirelessly Powered Relay Nodes
This paper studies a system where a set of relay nodes harvest energy
from the signal received from a source to later utilize it when forwarding the
source's data to a destination node via distributed beamforming. To this end,
we derive (approximate) analytical expressions for the mean SNR at destination
node when relays employ: i) time-switching based energy harvesting policy, ii)
power-splitting based energy harvesting policy. The obtained results facilitate
the study of the interplay between the energy harvesting parameters and the
synchronization error, and their combined impact on mean SNR. Simulation
results indicate that i) the derived approximate expressions are very accurate
even for small (e.g., ), ii) time-switching policy by the relays
outperforms power-splitting policy by at least dB.Comment: 4 pages, 3 figures, accepted for presentation at IEEE VTC 2017 Spring

Synthesis and Characterization of New Derivatives of Thiazole with Liquid Crystalline properties
A new two series of liquid crystalline Schiff bases containing thiazole moiety with different length of alkoxy spacer were synthesized, and the relation between the spacer length and the liquid crystalline behavior was investigated. The molecular structures of these compounds were performed by elemental analysis and FTIR, 1HNMR spectroscopy. The liquid crystalline properties were examined by hot stage optical polarizing microscopy (OPM) and differential scanning calorimetry (DSC). All compouns of the two series display liquid crystalline nematic mesophase. The liquid crystalline behaviour has been analyzed in terms of structural property relationship.
