Dietary fiber and prebiotics consistently modulate microbiota composition and function and hence may constitute a powerful tool in microbiota-gut-brain axis research. However, this is largely ignored in Hooks et al.’s analysis, which highlights the limitations of probiotics in establishing microbiome-mediated effects on neurobehavioral functioning and neglects discussing the potential of prebiotics in warranting the microbiota's role in such effects.

The present article deals with an observer design for nonlinear vehicle lateral dynamics. The contributions of the article concern the nonconsideration of any force model and the consideration that the longitudinal velocity is time varying, which is more realistic than the assumption that it is constant. The vehicle model is then represented by an exact Takagi–Sugeno model via the sector nonlinearity transformation. A proportional multiple integral observer based on the TS model is designed to estimate simultaneously the state vector and (...) the unknown input. The convergence conditions of the estimation error are expressed under LMI formulation using the Lyapunov theory, which guaranties a bounded error. Simulations are carried out for comparison between the conventional PI observer, the enhanced PI observer, and the PMI observer. Finally, experimental results are provided to illustrate the performances of the proposed PMI observer. (shrink)

This research aims, first of all, to establish that Abû Hanîfa's (d. 150/767) positive view on the issue of performing wudû’ with nabîdh of date is correct, and then to reveal Abû Hanîfa's dalîls on this subject. The issue of wudû’ with nabîdh of date is controversial among early Hanafî jurists, and the jurist who expressed a positive opinion on this issue is Abû Hanîfa, the founding imam of the madhhab. The opinion that wudû’ can be performed with nabîdh of (...) date is the strong opinion of Abû Hanîfa mentioned in zâhir al-riwâya. The riwâya reported by Nûh bin Abi Maryam (d. 173/789) stating that Abû Hanîfa reneged on this view is not strong enough to oppose the view in zâhir al-riwâya. For this reason, it is not a correct approach to ignore the view in zâhir al-riwâya based on this riwâya. As a matter of fact, Abû Hanîfa's view of zâhir al-riwâya is conveyed in many of the classical Hanafî texts such as Mukhtasar al-Karkhi and Mukhtasar al-Tahâwî. Although the majority of Hanafî jurists preferred the view of Abû Yûsuf (d. 182/798), a significant group of Hanafî jurists such as Jassâs (d. 370/981), Kâshânî (d. 587/1191) and ‘Aynî (d. 855/1451) He supports Abû Hanîfa's view. Therefore, there are two views on the issue in Hanafî fıqh. In the literature, the dalîls of Abû Hanîfa's view is not available as a whole in a single source, but is scattered in many Hanafî fiqh sources. The Hanafî jurist Jassâs is the one who deals with the mentioned dalîls in the most comprehensive way in his many works. For this reason, the subject was examined by focusing on Jassâs's dalîls. Jassâs' istidlâls regarding the issue of wudû’ with nabîdh of date also mean defending Abû Hanîfa against other Hanafî jurists such as Abu Yusuf and Imâm Muhammad (d. 189/805). Jassâs' insistent attitude on this issue and his passionate counter-answers prove how much he deserves the title of defense. For the relevant determination, Hanafî fiqh classics are centered. Because the jurists who argue that wudû’ can be made with the nabîdh of date are among the Hanafî jurists. Then, the positive and negative approaches of the jurists about the nabîdh of date are given. Starting from the early Hanafî jurists, the views of the sahâbîs, the tâbi'ûn and many later jurists on the subject are included. The approach of the four madhhabs of fiqh is also examined in this section. Then, the istidlâls of Jassâs, which is the main subject of the research, were emphasized. It is seen that Jassâs' istidlâls have three main pillars: âya, hadîth and idjma. As a âya, the 6th âya of the sûra of Mâida, as a hadîth, the hadîth of ‘Abd Allâh bin Mas'ûd (r.a.) and as a idjma, the the sahâbîs idjma tries to showas references. The most controversial dalîl is undoubtedly the hadiths of Ibn Mas'ud (r.a.). Jassâs opposes those who claim that the hadîth is da‘îf and discusses the hadîth with its detailed tarîks and argues that this hadîth is sahîh. (shrink)

Understanding the nusus and the interpretation of their texts has been at the center of the activities of many schools and ulama in fiqh studies, and as a result, each school of usool has sought to find a method suitable for their own understanding in order to understand and interpret the nusus in a sahih way. For this purpose, fiqh schools have developed some unique methods. It can be said that the main differences among the hukms that fiqh schools rely (...) on are generally due to these methodological differences. One of the efforts to understand and interpret through the linguistic structures and patterns of the nusus is tawīl. For this reason, it is necessary to know conceptions of tawīl in order to accurately determine the hukm giving methods of fiqh schools. In this context, the thought of Zâhiri Ṭawīl, which is based on the zâhiri meaning of the words in the language and aims to solve the meaning pattern of the nusus within the framework of the rules of the language, is important. To this end, the tawīl understanding of Ibn Hazm (d. 543/1148), one of the leading ulama of Zâhiri thought, has an important position in the determination of their understanding of fiqh and usool. For this purpose, by searching the works of Ibn Hazm, how his understanding of tawīl, which he used as a method, is reflected in his fiqh thought, will be examined through his fiqhi inferences. The Qur’an used their language when addressing the societies. The Qur'an especially, on the one hand, has used the language they use to convey its messages to its interlocutors in a correct and understandable way, on the other hand, it has used a unique style without departing from the natural structure of the language in unseen matters due to the nature of religious language. Therefore, it is necessary to take into account the words of the texts in order to understand and interpret the language used. The word tawīl was used by the ilm circles in the first period to mean the same as the word tafsir and in naming the works written as the Qur’an tafsir, the word tawīl was preferred instead of tafsir. Mâturîdî, the writer of the first dirayah tafsir, which points to the distinction between tafsir and tawīl, defines the word tafsir as 'to express exactly what is the meaning and purpose of the Qur'an, which is the divine word' and states that tafsir can be done only by the the Ṣaḥābah who knows Quran and Sunnah well. According to one of the many theses about the origin of language, it is God given. In other words, language has been taught to man by a supreme power (Allah). Ibn Hazm also defends this view. According to Ibn Hazm, the basic elements / elements of the language were taught by Allah to Adam (a.s), and then people developed this language in proportion to their needs. Therefore, the indications of the words depend on the declarations of God and linguistic experience. As a matter of fact, Allah has attributed new meanings to words such as salat, allegiance, hajj and similar words used for other meanings in the custom of language, and the new meanings attributed to them are accepted as the truth for the meanings of these words. Usûlists who adopted the method of fuqaha in usool, in the methods of istinbat of hukm out of sharii dalils, have generally made the taqseem of the words in terms of the meaning they were given to as âm, khâs, mushtarak and muavval while their taqsseem in terms of the words’ being used or not in the sense they were given was haqiqat, majaz, sarih and kinayah. Compared to other schools, the issue of tawīl has a different meaning according to the Zâhirî usûlists and faqih who base on the zâhiri khitab. Since the zâhir of the nusus is primary and essential, there should be a certain usool, principle and rule to give up the zâhir of the nusus and to switch to another possible meaning. Ibn Hazm states that there are different opinions among the usûlists about whether the imperative form is indicant of hukm. He also says that according to some Hanafi, Malikî and Shafii usûlists, as long as there is no evidence showing that it is wujub, tahrim, nedb, ibahâ and karahah, then the imperative form cannot be views as indicating a hukm.
