Brief Answer to the Big Questions میں تخلیق کائنات کے ملحدانہ دلائل کا تنقیدی جائزہ

Atheism is a major topic of discussion in modern time. Critical study of Contemporary atheist literature is a bona-fide task for the emerging researchers for the decontamination of Muslim youth. On the basis of Rationality, Empiricism and critical thinking, brains are draining toward the realm of non-religions. Every person born on the nature of Islam but onward adopt the prevailing doctrines. In the past century an overwhelming critique has been put in academic field by the new atheists in favouring atheism in masquerading by science. Science has nothing to do with supernatural or metaphysical phenomena. Atheism is being attributed to modernity. Considering overwhelming scientific attacks by contemporary atheist, it is the need of the hour to tackle account seriously and use Islamic doctrine to cope the penetrating insurgency of atheist through in Islamic world. Stephen hawking (late) is a famous theoretical physicist and has imparted a valuable influential thoughts regarding origin of time, origin of universe and other hot cosmological and physical issues. Brief answers to the big questions are his last compilation. He argues that for interpretation of origin of Universe nothing has to be with personal God. Instead of attributing God, he attributes the laws of nature for the origin of universe. He argues that it was “time” that causes the universe to begin. He mixed up mythical accounts with the creation accounts as described by the revelation of different religions. In first chapter, he focused on the question: Is there a God? He deliberately asked the question and mentioned that science has the capacity to answer that very question. He argues that before creation of universe God does not have “time” to initiate or trigger and creation process and hence God does not exit. Hawking arguments regarding origin of Universe and existence of God has been critically analysed.

Four Years of Earthquake Early Warning in Southern Iberia: 2016–2019

The performance of an earthquake early warning system (EEWS) for southern Iberia during the period of 2016–2019 is analyzed. The software PRESTo (PRobabilistic and Evolutionary early warning SysTem; the University of Naples Federico II, Italy) operating at the Universidad Complutense de Madrid has detected 728 events (2 < Mw < 6.3), with 680 earthquakes occurring in southern Iberia. Differences between the EEWS origin time and epicenter and those of the Instituto Geográfico Nacional (IGN) catalog are less than 2 s and 20 km, respectively, for 70% of the detected earthquakes. The main differences correspond to the EEWS magnitude that is underestimated for earthquakes that occurred at the west of the Gibraltar Strait (Mw differences larger than 0.3 for 70%). To solve this problem, several relationships have been tested, and a modification to those that currently use PRESTo is proposed. Other improvements, such as to densify the network or to use 3D Earth models, are proposed to decrease the time needed to issue the alert and avoid the false alerts (19 events over a total of 728 events). The EEWS has estimated the depth for 680 events and compared to those from the IGN (491 events). The performance of PRESTo during the 2020–2021 Granada swarm is analyzed. The hypocentral locations for the three largest earthquakes are close to those from the IGN (differences from 1 to 7 km for the epicenter and 0 s for the time origin), although there are some differences in their magnitude estimations that varies from 0.2 to 0.5. The PRESTo first times are 17, 25, and 41 s after the origin time. This study shows that the actual PRESTo EEWS configured for the southern Iberia may generate effective warnings despite the low seismicity rate in this region. To decrease the warning time, the geometry and density of the seismic network must be improved together with the use of 3D Earth models and on-site system approaches.

Group Formation in Shared Spaces

In shared spaces, grouped pedestrians can gain dominance and thus get the right of way from vehicles more easily; grouping can make traffic planning less complicated, e.g. it reduces the number of agents that need to be considered while traffic planning. However, grouping is not well investigated in shared spaces given the dynamic environment and interactions in mixed traffic. In this paper, we apply a dynamic facility location algorithm based on appearance time, origin, and destination of road users before crossing a junction to explore an appropriate grouping strategy in shared spaces, in order to improve the safety and efficiency of traffic.

Results of 40Ar/39Ar dating of subvolcanic body in the vent tunnelKukurtly volcano

Эльбрус изучается с 1852 г., однако вопросы о времени его образования и временных этапах эволюции до сих пор остаются дискуссионными. По мере развития новых методов датирования геологических событий исследователями Эльбру- са применялись все более современные методы и методики. Так, на самых ранних этапах исследований время образования вулкана приблизительно оценивалось только по геологическим данным, затем стал очень широко применяться геолого-гео- морфологический метод относительной геохронологии, а с конца прошлого столетия – калий-аргоновый (K-Ar), аргон-арго- новый (40Ar/39Ar), иониевый (Io/234U) и радиоуглеродный (14C) методы датирования. В полученных вышеуказанными методами датировках (цифрах возрастов) по одному и тому же объекту часто имелись существенные различия. При 40Ar/39Ar датировании биотита из туфов риолитового состава раннего этапа кальдерной стадии было доказано, что при эксплозивных извержениях, приведших к формированию этих туфов и ассоциирующих с ними игнимбритов, был захвачен дезинтегрированный материал древнего гранитно-метаморфического основания Эльбруса, который после аэрального пере- носа стал составной частью туфов и игнимбритов. Следовательно, все изотопные датировки этого пирокластического материала (по биотиту, пироксену, плагиоклазу) не отражают время образования рассматриваемых пород, так как они со- держат мельчайшие обломки древнего гранитно-метаморфического фундамента и слагающего их породообразующего био- тита, что, естественно, искажает изотопный возраст пирокластики в неизвестном масштабе. Устойчивое плато при ступенчатом нагревании пробы № 542 мегакристалла санидина однозначно свидетельствует об от- сутствии избыточного аргона, а полученный аргон-аргоновый возраст (620.3±3.3 тыс. лет) отражает время остывания кри- сталла санидина при температуре закрытия системы ~ 300о С и свидетельствует об отсутствии значительного перерыва во времени между формированием пород раннего и позднего этапов кальдерной стадии. Ключевые слова: вулкан Эльбрус, 40Ar/39Ar датирования, субвулканическое тело дацитового состава, жерло вулкана Кюкюрт- ли, удревнение или омоложение изотопного возраста. Elbrus is under study since 1852 year, however the questions about time of it origin and temporal stage of evolution, up to now are remains as a discussional.So far as development of a new method for dating of geological events, investigators of Elbrus using all more current status of methods and procedures.So, on the very early stages of investigation, time of volcano origin approximately assessed by geological data only, then -geologo-geomorphological method of relative geochronology became in very regular use and from last century - potassium-argon (K-Ar), argon-argonian(40Ar/39Ar), ionic (Io/234U) and radio-carbon(14C) methods of dating. Inobtainedbytheabovementionedmethodsofdating (fi gureofage) oncommon poles object very often there was an fundamental dissimilarities. As a result of 40Ar/39Ar dating of biotite from tuff of the rhyolite composition of early period of calderian stage, it was proved, that during explosive eruption, lead to forming of these tuff and associated ignimbrites, the old disintegrated material of granite-metamorphic basement of Elbrus was encroach and which after aeral transportation became as a constituent part of tuff and ignimbrites. Consequently, all isotope age determination of this pyroclastic material (on biotite, pyroxene, plagioclase) do not take account of time origin of covered rocks, as they contain a very small debris of old granite-metamorphic basement and rock-building biotite, that natural, to distort of isotope age of pyroclastics in unknown scale. The tolerant plateau at scalariform heating sample № 542 - megacrystal of sanidine is uniquely testifi es about absence of excess argon and argon-argon age (620.3±3.3Ka) obtained is accounts time of cooling down ofsanidinemegacrystal at the temperature of clousing of the system - 3000 C and testifi es about absence of signifi cant interruption in time between rock forming of early and late periods of calderian stage

Correlating USA COVID-19 cases at epidemic onset days to domestic flights passenger inflows by state

In the USA, COVID-19 first infection cases were imported by external travelers. At the epidemic onset days, we assume that the disease partially spreads due to domestic passengers air transportation in its densely connected airport network. Taking into account all USA states, we arranged COVID-19 infected cases data in a convenient common time origin timeline as if the beginning of the epidemic would have occurred simultaneously in every state. Looking for a trend between cases and air passengers, we obtained with this timeline very good statistical Pearson and Spearman correlations between accumulated infected cases by state and a positive power of the product [Formula: see text], where [Formula: see text] is the domestic flight passengers (travelers) inflow by state before the epidemic and [Formula: see text] is its population. We also found a good correlation between percentages of urban area by state and their COVID-19 daily new cases growth rates at onset days.

COVID-19 cases in countries and territories at onset days as function of external tourism inflows

In every country except China, COVID-19 first infection cases were imported by travelers, which are either people coming back to their own country or visiting foreigners (international or external tourists). In a global and regional phenomenological analysis of COVID-19 spread, we assume that tourism inflow is a trigger mechanism of worldwide dissemination at the pandemic onset days. Taking into account all countries, a convenient common-time origin timeline was employed as if the beginning of the epidemic would have occurred simultaneously in every country. We obtained very good statistical Pearson and Spearman correlations between accumulated infected cases by country and a positive power of the product [Formula: see text], where [Formula: see text] is the tourism inflow before the pandemic and [Formula: see text] is the country population.
