Koliko znanost treba ili može utjecati na teološke formulacije? Ashʿarījev pogled na teologiju prirode

There have been many developments in the field of science and religion over the past few decades. One such development is referred to as ‘theology of nature’ (ToN), which is the activity of building or revising theological frameworks in light of contemporary scientific developments, e.g., evolution, chaos theory, and quantum mechanics. Ian Barbour, John Polkinghorne, and Arthur Peacocke, all of whom are Christian thinkers, are the most well-known advocates of this kind of thinking. However, this discourse has not been examined from an Islamic perspective. Given this gap, in this article, we view this strand of thinking from the Ashʿarī school of thought that is part of the Sunnī Islamic kalām tradition. We first review how ToN manifests in the works of the thinkers mentioned earlier. Following this, we highlight the essential principles in Ashʿarism relevant to God, His interaction with the created world, and science. These are then compared with the ideas of the said thinkers. Two conclusions are reached. First, we demonstrate that atomism, which is generally understood as a long-held position in the Ashʿarī tradition, should not be held as a theological position but rather a philosophical or a scientific one. Second, an important distinction is made between science-informed theology (SIT) and contingency-informed theology (CIT). For Ashʿarīs, a CIT is sufficient for understanding God, but they would find the SIT displayed in ToN problematic. The motivation and methodology of localising or modifying God’s nature or attributes to fit the science of the day would be seen as theologically very costly and a form of scientism.U posljednjih nekoliko desetljeća svjedočimo velikom razvoju istraživanja na području znanosti i religije. Jedan takav razvoj naziva se \u27teologija prirode\u27 (ToN), što uključuje aktivnost izgradnje ili revizije teoloških okvira u svjetlu suvremenih znanstvenih razvoja, npr. evolucije, teorije kaosa i kvantne mehanike. Ian Barbour, John Polkinghorne i Arthur Peacocke, kršćanski mislioci, najpoznatiji su zagovornici ove vrste razmišljanja. Međutim, ovaj diskurs nije ispitan iz islamske perspektive. S obzirom na ovaj jaz, u članku razmatramo ovaj način razmišljanja iz perspektive Ashʿarī škole mišljenja koja je dio sunitske islamske kalām tradicije. Prvo ćemo razmotriti kako se ToN manifestira u djelima ranije spomenutih mislilaca. Nakon toga ističemo bitna načela ašʿarizma koja su relevantna za Boga, Njegovu interakciju sa stvorenim svijetom i znanost. One se potom uspoređuju s idejama navedenih mislilaca. Dolazimo do dva zaključka. Prvo, pokazujemo da se atomizam, koji se općenito shvaća općeprihvaćeno stajalište u Ashʿarī tradiciji, ne bi trebao smatrati teološkimgledištem, već prije filozofskim ili znanstvenim. Drugo, napravljena je važna razlika između znanstveno informirane teologije (SIT) i kontingentno informirane teologije (CIT). Za Ashʿarīje, CIT je dovoljan za razumijevanje Boga, ali oni bi smatrali da bi SIT prikazan u ToN bio problematičan. Motivacija i metodologija lokaliziranja ili modificiranja Božje prirode ili atributa kako bi odgovarali današnjoj znanosti smatrala bi se teološki vrlo spronim oblikom scijentizma

A Sub-500 mu W Interface Electronics for Bionic Ears

This paper presents an ultra-low power current-mode circuit for a bionic ear interface. Piezoelectric (PZT) sensors at the system input transduce sound vibrations into multi-channel electrical signals, which are then processed by the proposed circuit to stimulate the auditory nerves consistently with the input amplitude level. The sensor outputs are first amplified and range-compressed through ultra-low power logarithmic amplifiers (LAs) into AC current waveforms, which are then rectified through custom current-mode circuits. The envelopes of the rectified signals are extracted, and are selectively sampled as reference for the stimulation current generator, armed with a 7-bit user-programmed DAC to enable patient fitting (calibration). Adjusted biphasic stimulation current is delivered to the nerves according to continuous inter-leaved sampling (CIS) stimulation strategy through a switch matrix. Each current pulse is optimized to have an exponentially decaying shape, which leads to reduced supply voltage, and hence similar to 20% lower stimulator power dissipation. The circuit has been designed and fabricated in 180nm high-voltage CMOS technology with up to 60 dB measured input dynamic range, and up to 1 mA average stimulation current. The 8-channel interface has been validated to be fully functional with 472 mu W power dissipation, which is the lowest value in the literature to date, when stimulated by a mimicked speech signal

A fully integrated autonomous power management system with high power capacity and novel MPPT for thermoelectric energy harvesters in IoT/wearable applications

This paper reports a fully integrated autonomous power management system for thermoelectric energy harvesting with application in batteryless IoT/Wearable devices. The novel maximum power point tracking (MPPT) algorithm does not require open circuit voltage measurement. The proposed system delivers 0.5 mA current with 1 V regulated output based on simulations, which is the highest output current for a fully integrated converter reported in the literature for ultra-low voltage applications, to the best knowledge of the authors. Regulated 1 V output can be achieved for load range >2 k Omega, and input voltage range >140 mV. The circuit has been implemented in UMC-180nm standard CMOS technology and simulated

Energy-aware bio-inspired spiking reinforcement learning system architecture for real-time autonomous edge applications

Mobile, low-cost, and energy-aware operation of Artificial Intelligence (AI) computations in smart circuits and autonomous robots will play an important role in the next industrial leap in intelligent automation and assistive devices. Neuromorphic hardware with spiking neural network (SNN) architecture utilizes insights from biological phenomena to offer encouraging solutions. Previous studies have proposed reinforcement learning (RL) models for SNN responses in the rat hippocampus to an environment where rewards depend on the context. The scale of these models matches the scope and capacity of small embedded systems in the framework of Internet-of-Bodies (IoB), autonomous sensor nodes, and other edge applications. Addressing energy-efficient artificial learning problems in such systems enables smart micro-systems with edge intelligence. A novel bio-inspired RL system architecture is presented in this work, leading to significant energy consumption benefits without foregoing real-time autonomous processing and accuracy requirements of the context-dependent task. The hardware architecture successfully models features analogous to synaptic tagging, changes in the exploration schemes, synapse saturation, and spatially localized task-based activation observed in the brain. The design has been synthesized, simulated, and tested on Intel MAX10 Field-Programmable Gate Array (FPGA). The problem-based bio-inspired approach to SNN edge architectural design results in 25X reduction in average power compared to the state-of-the-art for a test with real-time context learning and 30 trials. Furthermore, 940x lower energy consumption is achieved due to improvement in the execution time

Optimierung von kleinen Schirmgehäusen

Die Weiterentwicklung von Fahrerassistenzsystemen, wie z. B. Kombiinstrumente oder Navigationsgeräte, erfordern den Einsatz von leistungsstarken Mikrocontrollern und externen Speicherbausteinen, die über Datenleitungen mit hohen Taktraten angesteuert werden. Dabei ist immer öfter eine Schirmung auf oder innerhalb der Baugruppenebene notwendig. In diesem Beitrag wird das messtechnische Vorgehen zur Ermittlung der Schirmdämpfung gezeigt. Dann wird die Korrelation zur Simulation erläutert, die erforderlich ist, damit das Simulationsmodell zur Optimierung des Schirmgehäuses eingesetzt werden kann. Im Abschnitt Messaufbau wird die Einfügungsdämfungsmessung beschrieben sowie die Signalerzeugung mittels Kammgenerator. Das Störspektrum wurde in der Absorberhalle von 300 MHz bis 2,1 GHz ermittelt. Dabei lag der Prüfling auf einem Holztisch in 90 cm Höhe und zusätzlich auf 5 cm Styropor. Die Antenne war 1 m vom Prüfling entfernt und in einer Höhe von 1 m über dem Hallenboden angebracht. Dieser Aufbau lehnte an die Norm CISPR 25 an, die für Komponentenmessungen von Automobilelektronik verwendet wird (hierzu 2 Abb.: Abstrahlspektren bei elektrischer Anregung sowie Abstrahlspektren bei magnetischer Anregung). Es folgen Ergebnisse zur Ermittlung der Schirmdämfung, zur effektiven Schirmdämpfung und zur Simulation (hierzu 2 Abb.). Die Bestimmung der Schirmdämpfung von Kleingehäusen ist mit den herkömmlichen Messverfahren nur bedingt möglich, weil die Dimensionen der Antennen in der Regel die Gehäusedimensionen übersteigen. Es wurde eine Messung vorgestellt, bei der die anregende Struktur im Innern des Gehäuses untergebracht war. Die Bestimmung der Schirmeigenschaften des Gehäuses anhand der herkömmlichen Einfügungsdämpfung war nur bedingt möglich, deshalb wurde die Definition der effektiven Schirmdämpfung eingeführt

Design and implementation of a cloud computing service for finite element analysis

This paper presents an end-to-end discussion on the technical issues related to the design and implementation of a new cloud computing service for finite element analysis (FEA). The focus is specifically on performance characterization of linear and nonlinear mechanical structural analysis workloads over multi-core and multi-node computing resources. We first analyze and observe that accurate job characterization, tuning of multi-threading parameters and effective multi-core/node scheduling are critical for service performance. We design a “smart” scheduler that can dynamically select some of the required parameters, partition the load and schedule it in a resource-aware manner. We can achieve up to 7.53× performance improvement over an aggressive scheduler using mixed FEA loads. We also discuss critical issues related to the data privacy, security, accounting, and portability of the cloud service.European Commission ; IBM Shared University Research (SUR) program ; TÜBİTAK ; IBM PhD Fellowship awardpost-prin

BNP shows myocardial injury earlier than Troponin-I in experimental carbon monoxide poisoning

OBJECTIVE: In this study, our purpose was to determine whether plasma BNP level can be useful or not in determining the severity of myocardial injury formed by CO poisoning and to compare plasma BNP level with serum cTnI level. MATERIALS AND METHODS: In the study, 46 female Wistar Albino rats were used. Rats were divided into four groups, one control group and three poisoning groups. The mixture of pure CO and air was injected for 60 minutes to provide 3000 ppm CO concentration. Blood samples of groups were collected to measure COHb, BNP and cTnI levels. Blood samples of poisoning groups were collected at the 1st, 6th and 12th hours after poisoning. After biochemical procedures, findings were analysed statistically and compared with each other. RESULTS: Eight rats which died in poisoning groups were excluded and 38 rats were evaluated. BNP levels were high in all poisoning groups compared to control group and the difference between them was statistically significant (p < 0.05). cTnI levels were high in 6th and 12th hours poisoning groups compared to control and 1st hour group but only 12th hour group had statistically significant difference (p < 0.05). A statistically positive relation was established between BNP and cTnI levels in 6th and 12th hour groups (R: 0.76 - p < 0.05 - n:38). CONCLUSIONS: It was found that BNP levels increased earlier than cTnI levels in acute severe CO poisoning. BNP levels of the cases which were determined to have increased cTnI levels showing myocardial injury increased as well. BNP can show myocardial injury and its severity in acute CO poisoning

Acute diverticulitis in immunocompromised patients: evidence from an international multicenter observational registry (Web-based International Register of Emergency Surgery and Trauma, Wires-T)

Background: Immunocompromised patients with acute diverticulitis are at increased risk of morbidity and mortality. The aim of this study was to compare clinical presentations, types of treatment, and outcomes between immunocompromised and immunocompetent patients with acute diverticulitis. Methods: We compared the data of patients with acute diverticulitis extracted from the Web-based International Registry of Emergency Surgery and Trauma (WIRES-T) from January 2018 to December 2021. First, two groups were identified: medical therapy (A) and surgical therapy (B). Each group was divided into three subgroups: nonimmunocompromised (grade 0), mildly to moderately (grade 1), and severely immunocompromised (grade 2). Results: Data from 482 patients were analyzed—229 patients (47.5%) [M:F = 1:1; median age: 60 (24–95) years] in group A and 253 patients (52.5%) [M:F = 1:1; median age: 71 (26–94) years] in group B. There was a significant difference between the two groups in grade distribution: 69.9% versus 38.3% for grade 0, 26.6% versus 51% for grade 1, and 3.5% versus 10.7% for grade 2 (p &lt; 0.00001). In group A, severe sepsis (p = 0.027) was more common in higher grades of immunodeficiency. Patients with grade 2 needed longer hospitalization (p = 0.005). In group B, a similar condition was found in terms of severe sepsis (p = 0.002), quick Sequential Organ Failure Assessment score &gt; 2 (p = 0.0002), and Mannheim Peritonitis Index (p = 0.010). A Hartmann’s procedure is mainly performed in grades 1–2 (p &lt; 0.0001). Major complications increased significantly after a Hartmann’s procedure (p = 0.047). Mortality was higher in the immunocompromised patients (p = 0.002). Conclusions: Immunocompromised patients with acute diverticulitis present with a more severe clinical picture. When surgery is required, immunocompromised patients mainly undergo a Hartmann’s procedure. Postoperative morbidity and mortality are, however, higher in immunocompromised patients, who also require a longer hospital stay
