Gıda ve çevresel kaynaklarda Salmonella'nın hızlı, güvenilir ve hassas tespiti, halk sağlığını korumak için çok önemlidir. LAMP yöntemi özel cihazlara ve deneyimli personele ihtiyaç duymaksızın uygulanabilecek bir yöntem olduğu için son yıllarda sıklıkla tercih edilmektedir. LAMP’ın, mikroakışkan cihazlarla kombine edilmesi sınırlı kaynakların olduğu durumlarda, hızlı tanı testleri için bir alternatifdir. Salmonella spp. tespiti için, üç boyutlu yazıcıda biyouyumlu PLA filament kullanılarak mikroakışkan çip oluşturularak, ilmiğe dayalı izotermal amplifikasyon yöntemi ile kombine edilmesi amaçlanmıştır. Mikroakışkan çipler CATIA V5 programı kullanılarak tasarlandı (Çip boyutları 15x12.5x2.4 mm, kanal çapı 850 µm) ve PLA filament kullanılarak 3B yazıcıda üretildi. Salmonella spesifik LAMP reaksiyonları için InvA geni seçildi. Mikroakışkan çipler için kuru ısı bloğu kullanıldı ve LAMP protokolü 65℃’da 30 dak.’ydı. Testin duyarlılık, özgüllük, PPD ve NPD ölçümleri gerçekleştirildi.
Kültür yöntemi ile Salmonella pozitif saptanan 25 pozitif numune arasında, mikrosantrifüj tüpünde uygulanan LAMP reaksiyonu ile sadece bir numunede yalancı negatif sonuc saptanmışken, mikroakışkan çip üstünde uygulanan LAMP reaksiyonunda ise iki numune yalancı negatif olarak tespit edildi.
Sonuç olarak; verilerimiz LAMP reaksiyonları ile mikroakışkan çip teknolojisinin birleştirilebileceğini, üç boyutlu yazıcıların bu mikroakışkan çiplerin üretimi sırasında kullanılabileceğini bize göstermiştir.

<p>A source-degenerated Schmitt-trigger logic is proposed. Based on this architecture, basic logic-gate architectures, ring oscillators, and edge-sensitive D-type flip-flops were fabricated using low-voltage p-channel organic thin-film transistors and integrated thin-film carbon resistors on flexible polymeric substrates. Mathematical analysis of this logic architecture indicates improved stability against charge-carrier-mobility degradation. A small-signal gain of 83 dB and a noise margin of 92 % of half the supply voltage have been measured. Owing to the intrinsic positive-feedback loop of the source-degenerated Schmitt-trigger logic, the design of the D-flip-flop enables a substantially smaller footprint and a considerably lower energy dissipation compared to previously reported unipolar organic-TFT-based D-flip-flop architectures. </p>

Published: November 2022

<p>Sound source localization is used in various applications such as industrial noise-control, speech detection in mobile phones, speech enhancement in hearing aids and many more. Newest video conferencing setups use sound source localization. The position of a speaker is detected from the difference in the audio waves received by a microphone array. After detection the camera focuses onto the location of the speaker. The human brain is also able to detect the location of a speaker from auditory signals. It uses, among other cues, the difference in amplitude and arrival time of the sound wave at the two ears, called interaural level and time difference. However, the substrate and computational primitives of our brain are different from classical digital computing. Due to its low power consumption of around 20 Watts and its performance in real time the human brain has become a great source of inspiration for emerging technologies. One of these technologies is neuromorphic hardware which implements the fundamental principles of brain computing identified until today using \ac{CMOS} technologies and new devices. In this work we propose the first neuromorphic closed-loop robotic system that uses the interaural time difference for sound source localization in real time. Our system can successfully locate sound sources such as human speech. In a closed-loop experiment, the binaural robotic platform turned immediately into the direction of the sound source with a turning velocity linearly proportional to the angle difference between sound source and pan-tilt unit. After this initial turn, the robotic platform remains at the direction of the sound source. Even though the system only uses very few resources of the available hardware and was only tuned by hand it already reaches performances comparable to other neuromorphic approaches. The sound source localization system presented in this article brings us one step closer towards neuromorphic event-based systems for robotics and embodied computing.</p>

<p>Machine learning and artificial intelligence are two key emerging technologies in computer science that require vast amounts of data for a meaningful application. The requirement of such a large dataset is usually met by pooling data from various sources, which is often difficult to implement in practice due to strict data privacy constraints. Peer-to-Peer federated learning is a distributed machine learning paradigm with a primary goal of learning a well-performing global model by collaboratively learning a shared model at different data hubs without the need of sharing data. Due to its immense practical applications, there is a growing attention towards various challenges of efficient fed- erated learning including communication efficiency, assumptions on connectivity, data heterogeneity, enhanced privacy, etc. In this paper, we address the communication efficiency of Peer-to-Peer federated learning, modeling it using a graph theoretical frame- work. We show that one can draw from a range of graph-based algorithms to construct an efficient communication algorithm on a connected network, thereby matching the inference efficiency of centralized federated learning as well as that of a consolidated dataset. We conduct experiments with varied graph formations and sizes to validate our claims. </p>
High-density and low-crosstalk multilayer silicon nitride waveguide superlattices with air gaps

Published: November 2022

<p>High-density and low-crosstalk waveguide arrays are critical components in optical phased arrays (OPAs) and are widely used in solid-state light detection and ranging (LiDAR). In this work, silicon nitride waveguide superlattices with air gaps are proposed and analyzed theoretically. Mode analysis shows that the introduced air gaps beside the waveguide help shorten the skin depth of the evanescent field and increase the effective index<br>
range of the waveguide under single mode conditions. Lower crosstalk is demonstrated between a pair of waveguides with air gaps compared with those without air gaps. On this basis, a waveguide superlattice with air gaps is designed by combining the eigenmode expansion method and particle swarm optimization. The crosstalk of the waveguide superlattice is optimized to -24.3 dB when the waveguide pitch is 0.9 µm, the propagation length is 1 mm, and the wavelength is 905 nm. The crosstalk is still below -22.4 dB under the typical process variations and over the wavelength range of 890 nm - 920 nm. Therefore, the proposed air-gap waveguide superlattices with high density and low crosstalk offer opportunities to improve the beam steering performance of OPA chips in the shortwave infrared (SWIR) waveband.<br>

Published: November 2022

In the turning process, the surface roughness is affected by cutting parameters such as cutting speed, depth of cut, feed rate, and so on. However, there is not much information about the relationship or interaction between cutting parameters and the resulting surface roughness. This study aimed to examine the effect of cutting parameters on the surface roughness value of low carbon steel. This research was conducted experimentally using a conventional lathe with a HSS insert without the use of cutting fluids. It was concluded that the cutting parameters had a significant effect on the surface roughness. The lowest surface roughness value was obtained at 280 rpm spindle speed, 0.5 mm depth of cut and 0.2 mm/rev. feed rate with a roughness value of 2.968 µm. The contribution of each parameter to the surface roughness were 42.2% of spindle speed, 10% of depth of cut and 20.3% of feed rate respectively.

<p><strong>This study aims to determine the impact of the Pan Arabism Movement initiated by Gamal Abdul Nasser in 1956-1970 on the religious identity, language, and culture of the Egyptian Coptic society. The method used in this study is a library research method by collecting data from various sources, then analyzing and describing the results of data analysis based on the cultural theory of the Egyptian Coptic society according to Malaty, 1993 and the Pan Arabism Policy theory according to Elie and Onn Winckler Podeh, 2004. Pan Arabism had an identity-changing impact on Egyptian Coptic society. In religion, the freedom to guard and protect their places of worship was restricted and the existence of the Coptic religion began to diminish. In language, the use of Coptic is increasingly restricted and Coptic is almost extinct because it is only used during worship as a liturgical language. Meanwhile, in cultural field, there was an ideological shift in Egyptian society and Egypt became more identical with Arab culture.</strong></p><p><strong><em>Keyword</em></strong> - <em>Pan Arabism, Gamal Abdul Nasser, Identity of the Egyptian Coptic Society.</em></p>

A Maximum Likelihood Calibration of the Tip of the Red Giant Branch Luminosity from High Latitude Field Giants Using Gaia Early Data Release 3 Parallaxes
Authors: Li Siyang , Casertano Stefano , Riess Adam G. 
Published: November 2022

Abstract
The calibration of the tip of the red giant branch (TRGB) in the I band has a direct role in determinations of the Hubble constant, a subject of recent interest due to the discrepancy between direct and indirect estimates of its value. We present a maximum likelihood method designed to obtain an independent calibration of the brightness of TRGB using Gaia parallaxes from the Early Data Release 3 (EDR3) of Milky Way field giants at high Galactic latitude. We adopt simple parameterizations for the Milky Way stellar luminosity function and density law and optimize the likelihood of the observed sample as a function of those parameters. Using parameters to partially constrain the luminosity function from other galaxies similar to the Milky Way for which high-quality TRGB data are available, we find values of the TRGB magnitude of

(stat) ± 0.09 (sys) mag, where the systematic uncertainty covers the range of shape parameters found in our Milky Way sample and in reference galaxies. While APASS Data Release 9 all-sky photometry is insufficient to provide a reliable constraint on the shape of the Milky Way luminosity function, we estimate that the photometry from Gaia Data Release 3 (mid-2022) will allow better constraints on the shape, and lower statistical uncertainties on the tip by a factor of 3. With the expected releases of improved parallax measurements from Gaia, the method of calibrating the TRGB luminosity from field giants is expected to reach ∼0.01 mag uncertainty, which is an important step toward a precise TRGB-based determination of the Hubble constant.

Published: November 2022

Abstract
We present a novel method to accurately measure the galaxy stellar mass function (GSMF) based upon the Photometric objects Around Cosmic webs (PAC) method developed in our first paper (Paper I) of the series. The method allows us to measure the GSMF to a lower-mass end that is not accessible to the spectroscopic sample used in the PAC. Compared with Paper I, the current measurement of GSMF is direct and model independent. We measure the GSMFs in the redshift ranges of z
