A fault tolerant CSA in QCA technology for IoT devices.

Sci Rep

January 2025

Department of Computer Engineering, Faculty of Engineering, Bu-Ali Sina University, Hamedan, Iran.

According to recent research, with the ever-increasing use of Internet of Things (IoT) devices, there has arisen an ever-growing need for high-performance yet low-power circuits that can efficiently process information. Quantum-dot Cellular Automata (QCA) has emerged as a promising alternative to conventional complementary metal-oxide-semiconductor (CMOS) technology due to its great potential in digital design at nanoscale levels on account of very low power consumption and very high processing speed. However, QCA circuits are inherently prone to faults due to variations in manufacturing processes and due to the influence of environmental factors.

Massive subcutaneous filariosis by in beech marten () in Italy.

Parasite Epidemiol Control

February 2025

Veterinary Medicine and Animal Production Department, Naples University, 8 Via Mezzocannone, 80138 Naples, Italy.

The beech marten () is a small-size mustelid endangered according to the IUCN Red List. Despite the plethora of parasites potentially affecting its population decline, subcutaneous filarioids are occasionally reported in martens and their competent arthropod vectors are to date unknown. Therefore, from January 2023 to August 2024, this study investigated the presence of subcutaneous filarioids and ectoparasites of road-killed beech martens ( = 7) from southwestern Italy.

J Comput Chem

January 2025

Department of Inorganic Chemistry, Faculty of Chemistry and Petroleum Sciences, Bu-Ali Sina University, Hamedan, Iran.

The strength and cooperative energy of chalcogen and dihydrogen bonds in some ABC triad systems of the types XHTe…NCH…HY (X = F, Cl, Br, I, H; Y = Li, Na, BeH, MgH) and FHCh…NCH…HNa (Ch = Te, Se, S) were computed and compared at several levels of theory. All resulting data showed that the strengths of chalcogen (Te…N) and dihydrogen (H…H) bonds increase in the order of H < I < Br < Cl < F, and Be < Mg < Li < Na, respectively. Then, the comparison of data for the FHTe…NCH…HY, FHSe…NCH…HNa, and FHS…NCH…HNa triads indicated that the interaction, stabilization, and cooperativity energies decrease in the order of Te > Se > S.

Background: Posterior tibialis tendon dysfunction (PTTD) is a debilitating condition that leads to biomechanical changes, for which foot orthoses are often prescribed to attenuate. There is a need to improve the ability to predict these biomechanical alterations, determine the biomechanical effectiveness of foot orthoses, and anticipate their effects on individuals with PTTD during gait.

Research Question: Is the supination resistance test (SRT) reliable, and capable of predicting foot and ankle biomechanics, as well as the biomechanical effects of foot orthoses in individuals with PTTD during gait?

Methods: Twenty-one individuals with PTTD participated with supination resistance measured over two sessions.

In this study, we present the design, synthesis, and utilization of a covalent triazine framework (CTF) formed by the condensation of , , -tris(4-(aminomethyl)benzyl)-1,3,5-triazine-2,4,6-triamine and 2,4,6-tris(4-formylphenoxy)-1,3,5-triazine on which silica is immobilized (TPT-TAT/silica) as an innovative catalyst for porphyrins synthesis. Under solvothermal conditions, the condensation of triamine and trialdehyde precursors led to the formation of a covalent triazine framework (CTF) with a high nitrogen content. The resulting CTF is characterized by its extensive porosity and elevated nitrogen levels, which are critical for the creation of catalytic active sites.

High-performance modified LDH for green one-pot synthesis of pyrido[2,3-]pyrimidines.

Heliyon

January 2025

Department of Organic Chemistry, Faculty of Chemistry and Petroleum Sciences, Bu-Ali Sina University, Hamedan, Iran.

This study introduces a new nano catalyst tailored for the eco-friendly synthesis of pyrido[2,3-]pyrimidine via a three-component one-pot reaction involving benzaldehydes, malononitrile, and uracil. To achieve this objective, we anchored copper acetate onto the surface of layered double hydroxides modified with 1,3‑benzenedisulfonyl amide (BDSA) (LDH@PTRMS@BDSA@Cu(NO)), which exhibited remarkable activity and selectivity. The main benefits of this method include high product yield, swift reaction times, straightforward purification, catalyst reusability, and the employment of a mild reaction process.

Tannic acid (TA), as a plant polyphenol, has many active sites for chelation with metals, so TA-oligomers (TA-Olig) were used for the first time as ligands on the surface of Ce-Mn-LDH to prepare the layered double hydroxide-based metal-organic framework (Ce-Mn-LDH@CPTMS@TA-Olig@Co-MOF = E) nanocomposite. In this regard, a homogeneous water/ethanol solution was prepared by sol-gel method using polyethylene glycol and ammonia solution, and then TA was converted into a set of oligomers in the presence of formaldehyde. In the next step, Ce-Mn-LDH was prepared in a ratio of 1 : 4 of Ce to Mn, modified with 3-chloropropylmethoxysilane, functionalized by TA-Olig, and then cobalt salt was used to prepare E.
