LIFU for major depressive disorder - Targeting the neural networks of depression

LIFU for major depressive disorder - Targeting the neural networks of depression Tiago Costa, Assistant Professor at the Department of Microelectronics, Delft University of Technology, discusses opportunities surrounding low-intensity focused ultrasound in the treatment of major depressive disorder in a minimally invasive manner. Major depressive disorder (MDD) is a prevalent and debilitating mental health condition affecting millions worldwide. While various treatment options exist, including medication and psychotherapy, a significant proportion of individuals with MDD do not achieve full remission or experience adverse side effects from existing treatments. Consequently, there is a need for innovative and effective therapeutic approaches to address this complex disorder. One emerging and promising area of research is the use of low-intensity focused ultrasound (LIFU) to treat major depressive disorder. LIFU is a non-invasive technique that utilises ultrasound waves at lower intensities compared to high-intensity focused ultrasound (HIFU), which is used for the thermal ablation of tissue. By focusing these ultrasound waves on specific brain regions, LIFU has shown potential in modulating neural activity and potentially alleviating depressive symptoms.

The chip designed as an analog front-end for the detectors using scintillation crystals NaI(Tl) or CsI(Tl) coupled with a SiPM photosensor.The chip can be used to build multichannel systems in such fields as nuclear science, medical imaging and homeland security.

Framework for High-Performance Video Acquisition and Processing in MTCA.4 Form Factor

The presented framework enables capturing video streams from cameras with a Camera Link interface. It is designed for scalable high-reliability industrial and scientific applications. The solution performs data capture, optionally processing it, and delivers it to a host CPU. It consists of an MTCA.4-compliant frame grabber, its firmware, and a set of software components supporting several different cameras. The framework is focused on Xilinx 7-Series field-programmable gate array (FPGA) circuits. These have I/O pins fast enough to deserialize the Camera Link streams without use of any external components. The reference implementation runs on a hardware platform composed of a dual-slot FMC carrier module equipped with a modern Artix-7 FPGA and up to two Camera Link pass-through modules. The video stream is written to the host computer memory by a custom scatter-gather direct memory access (DMA) engine developed at the Department of Microelectronics and Computer Science (DMCS) of Lodz University of Technology. The framework also includes complete software support consisting of a Linux device driver, application programming interface libraries as well as console and graphical user applications. The proposed video acquisition solution is the world's first Camera Link frame grabber for the MTCA.4 architecture. It enables collecting data from the camera using the top performance 80-bit Camera Link interface, offering 6.8 Gb/s of raw image data throughput. The solution was tested with a number of commercially available cameras.

Human Machine Interface for Data Acquisition Systems Applied in High Energy Physics

Nowadays high energy physics scientists build and design systems that are complex in terms of the huge amount of subsystems and individual components. A single subsystem may consist of a few tens of thousands digital and analogue channels and sensors. As a result, the data rates captured in modern systems may result in gigabytes per second. Complex systems could generate various alarms and provide other diagnostic information. Consequently, a huge number of variables are needed to control and monitor the system. It could be a real challenge to provide access to all alarms and diagnostic information in systems composed of thousands of channels. In this sense, it is necessary to develop a Human Machine Interfaces (HMI) that will be simple enough to describe a complex system and detailed enough to present all the relevant information to the operators. The purpose of this paper is to describe and propose an HMI scheme able to obtain and present data from High Energy Physics systems. The purpose of this paper is to evaluate HMI for complex systems. The prototype HMI described is based on the demonstration PXIe-based Neutron Flux Monitor (NFM) developed by the Department of Microelectronics and Computer Science. This NFM is going to provide essential information for plasma operation in the ITER plant. The HMI involves a Graphical User Interface and an Alarm Management Scheme, all based on the Experimental Physics and Industrial Control System (EPICS) framework. The Graphical User Interface (GUI) includes the use of several tools provided by the Control System Studio as well as JavaScript, rules and actions to dynamically present data to the operators. In regards to alarm management, a scheme is proposed to efficiently handle alarms by presenting the relevant information and controls to quickly react to alarms.

Some metal oxides and their applications for creation of Microsystems (MEMS) and Energy Harvesting Devices (EHD)

This is a review of a part of the work of the Technological Design Group at Technical University of Sofia, Faculty of Electronic Engineering and Technologies, Department of Microelectronics. It is dealing with piezoelectric polymer materials and their application in different microsystems (MEMS) and Energy Harvesting Devices (EHD), some organic materials and their applications in organic (OLED) displays, some transparent conductive materials etc. The metal oxides Lead Zirconium Titanate (PZT) and Zinc Oxide (ZnO) are used as piezoelectric layers - driving part of different sensors, actuators and EHD. These materials are studied in term of their performance in dependence on the deposition conditions and parameters. They were deposited as thin films by using RF Sputtering System. As technological substrates, glass plates and Polyethylenetherephtalate (PET) foils were used. For characterization of the materials, a test structure, based on Surface Acoustic Waves (SAW), was designed and prepared. The layers were characterized by Fourier Transform Infrared spectroscopy (FTIR). The piezoelectric response was tested at variety of mechanical loads (tensile strain, stress) in static and dynamic (multiple bending) mode. The single-layered and double-layered structures were prepared for piezoelectric efficiency increase. A structure of piezoelectric energy transformer is proposed and investigated.

New Thick-Film Microwave Elements for Microwave Integrated Circuits

The realisation of microwave integrated circuits consisting of numerous elements and components, both passive and active, takes place in steps. Initially, experimental constituent elements are designed and constructed, and only after it is found that they satisfy the operating conditions, can they be integrated into a sub-system. As a result of this we obtain complicated Microwave Integrated Circuits (MICs). Initially however one has to construct basic MIC elements such as: resonators, filters, couplings, Y branch joints, circulators, etc. During research over several years carried out at the Microelectronics Department, Institute of Electronics, of the Mining and Metallurgical University of Kraków and devoted to the application of thick-film technology to MIC, the authors have devised and constructed several microwave elements using strip-lines and this paper reports of the results of their studies.Pastes produced by DU PONT/USA were used. New mathematical models for designing thick-film microwave elements have been elaborated using computer techniques. These programmes have differed from analogous ones for MIC realized by thin-film technology can be adapted, after certain modifications, to the realisation of MIC. The authors have introduced new technological operations, not used so far, to the technological process. This has made possible the production of thick-film microwave elements with parameters comparable to those obtained in thin-film technology.
