This paper presents a receiver front end with improved blocker handling implemented in a 65-nm CMOS technology. Since close-in blockers are challenging to reject at RF, the receiver features a baseband (BB) notch filter, which effectively sinks close-in blocker current directly from the output of an LNTA and passive mixer structure. The notch-filter frequency can be tuned to match the blocker offs

Background: Late effects induced by radiotherapy (RT) are of great concern for mediastinal Hodgkin’s lymphoma (HL) patients and it is therefore important to reduce normal tissue dose. The aim of this study was to investigate the impact on the normal tissue dose and target coverage, using various combinations of intensity modulated proton therapy (IMPT), volumetric modulated arc therapy (VMAT) and

Upon ischaemic stroke, brain-resident and peripheral immune cells accumulate in the central nervous system (CNS). Interestingly, these cells express pattern specific to neurotransmitter receptors and, therefore, seem to be susceptible to neurotransmitter stimulation, potentially modulating their properties and functions. One of the principal neurotransmitters in the CNS, dopamine, is involved in t

By examining photographic depictions of subjects labeled as ‘intellectually disabled’, this article theorizes how photography performs the ideological function of producing narratives of historical progression. Recurrent representations of, on the one hand, a dark past of state institutionalization and repression and, on the other hand, the present as a time when intellectually disabled people are

Over the past years, the installations of Shallow Geothermal Energy (SGE) systems are increasing throughout Europe, and it is indicating that a specific and detailed legal framework is necessary. Towards this direction, this paper consists of an overview of legislation issues on SGE at European level, based on concise reviews from fourteen countries, i.e., Croatia, Cyprus, France, Greece, Italy, L

Borehole thermal resistance is both an important design parameter and a key performance characteristic of a ground heat exchanger. Another quantity that is particularly important for ground heat exchangers is the internal thermal resistance between the heat exchanger pipes. Both these resistances can be calculated to a high degree of accuracy by means of the well-known multipole method. However, t

There are still no accepted criteria for the selection of patients with nonpalpable testes for laparoscopy versus a primary surgical exploration. We here report our experience using routine laparoscopy in such patients. The aim was to determine whether laparoscopy should be the first operative intervention or follow an inguinal exploration. Included in the study were 61 boys with 69 nonpalpable te

Purpose: The aim of this report is to establish the frequency and type of complications of laparoscopy-aided gastrostomy in pediatric practice and to identify patients at risk for postoperative complications. Method: This is a follow-up study of 98 children with nutritional problems including inability to swallow, inadequate calorie intake in neurologically impaired children, patients with cystic

The authors report the case of a child born with a gastroschisis and an ileal atresia. After surgery, only 100 cm small bowel and the distal one third of his colon remained. Perianastomotic ulcers developed 6 years later. These were treated successfully with ranitidin, a treatment not previously reported in the literature. The authors conclude that treatment with ranitidin was successful in a pati
