- The future of cellular radio ICs lies in the integration of an ever-increasing number of bands and channel bandwidths. This paper presents a transceiver together with the associated discrete front-end components. The transceiver supports 4 EDGE bands and 9 WCDMA bands (l-VI and Vlll-X), while the radio can be configured to simultaneously support the 4 EDGE bands and up to 5 WCDMA bands: 3 high bands (HB) and 2 low bands (LB). The RX is a SAW-less homodyne composed of a main RX and a diversity RX. To reduce package complexity with so many bands, we chose to minimize the number of ports by using single-ended RF interfaces for both RX and TX. This saves seve ral package pins, but requires careful attention to grounding. The main RX has 8 LNA ports and the diversity RX has 5, with some LNAs supporting multiple bands. On the TX side, 2 ports are used for all EDGE bands and 4 for the WCDMA bands.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Det är förödande att sänka kraven på ambulanspersonal. Därför efterlyser vi nationella riktlinjer och beslut som tydligt anger en lägsta utbildningsnivå för anställning inom ambulanssjukvården, skriver Nätverket för utbildning av ambulanssjuksköterskor i en slutreplik.

A Top-Down Approach for a Synthetic Autobiographical Memory System

Ingår i: BIOMIMETIC AND BIOHYBRID SYSTEMS, LIVING MACHINES 2015. - Cham : Springer. - 9783319229799 - 9783319229782 ; , s. 280-292

- Autobiographical memory (AM) refers to the organisation of one's experience into a coherent narrative. The exact neural mechanisms responsible for the manifestation of AM in humans are unknown. On the other hand, the field of psychology has provided us with useful understanding about the functionality of a bio-inspired synthetic AM (SAM) system, in a higher level of description. This paper is concerned with a top-down approach to SAM, where known components and organisation guide the architecture but the unknown details of each module are abstracted. By using Bayesian latent variable models we obtain a transparent SAM system with which we can interact in a structured way. This allows us to reveal the properties of specific sub-modules and map them to functionality observed in biological systems. The top-down approach can cope well with the high performance requirements of a bio-inspired cognitive system. This is demonstrated in experiments using faces data.

A 28-nm FD-SOI 115-fs Jitter PLL-Based LO System for 24-30-GHz Sliding-IF 5G Transceivers
- 2018

Ingår i: IEEE Journal of Solid-State Circuits. - 0018-9200. ; 53:7, s. 1988-2000

Tidskriftsartikel (refereegranskat)abstract
- A system for local oscillator (LO) signal generation in 5G millimeter-wave (mmW) multi-antenna transceivers is presented. The system is modular with one phase locked loop (PLL) per antenna element transceiver, and a test circuit implemented in 28-nm fully depleted silicon on insulator (FD-SOI) CMOS features two such PLLs and a 491.52 MHz crystal oscillator (XO) generating a common frequency reference. A fractional-N architecture is employed to achieve high-frequency resolution, and the quantization noise is reduced using a novel frequency divider, which achieves full integer resolution while still using a pre-scaler. The system covers the 3rd Generation Partnership Project (3GPP) bands n257 and n258, achieved by a digital coarse tuning of the voltage-controlled oscillator (VCO). The chip area of each PLL is 0.11 mm², and 0.029 mm² for the XO. The total power consumption of the system is 35 mW, where each PLL consumes 15.4 mW and the XO consumes 0.84 mW. The total rms jitter from 20-kHz to 500-MHz offset for a 26-GHz carrier is just 115 fs, corresponding to an FOMj of -244 dB, which is the best reported figure for a fractional-N PLL above 15 GHz. The error-vector magnitude (EVM) due to phase noise is -34.6 dBc using an orthogonal frequency-division multiplexing (OFDM) signal with 120-kHz sub-carrier spacing, sufficient to support 256 QAM.

Innovationer i vårdens vardag: De små stegens väg till förändring
- 2007
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Tillitsfulla relationer mellan vårdpersonal, administratörer och politiker har en avgörande betydelse för vårdens omställning och det förnyelsearbete som bedrivs. Dessa relationer behöver systematiseras, stödjas för att fyllas med utvecklingskraft. Organisationer som medvetet satsar på att bygga dessa relationer för att bedriva verksamhet skapar innovationer i små steg”. Dessa tankar blev vägledande i arbetet med ett aktionsforskningsprojekt om framtidens närsjukvård i Västra Skaraborg. Analysen av det treåriga samarbetet visar på betydelsen av en pågående verksamhetsutveckling inifrån, baserad på vårdpersonalens egna erfarenheter och kunskaper om sin praktik. I en regional utvecklingskoalition med vårdens olika intressenter kunde arbetsformer, aktiviteter, mötesarenor etc. ta form för att underlätta och förnya samarbetet runt patienten. Erfarenheterna kan nu ligga till grund för fortsatt verksamhetsutveckling. Boken riktar sig till dig som arbetar med eller är intresserad av utvecklingsarbete av hälso- och sjukvårdsverksamhet. Boken kan läsas av både politiker, administratörer och vårdpersonalen då förmågan till samarbete mellan olika aktörer är ett av bokens huvudbudskap. Den är också lämplig för grundutbildning och fortbildning av vårdpersonal och hälso- och sjukvårdsadministratörer samt för kurser i organisationsutveckling.

- BackgroundChildhood cancer predisposition (ChiCaP) syndromes are increasingly recognized as contributing factors to childhood cancer development. Yet, due to variable availability of germline testing, many children with ChiCaP might go undetected today. We report results from the nationwide and prospective ChiCaP study that investigated diagnostic yield and clinical impact of integrating germline whole-genome sequencing (gWGS) with tumor sequencing and systematic phenotyping in children with solid tumors.MethodsgWGS was performed in 309 children at diagnosis of CNS (n = 123, 40%) or extracranial (n = 186, 60%) solid tumors and analyzed for disease-causing variants in 189 known cancer predisposing genes. Tumor sequencing data were available for 74% (227/309) of patients. In addition, a standardized clinical assessment for underlying predisposition was performed in 95% (293/309) of patients.FindingsThe prevalence of ChiCaP diagnoses was 11% (35/309), of which 69% (24/35) were unknown at inclusion (diagnostic yield 8%, 24/298). A second-hit and/or relevant mutational signature was observed in 19/21 (90%) tumors with informative data. ChiCaP diagnoses were more prevalent among patients with retinoblastomas (50%, 6/12) and high-grade astrocytomas (37%, 6/16), and in those with non-cancer related features (23%, 20/88), and ≥2 positive ChiCaP criteria (28%, 22/79). ChiCaP diagnoses were autosomal dominant in 80% (28/35) of patients, yet confirmed de novo in 64% (18/28). The 35 ChiCaP findings resulted in tailored surveillance (86%, 30/35) and treatment recommendations (31%, 11/35).InterpretationOverall, our results demonstrate that systematic phenotyping, combined with genomics-based diagnostics of ChiCaP in children with solid tumors is feasible in large-scale clinical practice and critically guides personalized care in a sizable proportion of patients.
