Abstract: Background Natalizumab (NAT) has a strong impact on disease activity of aggressive pediatric multiple sclerosis (MS), with no difference in safety profile compared to adult MS. However, available data are limited by short follow-up. Our aim was to report long-term follow-up data (up to 11 years) of a large Italian pediatric MS cohort treated with NAT. Materials and methods We retrospectively collected data of pediatric MS patients treated with NAT included in a previous study and prospectively followed in Italian MS centers. We compared disease activity pre, during, and post-NAT and we performed survival analyses of time to evidence of disease activity (EDA) during NAT, time to reach EDA post-NAT, and time to NAT discontinuation. Results Ninety-two patients were included from 19 MS centers in Italy. At NAT initiation, cohort's characteristics were as follows: 55 females; 14.7 +/- 2.4 (mean +/- SD) years of age; 34 naive to disease modifying therapies; 1-year pre-NAT annualized relapse rate (ARR): 2.2 +/- 1.2; EDSS (median [IQR]): 2.5 [2.0-3.0]; gadolinium-enhancing lesions: 2 [1-5]; 41 JCV positives. During NAT treatment (61.9 +/- 35.2 mean infusions), ARR lowered to 0.08 +/- 0.23 (p < 0.001), EDSS score to 1.5 [1.0-2.5] at last infusion (p < 0.001), and 51% patients had EDA (21% after 6 months of rebaseline). No serious adverse events were reported. Forty-nine patients discontinued NAT, mainly due to PML concern; the majority (29/49) had disease reactivation in the subsequent 12 months, of which three with a clinical rebound. Conclusion NAT treatment maintains its high efficacy for a long time in pediatric MS patients, with no new safety issues.

Abstract: Background: Treatment with natalizumab once every 4 weeks is approved for patients with relapsing-remitting multiple sclerosis, but is associated with a risk of progressive multifocal leukoencephalopathy. Switching to extended-interval dosing is associated with lower progressive multifocal leukoencephalopathy risk, but the efficacy of this approach is unclear. We aimed to assess the safety and efficacy of natalizumab once every 6 weeks compared with once every 4 weeks in patients with relapsing-remitting multiple sclerosis. Methods: We did a randomised, controlled, open-label, phase 3b trial (NOVA) at 89 multiple sclerosis centres across 11 countries in the Americas, Europe, and Western Pacific. Included participants were aged 18–60 years with relapsing-remitting multiple sclerosis and had been treated with intravenous natalizumab 300 mg once every 4 weeks with no relapses for at least 12 months before randomisation, with no missed doses in the previous 3 months. Participants were randomly assigned (1:1), using a randomisation sequence generated by the study funder and contract personnel with interactive response technology, to switch to natalizumab once every 6 weeks or continue with once every 4 weeks. The centralised MRI reader, independent neurology evaluation committee, site examining neurologists, site backup examining neurologists, and site examining technicians were masked to study group assignments. The primary endpoint was the number of new or newly enlarging T2 hyperintense lesions at week 72, assessed in all participants who received at least one dose of assigned treatment and had at least one postbaseline MRI, relapse, or neurological examination or efficacy assessment. Missing primary endpoint data were handled under prespecified primary and secondary estimands: the primary estimand included all data, regardless of whether participants remained on the assigned treatment; the secondary estimand classed all data obtained after treatment discontinuation or study withdrawal as missing. Safety was assessed in all participants who received at least one dose of study treatment. Study enrolment is closed and an open-label extension study is ongoing. This study is registered with EudraCT, 2018-002145-11, and ClinicalTrials.gov, NCT03689972. Findings: Between Dec 26, 2018, and Aug 30, 2019, 605 patients were assessed for eligibility and 499 were enrolled and assigned to receive natalizumab once every 6 weeks (n=251) or once every 4 weeks (n=248). After prespecified adjustments for missing data, mean numbers of new or newly enlarging T2 hyperintense lesions at week 72 were 0·20 (95% CI 0·07–0·63) in the once every 6 weeks group and 0·05 (0·01–0·22) in the once every 4 weeks group (mean lesion ratio 4·24 [95% CI 0·86–20·85]; p=0·076) under the primary estimand, and 0·31 (95% CI 0·12–0·82) and 0·06 (0·01–0·31; mean lesion ratio 4·93 [95% CI 1·05–23·20]; p=0·044) under the secondary estimand. Two participants in the once every 6 weeks group with extreme new or newly enlarging T2 hyperintense lesion numbers (≥25) contributed most of the excess lesions. Adverse events occurred in 194 (78%) of 250 participants in the once every 6 weeks group and 190 (77%) of 247 in the once every 4 weeks group, and serious adverse events occurred in 17 (7%) and 17 (7%), respectively. No deaths were reported. There was one case of asymptomatic progressive multifocal leukoencephalopathy (without clinical signs) in the once every 6 weeks group, and no cases in the once every 4 weeks group; 6 months after diagnosis, the participant was without increased disability and remained classified as asymptomatic. Interpretation: We found a numerical difference in the mean number of new or newly enlarging T2 hyperintense lesions at week 72 between the once every 6 weeks and once every 4 weeks groups, which reached significance under the secondary estimand, but interpretation of statistical differences (or absence thereof) is limited because disease activity in the once every 4 weeks group was lower than expected. The safety profiles of natalizumab once every 6 weeks and once every 4 weeks were similar. Although this trial was not powered to assess differences in risk of progressive multifocal leukoencephalopathy, the occurrence of the (asymptomatic) case underscores the importance of monitoring and risk factor consideration in all patients receiving natalizumab.

Abstract: Summary Background Among asymptomatic patients with severe carotid artery stenosis but no recent stroke or transient cerebral ischaemia, either carotid artery stenting (CAS) or carotid endarterectomy (CEA) can restore patency and reduce long-term stroke risks. However, from recent national registry data, each option causes about 1% procedural risk of disabling stroke or death. Comparison of their long-term protective effects requires large-scale randomised evidence. Methods ACST-2 is an international multicentre randomised trial of CAS versus CEA among asymptomatic patients with severe stenosis thought to require intervention, interpreted with all other relevant trials. Patients were eligible if they had severe unilateral or bilateral carotid artery stenosis and both doctor and patient agreed that a carotid procedure should be undertaken, but they were substantially uncertain which one to choose. Patients were randomly allocated to CAS or CEA and followed up at 1 month and then annually, for a mean 5 years. Procedural events were those within 30 days of the intervention. Intention-to-treat analyses are provided. Analyses including procedural hazards use tabular methods. Analyses and meta-analyses of non-procedural strokes use Kaplan-Meier and log-rank methods. The trial is registered with the ISRCTN registry, ISRCTN21144362. Findings Between Jan 15, 2008, and Dec 31, 2020, 3625 patients in 130 centres were randomly allocated, 1811 to CAS and 1814 to CEA, with good compliance, good medical therapy and a mean 5 years of follow-up. Overall, 1% had disabling stroke or death procedurally (15 allocated to CAS and 18 to CEA) and 2% had non-disabling procedural stroke (48 allocated to CAS and 29 to CEA). Kaplan-Meier estimates of 5-year non-procedural stroke were 2·5% in each group for fatal or disabling stroke, and 5·3% with CAS versus 4·5% with CEA for any stroke (rate ratio [RR] 1·16, 95% CI 0·86–1·57; p=0·33). Combining RRs for any non-procedural stroke in all CAS versus CEA trials, the RR was similar in symptomatic and asymptomatic patients (overall RR 1·11, 95% CI 0·91–1·32; p=0·21). Interpretation Serious complications are similarly uncommon after competent CAS and CEA, and the long-term effects of these two carotid artery procedures on fatal or disabling stroke are comparable.

Abstract: Summary Background Opicinumab is a human monoclonal antibody against LINGO-1, an inhibitor of oligodendrocyte differentiation and axonal regeneration. Previous findings suggested that opicinumab treatment might enhance remyelination in patients with CNS demyelinating diseases. We aimed to assess the safety and efficacy of opicinumab in patients with relapsing multiple sclerosis. Methods We did a randomised, double-blind, placebo-controlled, dose-ranging, phase 2 study (SYNERGY) at 72 sites in 12 countries. Participants (aged 18–58 years) with relapsing multiple sclerosis (relapsing-remitting multiple sclerosis and secondary progressive multiple sclerosis with relapses) were randomised in a 1:2:2:2:2 ratio by an interactive voice and web response system to opicinumab 3 mg/kg, 10 mg/kg, 30 mg/kg, or 100 mg/kg, or placebo. An identical volume of study drug was administered intravenously once every 4 weeks. All participants self-administered intramuscular interferon beta-1a as background anti-inflammatory treatment once a week. The primary endpoint was the percentage of participants achieving confirmed disability improvement over 72 weeks, which was a multicomponent endpoint measured by the Expanded Disability Status Scale, the Timed 25-Foot Walk, the Nine-Hole Peg Test, and the 3 s Paced Auditory Serial Addition Test. The primary endpoint was analysed under intention-to-treat principles. This study is registered at ClinicalTrials.gov , number NCT01864148 . Findings Between Aug 13, 2013, and July 31, 2014, 419 patients were enrolled and randomly assigned either placebo (n=93) or opicinumab 3 mg/kg (n=45), 10 mg/kg (n=95), 30 mg/kg (n=94; one patient did not receive the assigned treatment), or 100 mg/kg (n=92). The last patient visit was on March 29, 2016. Confirmed disability improvement over 72 weeks was seen in 45 (49%) of 91 patients assigned to placebo, 21 (47%) of 45 assigned to opicinumab 3 mg/kg, 59 (63%) of 94 assigned to opicinumab 10 mg/kg, 59 (65%) of 91 assigned to opicinumab 30 mg/kg, and 36 (40%) of 91 assigned to opicinumab 100 mg/kg. A linear dose-response in the probability of confirmed disability improvement was not seen (linear trend test p=0·89). Adverse events occurred in 79 (85%) patients assigned placebo and in 275 (85%) assigned any dose of opicinumab. The most common adverse events of any grade in patients assigned any dose of opicinumab included influenza-like illness (140 [43%] with any dose of opicinumab vs 37 [40%] with placebo), multiple sclerosis relapses (117 [36%] vs 30 [32%]), and headache (51 [16%] vs 23 [25%]). Serious adverse events reported as related to treatment were urinary tract infection in one (1%) participant in the the placebo group, suicidal ideation and intentional overdose in one (1%) participant in the 30 mg/kg opicinumab group, bipolar disorder in one (1%) participant in the 100 mg/kg opicinumab group, and hypersensitivity in four (4%) participants in the 100 mg/kg opicinumab group. One patient in the opicinumab 30 mg/kg group died during the study due to a traffic accident, which was not considered related to study treatment. Interpretation Our findings did not show a significant dose-linear improvement in disability compared with placebo in patients with relapsing multiple sclerosis. Further studies are needed to investigate whether some subpopulations identified in the study might benefit from opicinumab treatment at an optimum dose. Funding Biogen.

Abstract: This paper presents a technique to regulate the bandwidth of digital phase-locked loops (PLLs), where a fully digital automatic control circuit, running in background, is used to desensitize loop gain from analog parameters. The method that is based on an adaptive least-mean-squares algorithm requires no injection of a training sequence, potentially degrading phase noise performance, and is suitable in particular for bang-bang PLLs, where the bandwidth depends on the input noise. The operating principle is first introduced and discussed with the help of an intuitive time-domain model, and the algorithm extension addressing the practical implementation issues associated with loop latency is then presented. The calibration circuit is embedded in a 65-nm CMOS digital PLL that achieves 400-fs integrated rms jitter with a power consumption of 4.5 mW. The algorithm enables digital programmability of loop bandwidth from 100 kHz to 2 MHz with an error below 1 dB between the theoretical and measured PLL noise transfer functions.

Abstract: Background: Few studies have investigated the experiences of patients around the conversion to secondary progressive multiple sclerosis (SPMS). ManTra is a mixed-method, co-production research project conducted in Italy and Germany to develop an intervention for newly-diagnosed SPMS patients. In previous project actions, we identified the needs and experiences of patients converting to SPMS via literature review and qualitative research which involved key stakeholders. Aims: The online patient survey aimed to assess, on a larger and independent sample of recently-diagnosed SPMS patients: (a) the characteristics associated to patient awareness of SPMS conversion; (b) the experience of conversion; (c) importance and prioritization of the needs previously identified. Methods: Participants were consenting adults with SPMS since ≤5 years. The survey consisted of three sections: on general and clinical characteristics; on experience of SPMS diagnosis disclosure (aware participants only); and on importance and prioritization of 33 pre-specified needs. Results: Of 215 participants, those aware of their SPMS diagnosis were 57% in Italy vs. 77% in Germany (p = 0.004). In both countries, over 80% of aware participants received a SPMS diagnosis from the neurologist; satisfaction with SPMS disclosure was moderate to high. Nevertheless, 28–35%obtained second opinions, and 48–56% reported they did not receive any information on SPMS. Participants actively seeking further information were 63% in Germany vs. 31% in Italy (p < 0.001). Variables independently associated to patient awareness were geographic area (odds ratio, OR 0.32, 95% CI 0.13–0.78 for Central Italy; OR 0.21, 95% CI 0.08–0.58 for Southern Italy [vs. Germany]) and activity limitations (OR 7.80, 95% CI 1.47–41.37 for dependent vs. autonomous patients). All pre-specified needs were scored a lot or extremely important, and two prioritized needs were shared by Italian and German patients: “physiotherapy” and “active patient care involvement.” The other two differed across countries: “an individualized health care plan” and “information on social rights and policies” in Italy, and “psychological support” and “cognitive rehabilitation” in Germany. Conclusions: Around 40% of SPMS patients were not aware of their disease form indicating a need to improve patient-physician communication. Physiotherapy and active patient care involvement were prioritized in both countries.

Abstract: Performance of FMCW generators based on DPLLs are significantly affected by the presence of spurs. The latter may originate from the inherent operation of the DPLL itself, when operated in Fractional-N mode, or by external aggressors via coupling paths. Moreover, non-linearities of the loop can result in a worsening of the spur level thus in a degradation of the generated frequency modulation. This paper provides an insight on spurs impact in PLL-based chirp generators for radar sensors. Three different scenarios are taken into account: fractional spurs arising from non linearities, spurs coupling to the output of the DPLL and coupling of the digital activity of the divider to the DCO. The analysis is performed by means of a time-domain model of the FMCW Radar transceiver for target detection, and the effect on the range FFT and on Doppler shift of the base-band signal is presented.

Abstract: This letter presents a 14-GHz digital-intensive phase modulator circuit, which is able to enforce an arbitrary carrier phase change in one sample of a 200-MHz clock. The architecture is based on a fractional-N bang–bang digital PLL exploiting an adaptive DCO-tuning requantizer, which mitigates the segmentation-induced nonlinearity of the DCO, and a novel deskewing circuit, which improves the EVM at high bit rates. The modulation error, expressed in terms of RMS value of the EVM, is below −42 dB for a 250-Mb/s 32-PSK modulated carrier. The phase modulator, integrated in a 28-nm CMOS process, consumes 31.5-mW power, achieving 0.13-nJ/bit energy consumption.

Abstract: Digital phase-locked loops (DPLLs) have been demonstrated to achieve excellent performance as fractional-N frequency synthesizers in the sub-6GHz range, but, when used in the mm-wave range, at 30GHz and above, they typically feature poor jitter-power trade-off. This paper presents a 30GHz fractional-N DPLL in 65nm low-power (LP) CMOS achieving 198fs integrated jitter at 35mW power. The DPLL based on a digital-to-time converter (DTC) combines: (i) sub-sampling bang-bang phase detection to reduce power consumption, (ii) a digital error correction to reduce DTC noise contribution, and (iii) a low-power wide-lock-range divide-by-six circuit to allow operation up to 34GHz.

Abstract: This paper describes a 15.6-18.2GHz fractional-N bang-bang digital PLL fabricated in 28nm CMOS. To compensate for the nonlinearity of the digital-to-time converter and reduce the level of fractional spurs, two alternative predistortion techniques are introduced. The adoption of those algorithms operating continuously in background is demonstrated to reduce the level of the in-band fractional spur at 300kHz from −20dBc to −57dBc and −63dBc, respectively. The fabricated PLL achieves FoM of −237.2dB.

Abstract: BACKGROUND: Although several disease-modifying treatments are available for relapsing multiple sclerosis, treatment effects have been more modest in progressive multiple sclerosis and have been observed particularly in actively relapsing subgroups or those with lesion activity on imaging. We sought to assess whether natalizumab slows disease progression in secondary progressive multiple sclerosis, independent of relapses.METHODS: ASCEND was a phase 3, randomised, double-blind, placebo-controlled trial (part 1) with an optional 2 year open-label extension (part 2). Enrolled patients aged 18-58 years were natalizumab-naive and had secondary progressive multiple sclerosis for 2 years or more, disability progression unrelated to relapses in the previous year, and Expanded Disability Status Scale (EDSS) scores of 3·0-6·5. In part 1, patients from 163 sites in 17 countries were randomly assigned (1:1) to receive 300 mg intravenous natalizumab or placebo every 4 weeks for 2 years. Patients were stratified by site and by EDSS score (3·0-5·5 vs 6·0-6·5). Patients completing part 1 could enrol in part 2, in which all patients received natalizumab every 4 weeks until the end of the study. Throughout both parts, patients and staff were masked to the treatment received in part 1. The primary outcome in part 1 was the proportion of patients with sustained disability progression, assessed by one or more of three measures: the EDSS, Timed 25-Foot Walk (T25FW), and 9-Hole Peg Test (9HPT). The primary outcome in part 2 was the incidence of adverse events and serious adverse events. Efficacy and safety analyses were done in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01416181.FINDINGS: Between Sept 13, 2011, and July 16, 2015, 889 patients were randomly assigned (n=440 to the natalizumab group, n=449 to the placebo group). In part 1, 195 (44%) of 439 natalizumab-treated patients and 214 (48%) of 448 placebo-treated patients had confirmed disability progression (odds ratio [OR] 0·86; 95% CI 0·66-1·13; p=0·287). No treatment effect was observed on the EDSS (OR 1·06, 95% CI 0·74-1·53; nominal p=0·753) or the T25FW (0·98, 0·74-1·30; nominal p=0·914) components of the primary outcome. However, natalizumab treatment reduced 9HPT progression (OR 0·56, 95% CI 0·40-0·80; nominal p=0·001). In part 1, 100 (22%) placebo-treated and 90 (20%) natalizumab-treated patients had serious adverse events. In part 2, 291 natalizumab-continuing patients and 274 natalizumab-naive patients received natalizumab (median follow-up 160 weeks [range 108-221]). Serious adverse events occurred in 39 (13%) patients continuing natalizumab and in 24 (9%) patients initiating natalizumab. Two deaths occurred in part 1, neither of which was considered related to study treatment. No progressive multifocal leukoencephalopathy occurred.INTERPRETATION: Natalizumab treatment for secondary progressive multiple sclerosis did not reduce progression on the primary multicomponent disability endpoint in part 1, but it did reduce progression on its upper-limb component. Longer-term trials are needed to assess whether treatment of secondary progressive multiple sclerosis might produce benefits on additional disability components.FUNDING: Biogen.

14. A 23-GHz Low-Phase-Noise Digital Bang-Bang PLL for Fast Triangular and Sawtooth Chirp Modulation

Abstract: Frequency-modulated continuous-wave (FMCW) radars with high resolution require the generation of low-phase-noise, low-spurs, and highly linear chirp signals with large peak-to-peak value (chirp bandwidth) and a short period of the modulation signal [1]. In radar systems, the spot phase noise of the chirp generator is converted to the intermediate frequency of the receiver making it difficult to detect two close targets, while spurs cause the detection of false targets. For those reasons, medium-range radar applications in the 77-to-81GHz band typically specify spot phase noise lower than −90dBc/Hz at 1MHz offset and spur level below −50dBc. Unlike triangular chirps, saw-tooth chirps allow for a reduced dead time for range detection. However, any practical modulator needs a finite time (idle time) to make a large frequency jump at the end of the saw-tooth, and this limits the duty cycle of the saw-tooth. For instance, a fast saw-tooth chirp with 200kHz rate and 95% duty cycle leaves the idle time of only 250ns. Fractional-N PLLs can be used as chirp modulators. Unfortunately, low phase noise and spur levels require a narrow PLL bandwidth, while short idle time demands for a wide one. The two-point injection of the modulation signal, both from the modulus control of the divider and the tuning input of the voltage-controlled oscillator (VCO), is a known method to simultaneously achieve a narrow PLL bandwidth and fast modulation. However, even in that scheme, a frequency modulation error is mainly limited by gain mismatch between the two injection paths and by the linearity of the VCO [2]. In this work, a 20-to-24GHz digital bang-bang PLL, which uses the two-point modulation scheme to generate triangular and saw-tooth chirp signals, is presented. Unlike previous works [1-4], this architecture is able to generate fast saw-tooth chirps with the slope up to 173MHz/js, the idle time below 200ns, and the rms frequency error of better than 0.06%. The gain mismatch between the two modulation paths are automatically calibrated by a digital algorithm [5], and the input of the digitally controlled oscillator (DCO) is pre-distorted via an automatic background correction scheme, which compensates for the DCO nonlinearity.

Abstract: Background Though the Expanded Disability Status Scale (EDSS) is commonly used to assess disability level in relapsing-remitting multiple sclerosis (RRMS), the criteria defining disability progression are used for patients with a wide range of baseline levels of disability in relatively short-term trials. As a result, not all EDSS changes carry the same weight in terms of future disability, and treatment benefits such as decreased risk of reaching particular disability milestones may not be reliably captured. The objectives of this analysis are to assess the probability of confirmed disability worsening to specific EDSS milestones (i.e., EDSS scores ≥3.0, ≥4.0, or ≥6.0) at 288 weeks in the Tysabri Observational Program (TOP) and to examine the impact of relapses occurring during natalizumab therapy in TOP patients who had received natalizumab for ≥24 months. Methods TOP is an ongoing, open-label, observational, prospective study of patients with RRMS in clinical practice. Enrolled patients were naive to natalizumab at treatment initiation or had received ≤3 doses at the time of enrollment. Intravenous natalizumab (300 mg) infusions were given every 4 weeks, and the EDSS was assessed at baseline and every 24 weeks during treatment. Results Of the 4161 patients enrolled in TOP with follow-up of at least 24 months, 3253 patients with available baseline EDSS scores had continued natalizumab treatment and 908 had discontinued (5.4% due to a reported lack of efficacy and 16.4% for other reasons) at the 24-month time point. Those who discontinued due to lack of efficacy had higher baseline EDSS scores (median 4.5 vs. 3.5), higher on-treatment relapse rates (0.82 vs. 0.23), and higher cumulative probabilities of EDSS worsening (16% vs. 9%) at 24 months than those completing therapy. Among 24-month completers, after approximately 5.5 years of natalizumab treatment, the cumulative probabilities of confirmed EDSS worsening by 1.0 and 2.0 points were 18.5% and 7.9%, respectively (24-week confirmation), and 13.5% and 5.3%, respectively (48-week confirmation). The risks of 24- and 48-week confirmed EDSS worsening were significantly higher in patients with on-treatment relapses than in those without relapses. An analysis of time to specific EDSS milestones showed that the probabilities of 48-week confirmed transition from EDSS scores of 0.0–2.0 to ≥3.0, 2.0–3.0 to ≥4.0, and 4.0–5.0 to ≥6.0 at week 288 in TOP were 11.1%, 11.8%, and 9.5%, respectively, with lower probabilities observed among patients without on-treatment relapses (8.1%, 8.4%, and 5.7%, respectively). Conclusions In TOP patients with a median (range) baseline EDSS score of 3.5 (0.0–9.5) who completed 24 months of natalizumab treatment, the rate of 48-week confirmed disability worsening events was below 15%; after approximately 5.5 years of natalizumab treatment, 86.5% and 94.7% of patients did not have EDSS score increases of ≥1.0 or ≥2.0 points, respectively. The presence of relapses was associated with higher rates of overall disability worsening. These results were confirmed by assessing transition to EDSS milestones. Lower rates of overall 48-week confirmed EDSS worsening and of transitioning from EDSS score 4.0–5.0 to ≥6.0 in the absence of relapses suggest that relapses remain a significant driver of disability worsening and that on-treatment relapses in natalizumab-treated patients are of prognostic importance.

Abstract: The direct frequency modulation of a phase locked loop suffers from limited modulation bandwidth. To overcome this limitation, the modulation signal can be pre-emphasized by means of a high-pass filter. Unfortunately, the incorrect equalization of the PLL transfer function causes modulation error. This paper introduces a new method to adaptively match the transfer functions of the PLL and the pre-emphasis filter over environmental and process variations. The technique is verified using a time-domain model of a digital PLL designed for the generation of chirp signals for FMCW radar sensors. The new adaptive digital pre-emphasis technique enables the generation of highly-linear fast chirps with significant reduction of the idle time.

18. A low-phase-noise digital bang-bang PLL with fast lock over a wide lock range

Abstract: Digital phase-locked loops (DPLLs) based on binary phase detectors (BPDs) avoid power-hungry high-resolution time/digital converters (TDCs) while demonstrating advantages in area, power consumption, and design complexity. The introduction of digital/time converters (DTCs) enables fractional-N resolution at high spectral purity [1]. The design of a bang-bang digital PLL for wireless standards has two main challenges: quantization noise must be kept below the tolerable spot phase noise and fast lock must be guaranteed even for wide frequency steps. However, the overload of the BPD causes bang-bang PLLs to fail lock or to exhibit extremely long transients. A similar issue appears in the design of sub-sampling PLLs. This problem is exacerbated when the bang-bang PLL is designed for low phase noise for the tight resolution required of the digitally controlled oscillator (DCO). Fast locking techniques are usually based on the use of lookup tables [2], finite state machine [3], or gear shifting techniques, mostly in the field of clock-and-data recovery circuits (CDR) where spot noise performance is less of a concern. High-performance bang-bang PLLs (or subsampling PLLs) also include a frequency-aid circuit running in background [4], but its settling performance is seldom discussed.

Abstract: This paper presents the Vector Field Map PSO (VFM-PSO) as a collective search algorithm for aerial micro-robots in environments with unknown external dynamics (such as wind). The proposed method is based on a multi-swarm approach and allows to cope with unknown disturbances arising by the vector fields in which the positions and the movements of the particles are highly affected. VFM-PSO requires gathering the information regarding the vector fields and one of our goals is to investigate the amount of the required information for a successful search mechanism. The experiments show that VFM-PSO can reduce the drift and improves the performance of the PSO algorithm despite incomplete information (awareness) about the structure of considered vector fields.

Abstract: Background The monoclonal antibody natalizumab (NTZ) is a highly effective treatment for patients with multiple sclerosis (MS). However, this drug is associated with increased risk of developing Progressive Multifocal Leukoencephalopathy (PML), an opportunistic infection of central nervous system (CNS) caused by the John Cunningham polyomavirus (JCV). Objective To describe the 12-month clinical course of 39 patients with MS (28 women, 11 men) who developed NTZ-related PML after a mean exposure of 39 infusions. Methods An Italian independent collaborative repository initiative collected and analyzed socio-demographic, clinical, magnetic resonance imaging (MRI) data and number of JCV-DNA copies detected on cerebrospinal fluid (CSF) samples of patients diagnosed as affected by NTZ-related PML. The evolution of disability, measured by the Expanded Disability Status Scale, was assessed at NTZ start, at PML diagnosis and after 2, 6 and 12 months from PML diagnosis. The effect of clinical and paraclinical characteristics at PML diagnosis on the final outcome was also investigated. Results Ten patients (25.6%) were diagnosed before 24 NTZ infusions. In six cases (15.4%) the PML suspect was made on the basis of highly suggestive MRI findings in absence of any detectable change of clinical conditions (asymptomatic PML). In patients with symptomatic PML, the diagnosis was quicker for those who presented with cognitive symptoms (n = 12) rather than for those with other neurological pictures (n = 21) (p = 0.003). Three patients (7.7%) died during the 12-month observation period, resulting in a survival rate of 92.3%. Asymptomatic PML, more localized brain involvement and gadolinium-enhancement detected at MRI, as well as lower viral load were associated with a better disability outcome (p-values

Abstract: The adoption of digital-to-time converters (DTCs) along with coarse, or even single-bit, time-to-digital converters (TDCs) is known to substantially reduce jitter and power consumption of digital fractional-N PLLs. Beside these advantages, DTC-based PLLs enable an adaptive pre-distortion algorithm which mitigates the nonlinearity of the DTC and the nonlinearity-induced fractional spurs. This paper provides a novel analytical framework of this linearization algorithm and demonstrates a reduction of fractional-N in-band spurs by 25 dB in a 3.6-GHz digital PLL.

Abstract: A direct method for the evaluation by computed tomography (CT) of the neoplastic mass (tumor burden [TB]) has been adopted in 34 patients diagnosed with Hodgkin's disease in the early stage. Stressed are its prognostic value, and its correlation with the clinical and laboratory parameters usually adopted in the staging of the disease and in its follow-up. It is concluded that the CT-calculated TB is a reliable index showing good correlation with other commonly used prognostic parameters.
