Sub-THz deployment is challenging due to high propagation losses, necessitating dense deployment. To reduce cost, RF signal can be distributed via plastic fiber to remote radio units to increase coverage area. In this paper, we propose an antenna-in-package concept for the single-layer substrate on low-cost embedded wafer level ball grid array (eWLB) packages. To suppress the distortion in the bro
Background: Home mechanical ventilation (HMV), noninvasive ventilation and invasive ventilation outside a hospital setting, is a key treatment to improve outcomes in chronic hypoventilation. Research Question: What are the temporal trends observed over 27 years in Sweden regarding the incidence, prevalence, diagnostic spectrum, and patient characteristics associated with HMV? Study Design and Meth
We show that a generalization of the DAG-like query-to-communication lifting theorem, when proven using sunflowers over non-binary alphabets, yields lower bounds on the monotone circuit complexity and proof complexity of natural functions and formulas that are better than previously known results obtained using the approximation method. These include an nΩ(k) lower bound for the clique function up
A proof system P is said to be automatable in time f(N) if there exists an algorithm that given as input an unsatisfiable formula F outputs a refutation of F in the proof system P in time f(N), where N is the size of the smallest P-refutation of F plus the size of F. Atserias and Bonet (ECCC 2002), observed that tree-like k-DNF resolution is automatable in time Nc·k log N for a universal constant
When designing a hardware architecture, a designer needs to be confident that their design will meet performance requirements before moving on to the next stage in the design process. The mapping between application and architecture can have a large impact on the system performance. In this work we target early-stage system design of hardware architectures required to run a streaming application.
Bizarre parosteal osteochondromatous proliferation (BPOP) (Nora lesion) is a benign bone surface lesion, which most commonly occurs in the digits of young patients and has a high rate of recurrence. Histologically, it is composed of a mixture of disorganized bone, cartilage, and spindle cells in variable proportions and characterized by amorphous "blue bone" mineralization. Recurrent chromosomal a
To avoid being detected by radar, it is necessary to reduce stealthy military platforms' radar cross section (RCS). The operation of overlaying the metasurface (MS) on the targets is a good solution. A simple chessboard MS structure that can achieve low RCS over a large bandwidth is proposed. Only one unit cell is used to construct the MS. First, the unit cell working in 0.5 and 1−λ modes is desig
Reliability is becoming increasingly important for many applications envisioned for future wireless systems. A technology that could improve reliability in these systems is massive MIMO (Multiple- Input Multiple-Output). One reason for this is a phenomenon called channel hardening, which means that as the number of antennas in the system increases, the variations of channel gain decrease in both t
When the polar vortex meanders and shifts towards the equator, air masses from the tropics and subtropics can be transported towards the pole in so-called tropical-subtropical streamers. These large-scale structures are areas of low potential vorticity and high pressure, containing dry air with high ozone mixing ratios. The presence of these streamers can also be seen in changes in stratospheric o
Background: Myocardium at risk (MaR) can be evaluated by cardiovascular magnetic resonance (CMR) imaging using contrast-enhanced steady state free precession (CE-SSFP) in patients after ST-elevation myocardial infarction (STEMI). However, CE-SSFP utilizes gadolinium contrast, which is contraindicated in patients with severe renal insufficiency. Native T1-mapping is a non-contrast CMR method which
Reconfigurable scan networks (RSNs) provide efficient and flexible access to on-chip logic, such as instruments for test and diagnostics, throughout a semiconductor’s lifetime. Test instruments are powerful, as they provide high controllability and observability. The availability of a high number of test instruments, as well as the standardized and easy access, makes RSNs a valuable target for an
2023 marks the year when the UIA World Congress Copenhagen event turns the Øresund Region into the epicenter of global debate on architecture’s capacity to reimagine the transformation of societies into sustainable living. Celebrating this manifestation, which will commence on both sides of the Sound, LAS23 will utilize the New European Bauhaus’ three concepts -- sustainability, aesthetics, inclus
The hardware accelerated ray-tracing pipeline presents many opportunities to implement more advanced rendering algorithms than earlier rasterization based approaches. However, one particular aspect of the pipeline still remains a bit too costly to use in practice: The AnyHit-shader. Opacity Micromaps were introduced to alleviate this issue, but the central problem of calling arbitrary shader code
Abstract in Danish Formål: Formålet er at beskrive tuberkulosens (tbc.) epidemiologi i Danmark de sidste 25 år, specielt udviklingen i den danske befolkning. Metode: Et registerstudie af anmeldte tilfælde af tbc. i Danmark 1972-1996: Fra 1970-1989 i DIKE's register, fra 1990-1996 i EPI-registeret, epidemiologisk afd., Statens Serum Institut. Resultater: tbc.-incidensen faldt jævnt fra 1972 indtiThe present study is based on notified cases of tuberculosis (TB) in the National tbc. register 1972-1996. A decline in Tb incidence was seen from 1972 and until the mid-1980's. Subsequently the trend has reversed due to an increasing number of TB cases in foreigners. In 1996, 60% of all cases of TB in Denmark were found in foreigners reflecting the rising number of refugees and their families arr
Background: Several attempts to increase the locoregional control in locally advanced lung cancer including concurrent chemotherapy, accelerated fractionation and dose escalation have been made during the last years. As the EGFR directed antibody cetuximab has shown activity concurrent with radiotherapy in squamous cell carcinoma of the head and neck, as well as in stage IV NSCLC combined with che
