Distributed massive multiple-input multiple-output (MIMO) communication is envisioned as one of the key paradigms of future MIMO systems. To investigate non-wide-sense stationarities (non-WSSs) in distributed massive MIMO channels, this paper first presents an indoor channel measurement campaign, where distributed arrays with a total of 128 elements were implemented. Then relying on the correlatio

In two late Mesolithic cemeteries, dated to about 5000 BCE, at Skateholm, Scania in Sweden, some graves were found that contained clothing decorations, mainly in the form of tooth beads but also other animal parts that were used as embellishments. These are perforated front teeth, mostly from red deer but also wild boar and in rare occasions from elk and aurochs. The tooth beads were in female graIn two late Mesolithic cemeteries, dated to about 5000 bce, at Skateholm, Scania in Sweden, some graves were found that contained clothing decorations, mainly in the form of tooth beads but also other animal parts that were used as embellishments.

When investigating a settlement dated to the late Mesolithic,c.5500 cal BC, at Strandvägen in south-central Sweden, an extensive assemblageof implements made of bone and antler was found. Among these finds was a richlydecorated antler piece, likely part of an antler axe. Originally it was equippedwith shallow ornamentation that was later removed and replaced by a seconddeeper motif of longitudinal

In this article, we discuss operationalizations and examples of experimental design in eye-tracking research. First, we distinguish direct operationalization for entities like saccades, which are closely aligned with their original concepts, and indirect operationalization for concepts not directly measurable, such as attention or mind-wandering. The latter relies on selecting a measurable proxy.

Type 2 diabetes (T2D) is a polygenic disease, and the development of animal models by selective breeding is crucial for understanding its etiology, pathophysiology, complications, and treatments. We recently developed a new T2D model, the Oikawa-Nagao (ON) mouse, by selectively breeding mice with inferior glucose tolerance [diabetes-prone (ON mouse DP®; ON-DP) strain] and superior glucose toleranc

Background: Endometriosis is one of the most common causes of infertility in women. Despite extensive research on the subject, early-stage diagnosis remains challenging. Histologically, normal endometriosis does not differ from the eutopic endometrium, shifting the focus of investigation to the molecular level.Objective: To assess the immunohistochemical markers ER, PGR, Ki-67, BCL-2, and MMP-9 in

BACKGROUND: Despite absence of level 1 evidence on the long-term oncological safety of non-operative management for rectal cancer (watch and wait), increased implementation has occurred globally over the past decades. In Sweden, a pan-national prospective non-randomized study was initiated in 2017 to assess its implementation.METHOD: Patients with biopsy-proven rectal cancer receiving neoadjuvant

This chapter explores the relationship between people and forests during Japan’s Tokuagwa period, focusing on Hirosaki domain in northern Honshu, known for its abundant hiba (thujopsis dolabrata) forests. Timber production thrived in the seventeenth century, but by the eighteenth century, resource depletion prompted forest management policies. The 1783 famine accelerated forest devastation, leadin

BACKGROUND: Inadequate or excessive nociceptive control during general anesthesia can result in significant adverse outcomes. Using traditional clinical variables, such as heart rate, systolic blood pressure, and respiratory rate, to assess and manage nociceptive responses is often insufficient and could lead to overtreatment with both anesthetics and opioids. This study evaluated the feasibility

Group III-V semiconductor nanowires are a material platform with potential applications in electronics,photovoltaics and optoelectronic devices. One of the central challenges in the growth of III-V semiconductornanowires is to understand the dynamic processes that occur during crystallization. However, the growth of thesematerials is commonly performed in closed systems. There the details of the g
